Thanks for the reply. I assume the PCM module is the controller that sends current to low oil level sensor and then takes feedback and activiates the warning light if necessary. To answer your question directly, no I haven't checked any voltage readings. She had to leave back for Ohio shorty after I changed the sensor so I didn't get much chance to trouble shoot. The interesting thing about this warning light coming on is that before I changed the sensor the warning light came on frequently, several times during even short trips. She would reset and the light didn't stay off long..Now it seems that the light comes on shortly after she starts the car, but once she clears the warning it doesn't come back on until the next time you start the car. Seems odd that the problem has gotten better but isn't all the way fixed. I just love playing the part of a "lost ball in high weeds". If I check the voltage on the connector pins and it's low and I see no broken or shorted wires, what would be your next recommendation?
