Hi, I’m wondering what each of the three sensors located next to the oil filter housing do. I wanted to replace them, but I didn’t know exactly which ones do what.

Hello,

The engine has 2 oil pressure sensors.
Behind the alternator, below the intake, at the rear of the engine.
See picture below.
Number 1 is the oil pressure switch and number 2 is the reduced oil pressure switch. Number 1 will be blue, and number 2 is brown.

Hope this helps.

Cheers, Boris

Thank you Boris, that was really helpful but would you happen to know what the third connection in that diagram is? Because I also have to replace it.

Hello,

The third connection is the oil pressure control solenoid, item 7 in image below.

Cheers, Boris
