Right Front Tire Pressure Sensor Fault (TPMS)
The C0755 code means the vehicle's onboard diagnostic system has detected: Right Front Tire Pressure Sensor Fault (TPMS). This is a low severity code.
- Keep driving?
- Yes, but fix soon
- DIY difficulty
- moderate
- Estimated cost
- $50 - $250 (parts and labor; a single right-front TPMS sensor, higher if the RCDLR module is at fault)
Common Misconceptions / Fact Check
-
Commonly claimedC0755 is often listed generically as 'TPMS Sensor Position Mismatch.'
VerifiedOn GM vehicles C0755 is the Right Front tire-pressure sensor specifically (C0750/C0755/C0760/C0765 = LF/RF/LR/RR), most often a dead sensor battery -- not a position or relearn mismatch.

Common Symptoms
- TPMS warning light flashing then staying on solid
- 'Service Tire Monitor System' message on the driver information center
- Right front tire pressure reads as dashes or is not displayed
- Code can set from a low sensor battery even when tire pressure is correct
Probable Causes (Ranked by Likelihood)
- Failed right front TPMS sensor (dead sensor battery) Very High
- Faulty RCDLR (Remote Control Door Lock Receiver) module Moderate
- Damaged TPMS sensor wiring or weak RF reception at the receiver Low
Step-by-Step Diagnostic Procedure
-
Read BCM TPMS data with a scan tool; check the right front sensor battery status and last transmission
-
Replace the right front TPMS sensor if it shows low battery or no transmit, then perform the relearn
-
If multiple TPMS codes or key-fob reception issues are present, suspect the RCDLR module
-
Verify sensor IDs after replacement and confirm the code does not return above 25 mph
Frequently Asked Questions
What does code C0755 mean?
C0755 is a GM/Chevrolet code indicating a fault with the right front tire pressure (TPMS) sensor, most often a dead sensor battery. The C0750-C0765 codes are position-coded: C0750 left front, C0755 right front, C0760 left rear, C0765 right rear.
Can I drive with C0755?
Yes. The car drives normally, but the TPMS will not monitor the right front tire, so check that tire's pressure manually until the sensor is repaired.
How much does it cost to fix C0755?
Usually $50 - $250 -- most often a single right-front TPMS sensor plus its relearn. It costs more if the fault turns out to be the RCDLR receiver module rather than the sensor.
