Oil Pressure(not what you think!READ!!)

cre · 03-27-2012, 06:45 AM

The end that the harness connector attaches to is like a nail head. A "T" from the side. The connector slides on it sideways. No idea what the autozone one looks like, but if you're looking at their website you're most likely not looking at an actual picture of the part.

Also of note is that the JDM sensor is smaller. The USDM "can" is about 2" in diameter and the JDM is about 1". They're not cross compatible.

Thank you cre again, your awesome.

I just tried to wrap a wire around the head of the sender and connected the other end to the wire and got no reading so im guess the sender is no good. Atleast that confirmed it for me. Guess I'll have to see what I can pocket at the junkyard, and if that's no good then I'll have to go into vatozone and buy one. -_-

Thanks. I'll keep you guys posted

okay so i went to the junkyard and snagged another oil pressure sender, hooked it up and didnt get anything from my gauge. so my question is before i go to buy a brand new one is there a way to test the sending unit? like with a voltmeter?

i would double check with test gauge but i dont have one. im just trying to eliminate things starting with the sending unit, seeings how all my other gauges in my cluster work

Anybody? I check the wire at my gauge and I have voltage, however when I touch my test lead to the sender unit I get nothing. Does the motor have to be on to show voltage for this? And also now that I know its good at the gauge, guess that leaves just replacing the sending unit or replacing it with an aftermarket. With the price of the replacement sender might as well

fml.....haha

For the gauge to register anything, yes, of course the engine would need to be on... otherwise it'll sit at zero just as if it were unplugged.

You could try wiring in a 10 Ohm or 25 Ohm rheostat in series with the ground/signal wire for the gauge and see how it responds as you turn the knob.

Okay so im reviving this thread cause my frustration is thru the roof. Replaced the oil sender unit with brand new part. Check to see if power is at gauge and it is. Still no oil pressure......wtf :[
