01 Deville DHS code


Recommended Posts

•DTC P1189 Engine Oil Pressure (EOP) Switch Circuit

This code randomly pops up on a 2001 Deville DHS. I came across it pulling RIM codes and have seen it before.

Car runs fine other than throwing crank sensor codes sometimes(no surprise).

I was thinking maybe the oil pressure sending unit may be sending faulty signal at times. Where is the sensor located on the newer northstar? I know on the 90s it is just above the oil filter on the filter bypass housing. Thanks
