Left Front Tire Pressure Sensor
Possible Sensor Faults
Body Control Module
Possible Related Diagnostic Trouble Codes
DTC C0750, C0755, C0760, or C0765
Circuit / System Description
The tire pressure monitor system has a radio frequency transmitting pressure sensor in each wheel/tire assembly. As vehicle speed increases, centrifugal force closes the sensors internal roll switch, which puts the sensor into rolling mode. The remote control door lock receiver receives and sends the data to the body control module (BCM). The BCM translates the data contained in the tire pressure sensor radio frequency transmissions into sensor presence, sensor mode, and tire pressure. Once vehicle speed is greater than 40?km/h (25?MPH), the remote function receiver module waits for the sensors to go into rolling mode. If one or more sensors do not go into rolling mode, or do not transmit at all, the BCM will set DTC C0750, C0755, C0760, or C0765 respectively.
