Sensor is going batty (no, it's not the APP Sensor, did that already), so I'm just going to replace it. The connection has been checked, and this is the only code being pulled.

Is there a formal procedure for this or is the sensor PnP?

 

As far as I know it is plug and play. It's always a good idea to pull the negative battery cable when working on electronics.

 

No procedure listed in the SM, so looks like PNP.
