I have a 2003 PT that is showing a oil pressure switch problem (code 522) Twice in two weeks it has stayed on at start-up on a warm engine.When shut off and restarted light went off.It has never come on while driving, and only twice ever .Question:How hard to change out and what torq going back in.I have the switch from the dealer, an it looks like it all ready has a white sealer on it.

Okay... I would suggest you get all your facts straight before telling someone how to replace PT Cruiser Oil Pressure Switch..

What need to be done is:
Raise the passenger front of the vehicle
Remove Wheel, Caliper, Tie Rod connecting to the Spindle.
Unbolt Axle
Unbolt Strut Assembly at Spindle and Remove Lower Strut Bolts.
Unbolt and Remove Axle from the Spindle
Remove Axle from the Transmission and lay aside
Now you can reach the Oil Pressure Switch to replace it.
the first answer is fine, do not waste your time doing asll that...lift it up, pull the switch and pop the new one in,.. thats it..dude above me is crazy
