Hey everyone,
My wife's 2006 Cayenne S has a check engine light on with code P2229-Cooling System Performance - implausible signal from Durametric software. Through my research I only found "P2229- barometric pressure sensor high voltage" and "P2181-thermostat stuck open" so I am a bit confused as to what this code is telling me...if I reset the DTC, it will come back on if I drive on the highway for about 15-20 minutes when starting from cold. If we drive to a few stores in between cold start and operating temp, the DTC won't appear. This is leading me to a thermostat problem, but I would like some advice from anyone on here before I spend 6+ hours putting a new thermostat in.
