Re: WHERE IS MY OIL PRESSURE SENSOR 1989 tpi
I think the oil pressure sender in near the distributor, but the oil temperature sensor is near the oil filter. Two different senders.
Re: WHERE IS MY OIL PRESSURE SENSOR 1989 tpi
Yeah, the last year the OP sensor was up near the distributor was either '87 or '88. My '89 has is right above the oil filter. BTW, go to your local parts store and buy the special "GM Oil Pressure Sensor" socket. Makes it wayyyy easier to replace it. Normal deep sockets aren't quite deep enough to remove the sensor, and it's a royal PITA to do it with a wrench.
