C0760 on 2007-2014 Chevrolet Malibu: Left Rear TPMS Fault Causes and Fixes

What's Unique About the 2007-2014 Chevrolet MALIBU

On this generation of Chevrolet Malibu, the module that receives the TPMS signal (the RCDLR) also handles the key fob signals for remote entry and the anti-theft system. A GM Technical Service Bulletin (PIC5650M) has documented that a TPMS fault like C0760 can, in some cases, be associated with a no-start or engine stall condition where the security light illuminates. This is an unusual and important platform-specific issue, as a simple tire sensor problem could potentially leave you stranded. Another TSB, 16-NA-396, also notes that multiple TPMS codes can appear alongside key fob and passive entry/start failures, pointing to an internal failure of the RCDLR module itself.

Diagnostic Flowchart

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

Generation note: This year range covers the end of the 6th generation (2007-2008 'Classic'), the entire 7th generation (2008-2012), and the start of the 8th generation (2013-2014). The TPMS architecture, which uses a 315 MHz frequency and the RCDLR as the receiver, is consistent across these generations. The potential link to the security system is also relevant across this range.

Symptoms You May Notice

• Service Tire Monitor System message on the Driver Information Center (DIC).
• TPMS warning light is on or flashing.
• The pressure reading for the left rear tire shows dashes (--) on the DIC.
• In rare cases, the security light may be on. [Bulletin #PIC5650M, 3]
• Potential no-start or engine stall condition. [Bulletin #PIC5650M, 3]
• Key fob may have poor range or be inoperative.

Most Likely Causes

1. Dead TPMS Sensor Battery 🔴 High Probability → Shop Tire Pressure Monitoring System (TPMS) Sensor TPMS sensor batteries have a finite lifespan, typically 7-10 years. Vehicles in this year range are at or beyond the expected life of the original sensors. A scan tool may explicitly show a 'low battery' status for the sensor.
   How to confirm: Use a TPMS diagnostic tool to attempt to activate the left rear sensor. If the tool cannot get a reading or explicitly shows a dead battery, the sensor is not transmitting. A dealer-level scan tool may show DTC C0760 with a symptom code of :03 (Low Voltage).
   Typical fix: Replace the left rear TPMS sensor. The tire must be unmounted from the wheel to access the sensor. A TPMS relearn procedure must be performed after replacement.
   Est. part cost: $40 - $150
2. Faulty TPMS Sensor 🟡 Medium Probability → Shop Tire Pressure Monitoring System (TPMS) Sensor Sensors can fail from age, internal electronic faults, or physical damage from potholes or tire service. The use of tire sealants can also clog the sensor's pressure port, causing it to fail.
   How to confirm: A TPMS tool may show erratic or no data from the sensor. A dealer-level scan tool may show DTC C0760 with a symptom code of :39 (Internal Malfunction). Visual inspection after dismounting the tire may reveal physical damage or corrosion.
   Typical fix: Replace the left rear TPMS sensor and perform the relearn procedure.
   Est. part cost: $40 - $150
3. Radio Frequency (RF) Interference ⚪ Low Probability The TPMS sensors operate on a 315 MHz frequency, which can be disrupted by low-quality aftermarket electronics like phone chargers, dash cams, or even Wi-Fi routers if the car is parked near a house. GM bulletins specifically mention asking customers about aftermarket devices when diagnosing intermittent TPMS issues.
   How to confirm: Remove all aftermarket electronic accessories, especially those plugged into the 12V outlets. Clear the codes and drive the vehicle to see if the code returns. If it does not, one of the devices was causing interference. A dealer-level scan tool may show symptom code :29 (Too Few Pulses), indicating a corrupted or incomplete signal, which can be caused by RFI.
   Typical fix: Identify and remove the source of the RF interference.
   Est. part cost: $0

Rare But Worth Checking

• Faulty Remote Control Door Lock Receiver (RCDLR): → Shop Keyless Entry Receiver The RCDLR is the module that receives signals from both the TPMS sensors and key fobs. If you have multiple TPMS codes (e.g., C0750, C0755, C0765) and/or your key fobs are working intermittently or not at all, the RCDLR is a strong suspect. TSB 16-NA-396 specifically links these symptoms to an internal RCDLR failure requiring replacement.
• Faulty Body Control Module (BCM): The BCM processes the data from the RCDLR. While rare, an internal BCM fault can cause this code. This is usually diagnosed after all other possibilities have been eliminated.
• RCDLR Antenna Connection Issue: A less common but documented issue is a poor or disconnected coax cable connection at the RCDLR module or its antenna amplifier. This can cause intermittent loss of signal from one or more TPMS sensors, particularly those farthest from the receiver.

Diagnosis Steps

1. Check Tire Pressure: Manually check the air pressure in the left rear tire to ensure it is inflated to the specification on the driver's door jamb sticker.
2. Scan for Codes: Use an OBD-II scanner capable of reading Chassis (C) and Body (B) codes. Note any symptom bytes (e.g., :03, :29, :39) which require a professional scan tool like a GM GDS2.
3. Test the Sensor: Use a TPMS activation tool (like an Autel or VXDAS EL-50448) to attempt to read 🎬 Watch: Using the EL-50448 tool for a quick sensor relearn. the left rear sensor. The tool should display the sensor's ID, pressure, temperature, and battery status.
4. Analyze Sensor Data: If the tool shows 'No Signal' or a 'Low Battery' status, the sensor has failed and needs replacement. A good sensor should show a signal strength of at least 1/4 on the tool's graph.
5. Check for Interference: If the sensor reads intermittently, remove all aftermarket plug-in electronics (phone chargers, dash cams, etc.), clear the code, and drive to see if it returns.
6. Perform Relearn Procedure: A relearn is required after sensor replacement. For 2008-2012 models, initiate by holding the lock/unlock buttons on the key fob. For 2013-2014 models, initiate through the DIC menu. 🎬 See how to program 2013-2014 sensors without using a tool. Follow the on-screen or horn-chirp prompts to activate each sensor in sequence (LF, RF, RR, LR).
7. Inspect Receiver Module: If the relearn fails for a known-good sensor or multiple TPMS codes are present, inspect the wiring and coax antenna connector at the Remote Control Door Lock Receiver (RCDLR), which is often located in the trunk behind a trim panel.
8. Professional Diagnosis: If the sensor is good, the relearn fails, and wiring is intact, the problem may be the RCDLR or BCM, which requires advanced diagnostics and likely replacement and programming by a professional.

Parts You'll Likely Need

• Tire Pressure Monitoring System (TPMS) Sensor (OEM #13598771) — This is the most common failure point. The internal, non-replaceable battery dies, requiring replacement of the entire sensor unit. This part number is widely cross-referenced and has been superseded by other numbers, but remains a primary identifier.
  Trusted brands: ACDelco (OEM), Schrader (Often the OEM supplier), Dorman (e.g., 974-009), Bosch, Autel
  OEM price range: $90-$150
  Aftermarket price range: $37-$80

Related Codes That Often Appear With This One

• C0750, C0755, C0765 — These are the codes for the other three TPMS sensors. If multiple or all four codes are present, it points towards a central issue like a faulty RCDLR or its antenna connection, rather than multiple sensors failing at once.
• B3055, B3060 — As cited in TSB PIC5650M, these are vehicle security and key-related codes. Their presence with C0760 strongly indicates the rare but possible link between the TPMS and immobilizer systems on this platform, often pointing to the RCDLR.

Technical Service Bulletins (TSBs) & Recalls

• PIC5650M: Addresses a no-start or stall concern with the security light coming on, which may be accompanied by various DTCs including C0760.
• 16-NA-396: Details intermittent loss of Key Fob/Passive Entry functions along with multiple TPMS codes, pointing to a failed RCDLR.

Platform-Specific Known Issues

• Per GM Technical Service Bulletin #PIC5650M, this code can be found in conjunction with a no-start or engine stall condition, accompanied by an illuminated security light and other security-related DTCs like B3055 or B3060.
• Per GM TSB #16-NA-396, multiple TPMS codes (C0750, C0755, C0760, C0765) appearing with key fob and passive entry/start issues strongly points to a failed Remote Control Door Lock Receiver (RCDLR) which requires replacement.

Mechanic-Grade Diagnostic Values

• TPMS Sensor Signal Strength — expected: At least 1/4 of the graph displayed on a TPMS activation tool.. Failure: A signal strength less than 1/4 of the graph, indicating a weak sensor or interference.
• Scan Tool Pressure Reading vs. Manual Gauge — expected: The pressure displayed on the scan tool should be within +/- 27.6 kPa (4 psi) of the actual pressure measured with a manual gauge.. Failure: A variance greater than 4 psi suggests a fault with the sensor's pressure transducer.

Hidden / Shadow Codes Worth Checking

• C0760 03: Left Rear Tire Pressure Sensor Low Voltage. This specifically indicates the sensor's internal battery is failing. (see via GM GDS2 (Global Diagnostic System 2) or equivalent professional scan tool that can read manufacturer-specific symptom codes.)
• C0760 29: Left Rear Tire Pressure Sensor Too Few Pulses. This means the RCDLR is receiving an incomplete or corrupted data packet from the sensor. This often points to a weak battery, significant RF interference, or a fault in the RCDLR's receiver. (see via GM GDS2 (Global Diagnostic System 2) or equivalent professional scan tool.)
• C0760 39: Left Rear Tire Pressure Sensor Internal Malfunction. This indicates the sensor itself has an internal fault beyond just a low battery, such as a failed pressure transducer or logic error. (see via GM GDS2 (Global Diagnostic System 2) or equivalent professional scan tool.)

Scan Tool Commands That Help

• GDS2 / Tech2: Module Diagnostics > RCDLR > Data Display — Use this to view live data from the RCDLR, including the last known signal status, battery level, and hit rate from each TPMS sensor. This helps confirm if the module is receiving any signal at all from the suspect sensor.
• GDS2 / Tech2: RCDLR Setup / Programming — This function is required after replacing the RCDLR module. It marries the new module to the vehicle's BCM and immobilizer system.
• GDS2 / Tech2: Vehicle Theft Deterrent Learn — Must be performed after replacing the RCDLR. This is a 10 or 30-minute procedure that re-links the keys to the immobilizer system through the newly installed RCDLR.
• GDS2 / Tech2: Erase All Fobs — When programming fobs to a new or used RCDLR, it's often necessary to first erase all existing fob data from the module before learning the current fobs.

Wiring & Ground Locations

• RCDLR Module — Commonly located in the trunk, behind the driver's side interior trim panel on GM sedans of this era.. This is the central receiver for all TPMS signals. A loose power, ground, or antenna connection at this module can cause a C0760 or multiple TPMS codes.
• RCDLR Antenna System — Consists of a coax cable running from the RCDLR to an antenna amplifier and then to an antenna element, which on some GM models is integrated into the right rear quarter glass.. A poor connection or damage to any part of this antenna system can cause weak or no signal reception from the TPMS sensors, especially the one farthest away (often the left front).

Real Owner Repair Stories

• CorvetteForum user (2005 Chevrolet Corvette (shares RCDLR architecture)) — "No Fob Detected" message, but could start the car by giving a "little tap on the dash."
  ❌ Tried (didn't work) Repinning connectors.
  ✅ What actually fixed it The user was advised that the symptoms pointed to a cold solder joint on the RCDLR's circuit board. The fix was to remove the RCDLR, open the module, and re-solder the header pins to the board.
