Okay, so the Check Engine light has come on and gone off a couple of times now in Christy's 4.0 WJ. I checked the code and it's P0123 - Too high voltage at throttle position sensor. Before I go throwing parts at it, has anyone on here seen this before? Sensor from Jeep is about $50 or $32 from O Reilly. The Jeeps got about 65,XXX miles on it and the 80k powertrain warranty doesn't cover engine management sensors.
I've never changed a TPS before. Is it just a plug and play or is there some sort of calibration involved?
Please help me get my wife off my case :whip: ,
