Hello. The code you are getting is for what is known as the PremAir sensor. This is the ozone air detection sensor. They are a common failure on this vehicle. The sensor can usually be tested with a scan tool which is what I would typically do before replacing it. If the sensor passes the tests then it may be a circuit issue. Most of the time the sensor itself just needs replacing.
