I have an "Engine System Service Urgent" warning on my message window, the code read that the AC pressure sensor needs to be replaced.

Are these things easy to replace? I have a Hayne's manual and don't see anything about it in there. Can anyone tell me where the switch is located, and/or how to replace it?

Thanks,

Mark.

 

Anyone?

 

Logically it should be somewhere on the high pressure (smaller line) side on the receiver/dryer. I would go out and look at mine but it's too dang cold.
