    Hi all!

    i just got my first tundra (2012 off road trd with the 5.7 v8). I have a sensor I noticed that the wires have been ripped out of. I don’t have any warning lights going off and all my gauges appear to be functioning normally.

    what sensor is this? I obviously want to replace it but can’t figure out what it is. Thanks!

    Appears someone bypassed your A/C pressure switch. You'll need an A/C specialist to look at it. If your A/C still works? It's probably not a good idea to run it like that.

    That is the high pressure switch. It’s purpose is to shut off the compressor when the hi side pressure gets too high.

    I think @lr172 is correct..

    The red wire goes to pin 1
    The white with black stripe goes to pin 2
