[QUOTE="xackley, post: 441534, member: 17509"] jack up the rear, spin the tire so the drive shaft rotates. If you get no signal, you have narrowed the problem. You could the test the sensor with a multimeter, when spinning the wheel it should generate some AC voltage. If it generates voltage you then have to check the connectors and wiring. And the temperature should be around room temperature if the vehicle has been sitting. It is red on purpose because it is out of range. Chryslers ECU reaction to a problem sucks, Example, I had a bad connection to O2 sensor 1 bank 1. Instead of going to open loop, it shut off the gas to the entire bank causing a very lean multiple miss fire. Don [/QUOTE]
