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

Joefishizzle · 03-27-2012, 03:18 AM

Do you think by chance you have a picture? I've looked everywhere and can't find a spot for the terminal to hook up. I've felt for broken metal maybe to see if it broke off but it's all smooth. And by chance is the wire yellow with a black stripe? That's a broken hanging wire I found near the dizzy harness like you mentioned. Thanks for the help

Look in the MKIII FAQ section. here's a thread on 7M sensor locations which shows the oil pressure sensor, connector and weather boot. If memory serves me correctly the wire (it's a single wire) is yellow with either a black stripe or maybe a red stripe. It runs in the harness which runs over the engine behind the timing belt connector.

Thanks cre,
I've located the wire. I know the sensor on my motor is just under the exhaust manifold to side of the filter base. However, as stated before I can't find a terminal end for a connector to go one. Judging by the picture from the replacement part on autozones website mine looks nothing like it. Mine maybe OEM however.
I was just wondering if anyone had a picture so maybe I could see and go from there. I really don't wanna spend 55 dollars on a replacement if I don't have too.

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
