oil pressure sensor

[98whitelightnin]

My grandpa's truck has a faulty oil pressure sensor. Soon as you turn the kew on it shoots up to 75psi. Found the oil presure sensor but dont have the right size socket to remove it. Does anybody know the right size and best place to get a new sensor. I think Geno's will have the best price at $89. His dodge is a 2001 w/cummins of course.

don't quite know the size:shrug:, but i know the fitting that is used to remove a bathroom shower valve stem will work. After i replaced mine, everytime i accelerate the needle on my gage panel moves toward the right. It never happend with the stock. Any ideas?

It should build more pressure with more throttle.

[dripley]

The pressure should rise with the rpm.That $89 price tag looked high to me, so I looked at rock auto and whoa!!!!!! $145

[98whitelightnin]

Ya, napa wanted $209 and auto zone $199 but auto zone said they priced matched but I doubt if they would come down $110.

Must be some gold in that thing somewhere.I just noticed something, was the kid in your avatar the model for this smiley? The resembalence is uncanny.

[98whitelightnin]

Might have been, Mike and MoparMom both like my avatar.

The stock sensor never produced these results. As long as it is a normal occurance across the board, i guess i will file it as normal operation.

Mine idles about 40# and runs down the highway around 60# with the engine warm.

This is using the oe pressure gauge as a reference.

[98whitelightnin]

He is thinking about just getting a mechanical gauge but we dont know where to hook it up at.

[dripley]

There is an outlet on the leftside of the engine about midway just above the oilpan. I still have sensor there for my old booster pump. the pump was designed to come on at 5 or 10 psi so not to overwhelm the VP as I remember. I think there is a plug there but dont remeberThis is apicture of the where I had it connected.

[98whitelightnin]

Is it the 2 wire plug just under the vp lines?

[dripley]

yes.

--- Update to the previous post...

Yes. I think there is a plug there stock.

For a mechanical oil pressure guage ? I think most people just use the tets port on the oil filter dont they - right next to the turbo feed line.

The socket needed for the sender is 1 1/16" six point EXTRA deep. I bought a cheap six point deepwell socket and cut the end off that the ratchet goes in. Then I used another socket about the same outside diameter and welded them together. WALLA!! Extra deep socket!

[eddielee]

looking for specific placement for after market gauge can you install on the top of the oil filter by turbo feed line or do you need to use the left side plug midway on the block?

If you use the top of the oil filter be sure to use a 0-100 psi gauge. Cold right off the oil pump you will see almost 100 psi. The middle of the block on the left side you won't see even 70 psi.

Awesome

THANK YOU!

I appreciate the quick informative response.

I used the port on top of the oil filter for my after market gauge. Works good.

I have heard that the early 2000's for the cummins is when dodge started switching sending units. The early ones were actual pressure senders, the later ones were just a pressure switch. As long as there was like 20 psi the pressure switch would throw a number up on the gauge. This might explain the change in pressure readings.

My daughter's '98 12v is the same way. Pressure gets below 20 psi and the gauge goes to zero.
