Code C0765 Buick Description
The C0765 Buick code specifically refers to the Right Rear Low Tire Pressure Sensor. In modern vehicles, tire pressure monitoring systems (TPMS) have become a standard safety feature to alert drivers when tire pressure is outside of the recommended range. The right rear low tire pressure sensor is responsible for monitoring the tire pressure in the right rear wheel and sending this information to the vehicle's computer system.
Common Causes of C0765 Buick
- Faulty right rear low tire pressure sensor
- Low tire pressure in the right rear tire
- Wiring or communication issues between the sensor and the vehicle's computer system
- Corrosion or damage to the sensor or its components
- Electronic control unit (ECU) malfunction
Symptoms of C0765 Buick
- TPMS warning light illuminated on the dashboard
- Inaccurate tire pressure readings displayed on the TPMS screen
- Fluctuating or inconsistent tire pressure readings
- Loss of communication with the right rear low tire pressure sensor
- Erratic tire pressure alerts or warnings
How to Fix C0765 Buick
- Begin by checking the tire pressure in the right rear tire and inflating it to the recommended level.
- Inspect the sensor and its wiring for any signs of damage, corrosion, or loose connections.
- Replace the right rear low tire pressure sensor if it is found to be faulty or malfunctioning.
- Reset the TPMS system and recalibrate the sensors to ensure accurate readings.
- Test drive the vehicle to confirm that the issue has been resolved and the TPMS warning light is no longer illuminated.

Tech Notes for C0765 Buick
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.
