C0750 GMC Acadia (2007-2014): Left Front TPMS Fault Causes and Fixes

What's Unique About the 2007-2014 Gmc ACADIA

On the GMC Acadia and its GM Lambda platform siblings (Buick Enclave, Chevrolet Traverse, and Saturn Outlook), the Tire Pressure Monitoring System (TPMS) is integrated with the keyless entry system. Both functions are managed by the Remote Control Door Lock Receiver (RCDLR). This design means that a failing RCDLR module can cause both TPMS codes (like C0750, C0755, C0760, C0765) and key fob issues to appear simultaneously. Furthermore, a Technical Service Bulletin (TSB PIC5650) for GM vehicles explicitly links TPMS codes, including C0750, to severe electrical symptoms like intermittent no-start or stalling conditions, pointing towards a potential BCM, RCDLR, or related wiring issue rather than just a simple sensor failure.

Diagnostic Flowchart

Tap your situation to follow the diagnostic path that matches what you're seeing on this vehicle.

Symptoms You May Notice

• "Service Tire Monitor System" message on the Driver Information Center (DIC).
• TPMS warning light flashing for about a minute after startup, then staying on solid.
• The pressure reading for the left front tire shows as dashes (--) on the DIC.
• In rare cases, related to broader electrical issues, may be present alongside a "no crank" or "no start" condition with the security light illuminated.
• Key fob may have poor range or stop working entirely if the RCDLR is the root cause.

Most Likely Causes

1. Dead or Dying TPMS Sensor Battery 🔴 High Probability → Shop Tire Pressure Monitoring System (TPMS) Sensor TPMS sensors use sealed, non-replaceable lithium batteries with a finite lifespan of approximately 5-10 years. For the 2007-2014 model years, all vehicles are now at an age where battery failure is the most likely cause. A low battery condition is a primary trigger for this code.
   How to confirm: Use a TPMS diagnostic tool to attempt to 'wake up' or read the sensor. If the tool gets no response from the left front sensor while other sensors respond, the battery is almost certainly dead. The tool may also explicitly show a 'low battery' status for the sensor.
   Typical fix: Replace the left front TPMS sensor. The tire must be dismounted to access it. 🎬 Watch: How to replace TPMS sensors without a tire machine. A relearn procedure is required after installation.
   Est. part cost: $30-$70
2. Failed TPMS Relearn Procedure 🟡 Medium Probability This is extremely common after a tire rotation if the shop does not perform the TPMS relearn. The BCM expects the sensor ID from the left front position, but after rotation, that sensor is now in a different corner of the car, causing a mismatch and triggering the code.
   How to confirm: If the light appeared immediately after a tire rotation or new tire installation, this is the most likely cause. Perform the TPMS relearn procedure as outlined in the owner's manual or using a TPMS tool. A Reddit user noted that if one sensor fails to program during the relearn process, none of the sensors will report their pressure.
   Typical fix: Perform the TPMS relearn procedure. This can be initiated via the DIC or key fob and completed by using a TPMS activation tool (like the EL-50448) 🎬 See how to use the EL-50448 relearn tool on GM vehicles. to trigger each sensor in sequence.
   Est. part cost: $0 - $20 (for a basic relearn tool)
3. Damaged TPMS Sensor ⚪ Low Probability → Shop Tire Pressure Monitoring System (TPMS) Sensor Sensors can be physically damaged during tire mounting/dismounting, especially by inexperienced technicians, or by a significant pothole or curb impact.
   How to confirm: A visual inspection after dismounting the tire may reveal a cracked housing or broken stem. Like a dead battery, a damaged sensor will not respond to a TPMS diagnostic tool.
   Typical fix: Replace the damaged TPMS sensor and perform the relearn procedure.
   Est. part cost: $30-$70

Rare But Worth Checking

• Faulty Remote Control Door Lock Receiver (RCDLR): → Shop Keyless Entry Receiver While rare for a single code, this becomes a primary suspect if you have multiple TPMS codes (C0750, C0755, C0760, C0765) and/or your key fobs are also working intermittently or not at all. TSB 16-NA-396 and 16-NA-061 document this issue, stating the fix is to replace the RCDLR module. A user on an Acadia forum experienced this exact scenario, where replacing the RCDLR fixed both the TPMS and key fob issues.
• Radio Frequency (RF) Interference: Uncommon, but aftermarket devices like phone chargers, dash cams, USB power banks, or even some LED replacement bulbs can interfere with the 315 MHz signal from the sensor. TSB PIC5650 specifically advises technicians to check for these devices when diagnosing intermittent RF-related issues like TPMS faults. Try unplugging all aftermarket electronics to see if the code clears.
• Wiring or Coax Cable Issue to RCDLR: TSB 16-NA-061 points out that a disconnected or damaged coaxial antenna cable leading to the RCDLR can cause TPMS and key fob issues. Depending on where the disconnect is, it could affect one or all sensors. The bulletin advises checking the connections at the RCDLR itself, the antenna amplifier module, and the antenna in the right rear glass before replacing any parts.

Diagnosis Steps

1. Verify the tire pressure in all four tires with a quality gauge to rule out an actual pressure issue.
2. Use a TPMS diagnostic tool to attempt to read the signal from the left front sensor. This is the fastest way to confirm a dead or faulty sensor. Check the sensor's reported battery life if the tool supports it.
3. If the sensor does not respond, the sensor itself is bad (likely the battery) and needs replacement.
4. If the sensor *does* respond to the tool, the issue is likely a loss of programming or a problem with the vehicle's receiver. Attempt a TPMS relearn procedure.
5. The relearn procedure for this vehicle can be initiated by putting the ignition to 'ON' (engine off) and holding the lock and unlock buttons on the key fob until the horn chirps, putting the vehicle in learn mode.
6. Once in learn mode, the left front turn signal will illuminate. Use a TPMS tool (like an EL-50448) to activate the left front sensor until the horn chirps.
7. Proceed to the right front, right rear, and left rear sensors in that order, waiting for a horn chirp at each wheel as indicated by the turn signals. The horn will chirp twice at the end to confirm success.
8. If multiple TPMS codes are present and/or key fobs are not working, investigate the RCDLR module. 🎬 Watch this guide to locate the RCDLR module and wiring. Check for power, ground, and the integrity of its coaxial antenna cable per TSB 16-NA-061.
9. Check for sources of Radio Frequency Interference (RFI) by unplugging all aftermarket electronic devices as suggested by TSB PIC5650.

Related Codes That Often Appear With This One

• C0755, C0760, C0765 — These are the codes for the other three tire pressure sensors (RF, RR, LR). If they appear together, it strongly suggests a problem with the common receiver (RCDLR), its antenna, or a failed relearn attempt, rather than all four sensors failing at once.
• B3055, B3060 — As noted in TSB PIC5650, these security system codes related to the key can appear with TPMS codes if there is an underlying electrical or module communication problem, often caused by RF interference or a faulty RCDLR.

Technical Service Bulletins (TSBs) & Recalls

• PIC5650M: Mentions that DTC C0750 may be found with an intermittent no crank, no start, or start stall concern, along with security system codes, often due to RF interference.
• 16-NA-396: Links multiple TPMS codes (C0750, C0755, etc.) with key fob inoperability, pointing to a faulty RCDLR as the cause.
• 16-NA-061: Details how a poor or disconnected RCDLR antenna coax cable can cause TPMS codes and key fob range issues.

Platform-Specific Known Issues

• TSB PIC5650M notes that C0750 can be found in conjunction with intermittent no-crank/no-start conditions and security system codes, indicating a potential widespread electrical issue rather than an isolated TPMS fault.
• A Reddit user on r/gmc shared their experience where a single failed sensor prevented the entire system from relearning, causing all tire pressures to show as dashes until the faulty sensor was replaced and the procedure was completed successfully.

Mechanic-Grade Diagnostic Values

• TPMS Sensor Operating Frequency — expected: 315 MHz. Failure: N/A. Using an incorrect frequency sensor (e.g., 433 MHz) will result in a no-communication fault.

Hidden / Shadow Codes Worth Checking

• C0750 03: Indicates 'Left Front Tire Pressure Sensor Low Voltage'. This typically points directly to a dying or dead battery inside the sensor itself. (see via A professional scan tool like the GM Tech2 or GDS2 that can read manufacturer-specific symptom bytes.)
• C0750 29: Indicates 'Left Front Tire Pressure Sensor: Too Few Pulses'. This means the RCDLR is not receiving the expected number of data transmissions from the sensor. This can be caused by a weak sensor, RF interference, or a problem with the receiving module/antenna. TSB 16-NA-396 specifically mentions this symptom byte in relation to RCDLR failure. (see via )

Scan Tool Commands That Help

• GM GDS2/Tech2: TPMS Data Display — Use this to view live data from the TPMS module. Look for parameters like 'Tire Pressure Sensor Rolling Count' and 'Hit Rate'. A low hit rate for one sensor can indicate RF interference or a weak signal, while a rolling count that doesn't increase points to a dead sensor.
• GM GDS2/Tech2: TPMS Learn Mode — This function initiates the sensor relearn procedure from the scan tool. It is an alternative to the key fob method and is required after replacing the RCDLR or BCM.
• GM GDS2/Tech2: Module Diagnostics > BCM > Control Functions — While there are no direct bidirectional controls for the TPMS sensors themselves, you can use the BCM control functions to test other related systems and confirm the BCM is communicating properly on the data bus, helping to rule it out as the cause.

Wiring & Ground Locations

• Remote Control Door Lock Receiver (RCDLR) — Located in the rear of the vehicle, typically behind the passenger side (right) rear quarter panel trim.. The RCDLR is the module that receives the signal from all four TPMS sensors. A fault with this module, its power, its ground, or its antenna can cause one or all TPMS codes to set.
• RCDLR Antenna — The antenna is integrated into the right rear quarter glass. It connects to an antenna amplifier module, which is then connected to the RCDLR via a coaxial cable.. A disconnected or damaged coaxial cable at the RCDLR, amplifier, or glass antenna is a known cause of TPMS codes and key fob issues, as documented in TSB 16-NA-061. A disconnect can cause loss of signal from one or more sensors.
• G303 — A chassis ground point located near the base of the left 'B' pillar.. Body modules rely on clean ground connections. A corroded or loose G303 could potentially cause communication issues for modules located on the left side of the vehicle.
• G401 — A chassis ground point located near the base of the left 'D' pillar, in the rear cargo area.. This ground is in the vicinity of the RCDLR module. A poor connection here could cause intermittent RCDLR operation, leading to TPMS and key fob problems.
• G113 — A primary engine-to-transmission ground point, located at an engine-to-transmission stud on the left side of the engine.. While not directly related to the RCDLR, a poor main powertrain ground can introduce electrical noise throughout the vehicle, potentially interfering with sensitive RF modules.

Real Owner Repair Stories

• GM Forum User Discussion (2010 GMC Sierra (Similar TPMS/RCDLR architecture)) — The front passenger side tire pressure would not register, causing the entire TPMS system to show a fault. The owner had already replaced the sensor multiple times.
  ❌ Tried (didn't work) Replacing the TPMS sensor in the affected wheel multiple times.
  ✅ What actually fixed it The consensus from other forum members was that since the other three tires and the key fobs were working correctly, the RCDLR module itself was highly unlikely to be the cause. The problem had to be specific to that corner of the vehicle: either a faulty new sensor, an issue with the relearn procedure sequence, or localized RF interference affecting only that wheel's signal. The final advice was to rotate the tires and attempt the relearn again to see if the problem followed the wheel or stayed in the same corner.

"I Checked Everything" — The Actual Cause

• A common scenario is that a technician uses a TPMS tool, confirms the sensor is transmitting a signal, yet the C0750 code will not clear or returns immediately. According to GM TSB 16-NA-061, the cause can be a disconnected coaxial antenna cable leading to the RCDLR. If the cable is disconnected at the antenna amplifier module, it may only affect the sensors farthest away (like the left front), while the closest sensor (right rear) still works, making it a confusing diagnosis.
• In another case where the sensor appears to be working, the root cause can be Radio Frequency (RF) interference. TSB PIC5650 specifically calls out checking for aftermarket accessories like phone chargers, dash cams, or power inverters plugged into the vehicle's power outlets. These devices can emit RF noise that jams the 315 MHz signal from the sensor, preventing the RCDLR from receiving it, even though the sensor itself is fine.

OEM Part Supersession History

• 13586335 → 13598771, which was then superseded by 13540600. — Standard part evolution for improved reliability or manufacturing changes.
  Heads up: All parts are 315 MHz and should be compatible with the 2007-2014 Acadia. However, it is always best practice to replace sensors in a full set to ensure consistent battery life and performance.
• 13582364 → 13503205 — Likely an internal revision to address reliability issues that caused simultaneous TPMS and key fob failures.
  Heads up: The new part number 13503205 is the correct replacement. This module requires programming with GM's Service Programming System (SPS) after installation.

Model Year Variations Within This Range

• 2007-2014: There are no significant variations for this code within this specific model year range. The entire first generation up to 2016 consistently used a 315 MHz frequency for the TPMS sensors. The major facelift in 2013 did not alter the fundamental design of the RCDLR-based TPMS system.
