- Faulty TPMS sensor in the right rear wheel
- Wiring or connection issues with the sensor
- Low battery voltage in the sensor
- Interference from electronic devices or signals
- Physical damage to the sensor or wheel
Symptoms of C0765 2018 GMC Sierra
- TPMS warning light illuminated on the dashboard
- Inaccurate or fluctuating tire pressure readings on the display
- Loss of traction or stability while driving
- Increased tire wear on the right rear wheel
- Decreased fuel efficiency
How to Fix C0765 2018 GMC Sierra
- Begin by visually inspecting the right rear tire and sensor for any visible damage or issues.
- Check the sensor's battery voltage and wiring connections to ensure proper functionality.
- Use a TPMS diagnostic tool to reset the sensor and recalibrate the system.
- If the sensor is faulty, replace it with a new sensor compatible with the vehicle.
- Test drive the vehicle to verify that the TPMS warning light is no longer illuminated and that the tire pressure readings are accurate.
Cost to Fix C0765 2018 GMC Sierra
The cost of repairing a right rear low tire pressure sensor on a 2018 GMC Sierra can vary depending on the specific cause of the issue and the cost of parts and labor. On average, the cost of replacing a TPMS sensor can range from $50 to $200, with additional costs for diagnostic testing and labor. Overall, the total repair cost for this issue may range from $100 to $400.

Tech Notes for C0765 2018 GMC Sierra
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.
