: Engine code - EOP

11-12-07, 04:45 PM
2001 DTS. I got a code off my dash P1189 for Engine Oil Pressure (EOP) Switch Circuit. I read that this could be due to the fact that the sensor is loose and not connected. Where would I find this sensor to connect it again?

The oil pressure switch is on the oil filter adapter. If you need to replace it, be sure to use an A/C Delco switch.
