Oil Pressure circuit code P0522
My 98 just threw code P05220--engine oil pressure sensor circuit voltage low. The oil pressure gauge went to zero. I don't know if it has anything to do with it, but it was raining when I was driving it. Possibly some water causing a short? Or does the oil pressure sensor need replacing?
Any ideas would be appreciated.
the engine oil pressure (eop) sensor changes resistance based on engine oil pressure. the pcm monitors the signal circuit of the eop sensor.when the oil pressure is high, the sensor resistance is high, and the pcm senses a high signal voltage. whe the oil pressure is low, the sensor resistance is low and the pcm senses a low signal voltage. the pcm sends the engine oil pressure information to the ipc via the class 2 serial data circut. read again,
with all that being said is the code now history?
inspect for poor connections at the harness connector of the eop sensor.
pretty common for the eop to go bad from what i have read,
good luck
