So i have a 91 integra LS. 166K on the clock. My oil light came on so i stopped the car right then. I checked for oil and put some in and tried it again but light was still there. I did an oil change and new filter. I also put in a new oil pressure switch. Tried it again and the the light would get dim when the motor was running and bright when the motor was off. So i checked the wire that goes to my oil pressure sensor with a voltmeter and it only read out about 4 or 5 volts when its supposed to be 12. I put a new connector on the end of the wire to get rid of the old corroded tip and im still getting the same low voltage reading. I know im getting oil pressure because i forgot to put sealer in the oil sensor threads and the sensor wasnt very tight and it gushed oil out very fast from the oil sensor. So after i put teflon tape on the sensor and tightened it down i still have the same issues. Ive basically ruled it all out except to the wiring. The light will be on rigt before you start the motor and the ignition is on, then when i start the motor the light goes dim indicating that maybe the wire is grounding out somewhere right? Im pretty lost at this point. Am i missing somthing. Can an ICU cause the oil sensor wire to have bad voltage and cause this oil light issue? Any input is greatly appreciated.
