The C0755 code means the vehicle's onboard diagnostic system has detected: Tire Pressure Monitor Sensor Not Transmitting (Right Front) (GM). This is a moderate severity code.
- Keep driving?
- Yes, but fix soon
- DIY difficulty
- moderate
- Estimated cost
- $50 - $150 (usually one TPMS sensor battery/unit + relearn)

Frequently Asked Questions
What does C0755 mean?
C0755 is a chassis code used primarily by GM vehicles: Tire Pressure Monitor Sensor Not Transmitting (Right Front). It concerns the tire pressure monitoring system.
Can I keep driving with C0755?
Generally yes; the tire pressure monitoring system may be degraded. Diagnose soon, and treat any brake- or steering-related behavior change as urgent.
Is C0755 the same on every make?
The decimal C0xxx range is dominated by GM's assignments (Chevrolet, GMC, Buick, Cadillac). Other makes may use this ID differently - if your vehicle is not a GM product, verify the meaning in your make's service information.

Step-by-Step Diagnostic Procedure
-
Read the code with a GM-capable scan tool and note the symptom byte/subcode if shown.
-
View live data for the named circuit (e.g. all four wheel speeds while rolling for wheel-speed codes).
-
Inspect the circuit's wiring and connectors - chassis harnesses live in the splash zone and corrode first.
-
Follow the GM pinpoint test for C0755 before replacing components.
Common Misconceptions / Fact Check
-
Commonly claimedC0755 is often listed generically as 'TPMS Sensor Position Mismatch.'
VerifiedOn GM vehicles C0755 identifies the Right Front tire-pressure sensor specifically (C0750/C0755/C0760/C0765 = LF/RF/LR/RR). The dominant cause is a depleted sensor battery, not a position or relearn mismatch.
