Where is the oil pressure sensor located?

Hello, you'll have to remove the engine control module, disconnect the 2 engine master harness wiring harness retainer and evaporative emission canister purge solenoid valve hose, remove the transmission mount bracket bolt  and transmission mount bracket, and then access the oil pressure sensor. I'd recommend obtaining access to a workshop manual to get the illustrations and instructions for more clarity. Have you verified proper oil pressure, or are you guessing a sensor will repair your concern?
