Review the 'Possible Causes' above and visually examine the corresponding wiring harness and connectors. Check for damaged components and inspect connector pins for signs of being broken, bent, pushed out, or corroded.
Code Tech Notes
Some aftermarket wheel valve stem holes are located further from the wheel rim than the original equipment wheels. When using the tire pressure monitor special tool to activate a sensor, ensure the tool is placed along the tire sidewall and no further than 15 cm (6 in) from the sensor and the antenna is aiming upward.
Occasionally sensors can become mislocated due to previous tire rotations where the sensor learn procedure was not performed. Always learn the sensors to ensure the DTC set is for that actual physical corner of the vehicle.
A sensor with low battery condition will set a sensor DTC but will not illuminate the low tire pressure indicator or display a message on the driver information center if equipped. The sensor battery condition can be verified in the scan tool BCM data list. If a sensor's low battery condition is indicated on the scan tool, the sensor will need to be replaced.

5. How do I fix the C0755 code on my GMC Sierra?
The fix may involve replacing the faulty tire pressure sensor, resetting the TPMS system, or repairing any damaged wiring or connections.
6. How can I reset the TPMS system after fixing the C0755 code?
To reset the TPMS, follow the owner's manual for the relearn procedure, which usually involves using a TPMS tool and adjusting tire pressures in a specific sequence.
7. How much does it cost to replace a tire pressure sensor on a 2014 GMC Sierra?
The replacement cost typically ranges from $50 to $150 per sensor, depending on whether you do it yourself or have a professional perform the repair.
8. What tool is needed to diagnose a C0755 code?
A TPMS scan tool or an advanced OBDII scanner capable of reading tire pressure sensor data is required to diagnose the issue properly.
9. How long do tire pressure sensors typically last?
Tire pressure sensors generally last 5-10 years, depending on usage and battery life. A sensor battery failure is a common reason for this code.
10. Can weather affect the tire pressure sensor and cause the C0755 code?
Yes, extreme temperatures can impact tire pressure and sensor readings, but a persistent C0755 code usually indicates a sensor issue rather than a temporary weather-related fluctuation.
