2007 to 2012 Dodge and Chrysler vehicles may have the TPMS light due to no signal from one sensor.
When codes are read from the TPMS module, you may see a code as a weak signal from a TPMS sensor or no signal from one of the wheels. When a technician checks the signal at each TPMS sensor, they are able to get a reading.
If one sensor is not communicating with the TPMS module but communicates with your test tool because the small metal (red circle) in the sensor has been damaged, most likely during a tire change.
While it is possible to inspect and, when possible, repair the old TPMS sensor, the recommended fix is to change the sensor that is sending a weak or intermittent signal.
The faulty sensor can be replaced with OEM or aftermarket TPMS sensors.
