Oil Level Sensor testing
 

I am getting a low oil warning on an engine I just put back together. I have successfully tested continuity from the sensor harness end to the 14 pin connector.

At the same time oil pressure pegs on startup - no matter which the way the the 2 pin connector is wired.

Neither of these issues were present when I pulled the engine. It may be time to replace the front engine harness, but I still would like to know how to debug the oil level sender.

Thanks.

use the multi meter to see if any of these wires are shorted ,
a good chance the insulation has failed,
and the wires are touching either at the hot post or the sender or at a clamp that holds the harness

I suppose if the oil pressure pegs with the sensor wires disconnected I need a new harness. :-(

These are the oil level sender and pressure switch wires at the clamp that holds the harness:

It looks like somebody was in there before.
These are the replacement front wiring harnesses I bought. One will replace the one above.

Well thats one way to fix a shorted wire
I would say well done brother!

Thanks Stan.

The new harness is in, car no longer shows any warnings on startup.

sounds like your wired.

Kroons?

Yes, I've used a couple of yours - had an opportunity acquire a couple of Kroon's when Pete DeJong was in Holland.

Not sure why, but I found yours easier to install.

That junction behind the DS timing belt cover is poorly thought out - the bend is a recipe for future failure. Your harness was easier to route and secure.
