DTC P0B90 Chevrolet

Description

The TPM Sensors are self monitoring for internal mechanical faults (i.e. pressure sensor failure) and will send a mechanical failure message to the Remote Frequency Hub (RF Hub) Module if an internal sensor fault is detected. In the event a sensor is not able to transmit this message to the RF Hub a No Signal DTC will be logged after 20 cumulative minutes of driving above 15 mph . When the Mechanical Failure fault is active or is stored with several occurrences, the sensor should be replaced. The RF Hub records the TPM sensor IDs; and the ‘mechanical failure’ DTCs associated with them when set. The TPM-RKE tool is used to locate those IDs on the vehicle, since the location of the IDs in the RF Hub may not be correct.
