oil pressure sensor

Hello,

It is under the intake manifold.

Release fuel system pressure

Disconnect and isolate the negative battery cable.

Remove the air inlet hose, upper intake manifold and lower intake manifold with the fuel injectors and fuel rail (2)

Disconnect the oil pressure sensor electrical connector (4).

Remove the oil pressure sensor (2) from the oil filter housing (3).

(Diagrams below)

Please let us know if you need anything else to get the problem fixed.

Cheers, Ken

Where is the sensor located?

It is under the intake manifold, screwed into the oil filter adapter. The upper intake comes off, then the lower with the injectors and fuel rail, then you will see the sender. The pressure sender is the three wire unit. The four wire is oil temperature.

Hello, I am attempting to replace my oil pressure sensor for my vehicle. The check engine light came on and Autozone did the check and that is what came up. So I went on line and saw you posted a picture of where it should be. The picture was not an actual picture, but a diagram. Do you have any other real pictures?

we normally only have what is supplied to us so If we sent one it would be a diagram. If you replace the sensor and it still lights up and has not been erased then it probably was not the sensor to begin with and is either a connection or wiring issue.

my oil gauge is pegging out at 80 and i had the oil changed last week and it is still full is this a problem with the gauge or the sending unit .. it will drop when i am parked and spike when i drive

Check the oil pressure with a mechanical gauge if normal replace the oil pressure sending unit abnormal oil pump pressure relief valve sticking

I have noticed recently that I have been having erratic readings on my oil pressure gauge. It has been reading between 50 and then over 80. I have checked my oil and its fine, and I have changed it recently also. I am guessing I need to change the oil pressure sender. I am not sure where it located on the engine. I could use some advice please.
I also have a lifter noise that I have been dealing with since I had the engine re-built, almost 100,000 miles ago. They told me at the shop that they could not adjust hydraulic lifters. I have a friend of mine that took a look at my top part of the engine to see if every thing was tight, and it was. He thought I had a bad lifter. Do you have any advice for this problem.
thanks

Check the oil pressure with a mechanical gauge-if normal replace the oil pressure sending unit if abnormal could be the oil pump pressure relief valve sticking/engine bearings/etc-

agree with the first poster - use a manual gauge to verify the sender / pressure.

as for the ticking... blame Jeep - they designed a poor engine that requires too much tlc to keep it from ticking. The Hydraulic lifters are not adjustable, but they are very easy to swap out. At $4 each, changing out all of them is cheap. All you need to do is have the right know how.

For the record, many people tell you to buy a specific Hydraulic Valve lifter remover - which can run you anywhere from $20 - $40. In reality, the engine is designed in such a way that you can actually use a telescoping magnet down the push rod hole and bring the lifter out without using a special tool.

I should caution however, changing out the lifters means things won't mesh the same as the originals as far as wear patterns etc go on the camshaft. Should you change just the lifters, you may actually be setting yourself up for more issues too - depending on the severity of the wear on the ones you pulled out. If possible - use a micrometer to verify how close the originals are versus the new ones before you swap. Tedious yes, but could save you a headache too.

Need to know what are the torque specs on the lower intake. And pattern. I replaced my oil pressure sensor and now I need to put it all back. Thank you.

Good evening,

I attached the torque spec for you as requested. 1. Install the oil pressure sensor (2) and tighten to 20 Nm (177 in. lbs.). Check out the diagrams (Below). Please let us know if you need anything else to get the problem fixed.
