Oil level sensor


Recommended Posts

Ive seen the same thing before. Last time I saw it, it was due to a chewed up wire in the engine harness under the intake. Rodents love to hang out up in that area. Nice warn spot for the night with lots of wires they can chew on. This fault is usually due to an open circuit on the level sender (wiring, sensor, faulty cluster). The sensor has two circuits in it. One is a temp sensor that is wired to the DME the other it the level sensor and goes to the Instrument Cluster. The circuit to the cluster is pins 2 and 4 on the connector of the level sender. Pin 2 wire color Green and Blue and Pin 4 is Brown and orange. look at the harness closely and see if you can find any evidence of rodent damage on the wires. If it looks okay, I would next take the cluster out and check continuity of the circuit for the level sender. Gonna be pins 19 and 24 also wire color of 19 green / blue and 24 of brown / orange of connector C1. Check for Ohm reading on this circuit. I do not have a "spec" of what it should be. However if its an open circuit with no OHMS of resistance than you have a broken wire somewhere. Anyways hope this helps. Good luck

Thanks for the info.  Car is back together so I will delve into it the next time I have access to those areas again.
