Why there is no voltage at the oil-pressure-sender terminals??!!
I have a 92 600SEL w/ approx 126,000 miles. the car shows very little oil pressure (if at all) at any speed. On very rare occasions it may go up to 1/2 bar and on at least one occasion it went to 1 bar.
My suspicions focused on a bad oil pressure sender and when I finally got around to doing the inspection, there was no voltage at all at the terminals which go on the sender!!
Does any body know why there is no oil pressure and why there is no voltage at the oil pressure sender terminals?
Thank you all.
