where is the oil pressure senser on 3.0 V6 ?   How difficult is it to get a manual gauge to check pressure ?

  1. Oil pressure switch is located on the front of the engine behind the serpentine belt.

    You can purchase a new sending unit for less than $15.00 So if you are going to go through the trouble of taking the old one out, I recommend installing a new one. This will save you time and money.

    Use a 27mm deep socket wrench to remove the oil pressure switch
