ICP or IPR ????

Ok so I was going in to grab a coffee when I noticed a puddle of oil under the back side of my truck, boy did I freak, any how got it home cleaned the engine up real good and now I see the oil pouring out of the one sensor on top of the motor behind the oil filter, its the one with one wire coming out, Now I did replace this sensor last year, don't mind me I cant remember which one it is, does this mean the harness is bad or the sensor again too. Thanks

Replace the sensor again. The harness won't leak unless the sensor has failed.

Oh, as an edit to this, that sensor is likely the oil pressure switch. It is neither the ICP nor is it the IPR.
The IPR is mounted on the side of the HPOP, which is below and behind the turbo.
The ICP sensor for the 04 engine is mounted on the passenger side valve cover, near the alternator bracket.

any idea what the name of the sensor is, its the one with one wire going in, its right under the oil line to the turbo

I edited the above post to answer the question. I must have been editing when you posted again.

oil pressure switch. they leak all the time. I recently replaced mine

Got it, looking through my receipts and Ive replaced the oil pressure switch last november and the ipr last year as well, so is this the sensor or the plug do you think or should I replace both

Harnesses don't leak oil, sensors do.
Replace sensor, unless the oil was "pushed through" into the harness. In that case replace both (but that usually only happens on the ICP)

Ok will replace and see what happens, it never ends.
