Infiniti G35 C1711 Code: Rear Left TPMS Sensor Fault Causes & Fixes (2004-2008)

What's Unique About the 2004-2008 Infiniti G35

For this G35 generation, Infiniti issued a Technical Service Bulletin (ITB13039A) specifically warning that radio frequency (RF) interference can cause a 'No Data' condition, triggering codes like C1711. 🎬 Watch: How to read TPMS codes on your G35 This means aftermarket accessories like phone chargers, dash cams, or even certain mobile phones can block the sensor's signal. This should be the first diagnostic check. Additionally, the 2004-2008 model years span two different G35 generations (V35 and V36), which use different TPMS sensor part numbers, making it crucial to verify the correct part for your specific year.

Diagnostic Flowchart

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

Generation note: The 2004-2008 range covers two G35 generations: the V35 (2004-2006 Sedan, 2004-2007 Coupe) and the V36 (2007-2008 Sedan). These generations use different TPMS sensors. The V35 models typically use part number 40700-CD001. The V36 models use part number 40700-JK00B or its successors. Always verify the part with your VIN.

Symptoms You May Notice

• TPMS warning light flashes for approximately 60-90 seconds after starting the car, then stays on solid.
• Inability to view the tire pressure reading for the rear left tire on the vehicle's information display (if equipped).
• A 'Tire Pressure Low - Add Air' message may appear on the display, even if the tire pressure is correct, followed by the flashing light on the next startup.

Most Likely Causes

1. Dead TPMS Sensor Battery 🔴 High Probability → Shop Tire Pressure Monitoring System (TPMS) Sensor The non-replaceable batteries in the original sensors have a lifespan of 5-10 years. All vehicles in the 2004-2008 range are now well beyond this service life, making battery failure the most common cause.
   How to confirm: Use a TPMS activation tool at the rear left wheel. If the tool cannot get a response from the sensor (no ID, pressure, or temperature reading), its battery is dead or the sensor has failed.
   Typical fix: Replace the rear left TPMS sensor. It is often recommended to replace all four sensors at once, as the others are likely to fail soon.
   Est. part cost: $30-$75 per sensor
2. Radio Frequency (RF) Interference 🟡 Medium Probability Infiniti TSB ITB13039A specifically identifies RF interference from aftermarket devices as a cause for C1711. Cheap or poor-quality USB chargers, wireless phone chargers, and dash cams are the most common culprits, as they can emit RF noise that blocks the 315 MHz signal from the TPMS sensor.
   How to confirm: Unplug all aftermarket devices from the vehicle's power outlets (cigarette lighter sockets). Clear the code (if you have a scanner) or drive the vehicle for 10-15 minutes to see if the light turns off on its own.
   Typical fix: Remove or replace the interfering electronic device with a higher-quality, better-shielded version.
   Est. part cost: $0 - $30
3. Faulty TPMS Sensor (Internal Failure) ⚪ Low Probability → Shop Tire Pressure Monitoring System (TPMS) Sensor Beyond the battery, the sensor's electronics can fail from age, moisture ingress from a bad valve stem seal, or physical damage during tire service.
   How to confirm: If the sensor responds to a TPMS tool but cannot be registered to the vehicle, or provides erratic data, it has likely failed internally.
   Typical fix: Replace the faulty TPMS sensor.
   Est. part cost: $30-$75 per sensor

Rare But Worth Checking

• Faulty TPMS Control Unit / BCM: This is very rare. If a new, known-good sensor cannot be registered to the rear left position, and there is no RF interference, the Body Control Module (BCM) or the dedicated TPMS receiver may be at fault. A scan showing multiple communication codes (like U1000) alongside TPMS codes could point to a broader BCM or low vehicle voltage issue.
• Corroded or Damaged Valve Stem: The TPMS service kit, which includes the valve stem, grommet, and nut, can corrode over time, causing air leaks or damaging the sensor itself. While this more often causes a leak, severe corrosion can compromise the sensor's function. It is standard practice to replace this service kit whenever a tire is dismounted.

Diagnosis Steps

1. Verify the symptom: Confirm the TPMS light flashes for ~60 seconds on startup before staying solid.
2. Scan for codes: Use an OBD-II scanner capable of reading Chassis (C) codes to confirm C1711 is present and check for other related codes. Alternatively, use the manual procedure of grounding the TPMS service connector to flash diagnostic codes via the TPMS light.
3. Rule out RF Interference: Unplug ALL aftermarket electronics (phone chargers, dash cams, radar detectors, etc.). Drive the vehicle for at least 10 minutes at speeds over 25 mph to see if the light resets.
4. Activate Sensor: Use a TPMS diagnostic tool to attempt to read the signal from the rear left sensor. The tool should display the sensor's ID, pressure, temperature, and battery status.
5. Analyze Activation Results: If the tool gets no response, the sensor is dead and must be replaced. If the tool reads the sensor, but the car still shows the code, the issue may be with the vehicle's receiver or the sensor ID is not correctly registered.
6. Relearn Procedure: If a new sensor is installed, a relearn procedure is mandatory. This can be done with a TPMS tool via the OBD-II port. Some owners have had success with a manual 'no-tool' method involving grounding a specific wire and setting tires to specific pressures, but this is more complex.

Parts You'll Likely Need

• Tire Pressure Monitoring System (TPMS) Sensor (OEM #40700-JK00B (V36) / 40700-CD001 (V35)) — This is the part that fails, most often due to its internal battery dying. The 2007-2008 V36 generation uses part 40700-JK00B or its successors (40700-JK00C, 40700-JK01C). The earlier 2004-2006 V35 generation uses a different part, 40700-CD001.

Related Codes That Often Appear With This One

• C1708 — This code is for the Front-Left sensor. Seeing multiple TPMS codes together (C1708, C1709, C1710, C1711) often means all sensor batteries are dying from old age or there is a systemic issue like RF interference.
• C1709 — This code is for the Front-Right sensor. When seen with C1711, it suggests a systemic issue like multiple dead batteries or RF interference.
• C1710 — This code is for the Rear-Right sensor. It's very common to see C1710 and C1711 together as the rear sensors fail around the same time due to age.
• U1000 — This is a CAN communication circuit fault. If seen with TPMS codes, it could indicate a broader electrical issue with the BCM or wiring, rather than just a failed sensor.

Technical Service Bulletins (TSBs) & Recalls

• ITB13039A: Discusses TPMS diagnostics and explicitly mentions radio frequency interference causing 'No Data' conditions for codes C1708, C1709, C1710, and C1711.

Platform-Specific Known Issues

• As per TSB ITB13039A, these vehicles are known to be sensitive to radio frequency interference from aftermarket electronics, which can mimic a failed sensor and cause a C1711 code.
• A manual 'no-tool' relearn procedure exists, which is popular in owner forums. It involves locating a single-pin TPMS service connector near the OBD-II port, grounding it multiple times to enter learning mode, setting each tire to a unique pressure, and then driving the car.

Mechanic-Grade Diagnostic Values

• BCM Power Supply Voltage (Ignition ON) — expected: Approx. 12V. Failure: Significantly lower or no voltage indicates a power supply harness issue.
• BCM Ground Circuit Continuity — expected: Continuity (YES). Failure: No continuity (open circuit) indicates a faulty BCM ground circuit harness.
• TPMS Receiver Power Supply (V36 models) — expected: 12V DC on the violet wire. Failure: No voltage points to a wiring or fuse issue before the receiver.
• TPMS Receiver Ground (V36 models) — expected: Continuity to ground on the orange wire. Failure: No continuity indicates a bad ground connection.

Hidden / Shadow Codes Worth Checking

• 18: Rear Left tire pressure drops. This is a manufacturer-specific code, not a standard OBD-II 'C' code. (see via Ground the single-pin TPMS service connector (near the OBD-II port) and turn the ignition ON. The TPMS dash light will blink out two-digit codes. A long blink is the first digit, short blinks are the second.)
• 41-48 (e.g., 47): Transmitter battery voltage low for a specific wheel (e.g., 47 is for Right Rear). This directly indicates a dying sensor battery. (see via Ground the single-pin TPMS service connector and count the blinks from the TPMS dash light.)

Scan Tool Commands That Help

• Nissan CONSULT-II / CONSULT-III+: ID Reg / Work Support for TPMS — This function is used after installing new TPMS sensors. The tool puts the BCM into 'learning' or 'execution' mode. The technician then uses an activation tool at each wheel (LF, RF, RR, LR) to force a transmission, and the CONSULT software registers the new sensor ID for that position.

Wiring & Ground Locations

• Body Control Module (BCM) — Located under the driver's side kick panel, attached to the interior fuse block.. On most V35 models, the BCM contains the TPMS receiver. A bad ground or power connection to the BCM can cause various TPMS faults, including C1711.
• TPMS Control Unit / Receiver — On some later models (V36 generation), this is a separate module located behind or underneath the glove box.. This module is the dedicated receiver for the TPMS sensor signals. If it fails or loses power/ground, it cannot receive data from any sensor, leading to communication codes.
• M91 (TPMS Check Connector) — A single-wire connector, usually white, taped to the wiring harness near the OBD-II port under the driver's side dash.. This connector is intentionally placed for diagnostics. Grounding this wire is required to initiate the manual diagnostic code reading and the sensor relearn procedure.
• BCM Ground (E105, Pin 8) — Pin 8 (Black wire) on the main 40-pin BCM connector (E105).. A poor ground at this specific pin can cause intermittent and difficult-to-diagnose electronic issues, including TPMS malfunctions. Verifying continuity here is a key step if sensors and receivers check out.

Real Owner Repair Stories

• G35Driver Forum user 'Maine35X' (2007 Infiniti G35X) — Flashing TPMS light with multiple codes indicating no signal from any wheel, plus no signal from RH front and RH rear receivers, despite sensors transmitting a strong signal when checked with a shop tool.
  ❌ Tried (didn't work) Verifying tire pressures., Attempting the manual 'pressure-set' relearn procedure multiple times., Replacing the TPMS receiver module located behind the glovebox.
  ✅ What actually fixed it The user reported the problem started after major work on the front differential. The final fix was not posted, but the evidence strongly suggests the root cause was a damaged wire or a bad ground connection disturbed during the prior repair, not a faulty TPMS component.

"I Checked Everything" — The Actual Cause

• A known diagnostic pattern for this code is when a TPMS activation tool confirms the sensor at the wheel is transmitting a strong signal, yet the car still logs a C1711 'no data' code. This rules out a dead sensor battery. The cause in these cases is almost always upstream: either the sensor ID is not correctly registered in the BCM, there is a fault with the TPMS receiver/BCM itself, or there is a wiring/ground issue between the receiver and the BCM.

OEM Part Supersession History

• 40700-CD000 → 40700-CD001 — Revision/update
  Heads up: Applies to V35 generation (2004-2007).
• 40700-JK00A / 40700-JK00B → 40700-JK01C — Multiple revisions and consolidations.
  Heads up: The full supersession chain for the V36 sensor is JK00A > JK00B > JK00C > JK00D > JK00E > JK01A > JK01B > JK01C. Using an early part number might work, but the latest revision, 40700-JK01C, is the correct service replacement.

Model Year Variations Within This Range

• 2004-2007 (V35 Generation): Uses TPMS sensor part number 40700-CD001. The TPMS receiver function is typically integrated into the Body Control Module (BCM) located under the driver's dash.
• 2007-2008 (V36 Generation): Uses TPMS sensor part number 40700-JK00B and its successors. May use a separate, dedicated TPMS control unit located behind the glove box, in addition to the BCM.
