Oil Pressure (reading) Question

[overlandish]

Good morning all,

My gauge was showing low oil pressure, so I changed the oil pressure sensor and the gauge read perfectly fine for two trips at roughly 25 miles total. Then upon start up the needle just climbed right to max, and it stays there until I turn the vehicle off. When I start it, same thing happens, it just stays up top. I unplugged the sensor, and the needle fell to the bottom, like you'd expect. That makes me think it is the sensor's issue. Does this sound reasonable or is there something else I should check?

For reference, I ordered the "BECK/ARNLEY 2011763" sensor off of RockAuto.

Thanks everyone!

Non OEM strikes again! lol

I fail to see how my time and money wasted is funny, but I am glad you have entertainment from it I suppose.

I am not laughing at you. I am chuckling at the fact that this has happened to so many people on here including myself. These Cruisers are built with phenomenal parts. So every time you install a less than phenomenal part the Cruiser becomes less phenomenal. We have all learned this lesson.

Understood, thank you. The good news is, the 2UZ-FE remains phenomenal so if it is a sensor issue it will be corrected when I do my next oil change.

Entirely possible a new part fails. Either buy another or test the ones you have. Pretty sure FSM lays out how to do that using multimeter. Doesn't sound like a stepper motor issue but never know. Testing the sensor would rule some things out.

Thank you! I'll look that up.

Well, OEM sensor on the way. Lesson learned!

Update: I put the new OEM sensor in yesterday. Plugged it in, and went for a drive. It was working flawlessly until around 15 minutes into the drive it started climbing and went to max. Now regardless of engine temp when the vehicle is started the oil pressure gauge climbs to max and stays there. So similar to the last sensor, it worked for a bit and then a malfunction occurred causing it to not work, and it has not worked since.

Any clue on what could be wiping sensors out? Wiring issues possibly?

Try reading through tech stream (TS). See if still get high pressure. If not, it's likely gauge or combinations meter (dash) related.
If still high in TS, you'll have to go through diagnostic tree, looking for a fault.
Or:
Jump right into a pressure test. Which means hooking up a pressure gauge, in place of oil sending unit. But the likelihood, of actually running excessively high oil pressure in engine, is slim.

Thank you for the response. I have not dug into it any further. Mechanical gauge shows there aren't any though, so that is great. I wasn't aware that TS could read it. If that is the case, I wonder if I could get my ScanGauge 2 to read it?
