In the 2007-2012 Dodge and Chrysler vehicles, the TPMS light may come on due to a damaged TPMS sensor even though the sensor tests OK with a test tool. The TPMS light often comes on intermittently.

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.
