Code C0765 2016 GMC Sierra Description

The Tire Pressure Monitor System (TPMS) has a Radio Frequency (RF) transmitting pressure sensor in each wheel/tire assembly. As vehicle speed increases, centrifugal force puts the sensor into Drive mode. The sensors send the tire pressure data to the Remote Control Door Lock Receiver (RCDLR) which in turn translates the received sensor data into sensor presence, sensor mode, and tire pressure before passing it onto the Body Control Module (BCM). Once vehicle speed is greater than 40 km/h (25 MPH), the BCM waits for the first sensor to go into Drive mode, then checks if all sensors have gone into Drive mode. If one or more sensors do not go into these modes or do not transmit at all, the BCM will set DTC C0750, C0755, C0760, or C0765 respectively.

Code Tech Notes

A sensor may have been damaged due to a previous wheel/tire service or flat tire event.
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.
