low oil pressure at 2k rpm

[docksider]

Need your help with isolating a trouble.

Riding in a 92 Explorer V6 4.0 Automatic 4x2. When the tach reaches 2000 RPM the oil pressure gauge goes south. Anything below 2k the gauge seems normal.

All feedback is appreciated

The first thing I'd suggest is using a mechanical guage to see if the oil pressure switch is working. I'm not sure about the '92, but on the 2000 model year, the gauge is controlled by a switch. Literally, the gauge will either read zero or normal, there is no in between.

Thanks Rod. You are right; the gauge will either read zero or normal. I closer I get to 2k the closer it gets to zero. I'll have to do more checking. Thanks again!

U nailed it. Replaced the oil sender unit (switch) and pressure gauge works like a champ.

Now I can concentrate on the noise I hear (sounds like a servo motor) when I accelerate from a stop.

Thanks again

Glad to hear you got one issue fixed. Thank you for the follow-up! I wish everyone would follow-up when the figure out the fix to their issues.
