Code C0765 Cadillac Description
The C0765 Cadillac code refers to an issue with the right rear low tire pressure sensor. This sensor is responsible for monitoring the tire pressure in the right rear wheel of the vehicle. When this sensor detects low tire pressure, it sends a signal to the vehicle's onboard computer system, triggering the warning light on the dashboard to alert the driver. Low tire pressure can lead to decreased fuel efficiency, poor handling, and increased risk of tire blowouts. If not addressed, it can also cause uneven tire wear and potential damage to the wheel and suspension components.
Common Causes of C0765 Cadillac
- Faulty right rear low tire pressure sensor
- Low tire pressure in the right rear tire
- Wiring or connection issues with the sensor
- Corrosion or damage to the sensor or sensor housing
- Electronic control module (ECM) communication issues

Tech Notes for C0765 Cadillac
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.
