Wheel Rotation and Sensor Training Techniques

WARNING: This page is about a different car, the 2017 Lincoln Navigator and 2017 Ford Expedition. However, it is still accessible from the selected car via links, so may be relevant.

Training known good sensors from another vehicle can help determine whether the concern is with a sensor or the TPM module. This technique cannot help determine whether the concern is due to RFI as some RFI source could be preventing the TPM module from receiving the tire pressure status from the known good sensors as well as the original sensors.

If the TPM module in the suspect vehicle cannot train any of the original sensors and also cannot train known good sensors from another vehicle, then the concern is with the TPM module or RFI and not with the original sensors. The original sensors should not be replaced. If a sensor in a certain location has caused several events, yet the sensor trains and seems to operate normally, moving that particular wheel to a different location on the vehicle is a good way to isolate the concern to a certain sensor or wheel location. Rotate the wheels and road test the vehicle. This can be done in an attempt to replicate the concern and help determine if the concern followed the sensor or remained in the original sensor location.

If the vehicle has been stationary for more than 30 minutes, the sensors enter into a "sleep mode" to conserve battery power and need to be "woken up" so they transmit the latest tire pressure information to the TPM module. Refer to Tire Pressure Monitoring System (TPMS) Sensor Activation .
