What sensore is it?

half_twisted · Post by **half_twisted** » Sun Feb 17, 2008 2:36 am

I just noticed a moderate oil leak behinde the block while doing an oil change. its on the back left of the block right above the vvs (speed sensore). I looked it up on the repair manual with no luck. Anyone have an idea of what sensore it is.

Thats your oil pressure switch, common to fail....

put it hasnt failed or atleast thrown a code. its just seeping oil so i thought i could just replace the Oring for it.

It won't throw a code (unless it leaks so bad you have an oil light come on!). And there is no o-ring there. It is pipe thread, and the sensor is leaking from the plastic housing where it joins the metal base. Just buy a new one, and replace it.

so do i judt buy the swich or the entire sensore?

I don't know how to put it lightly, but its sensor. No "e". Don't take it the wrong way. One time I saw the word BRAKE and went all retarted and only could think of BREAK and had no idea what brake was. D'oh.

Chrysler actually refers to it as a Switch, not a sensor. And yes "Canada" is correct, there are no to fail by the plastic separating from the metal base causing oil seepage. Just replace the whole unit and call it a day

And being a 2000 there is no code for low pressure, just the oil light. IIRC the ngc PCM might have a CEL for it but not sure. Mine didn't leak, but the contact went bad and the light wouldn't come on. EVER.

They are still on separate lights on the dash. But it's a dumb light. If it goes on, the motor is already toast, so there's really no point in having it.

My opinion: unplug it, and replace it with an actual oil pressure gauge.

You need that oil pressure plugged in for the PCM to read it or else the engine won't run, don't you? Just get a "T" and wire both stock and aftermarket in like I did... the PCM still reads the dummy light and you can actually read your oil PSI on the aftermarket guage.

00-02 You don't need the switch and it doesn't set off the oil light when disconnected.

03+ however will cause a CEL light so you'd need to hook up a T or maybe figure up how much resistance the switch has then wire in a resistor to trick the PCM into thinking the switch is still there.

I wasn't exactly sure if my car would throw a code (2003), so I teed mine off to be sure.

my bad I was watching the news and typing this between breaks.

back on the subject, I could disconect it and replace it with a oil pressure guage right. I already have a mechanical guage but dont really like having the line run through the dash incase it leaks. Im looking into an electrical guage but not sure which is more accurate.

As long as you get a good quality electric gauge they are very responsive and prolly accurate enough. With either electric, or mechanical, if you don't notice it's dropped you're done either way. I would still use an idiot light, possibly get an aftermarket one that switches at a higher psi, might take some research, but if your running a good syn oil the engine will stand a better chance running with little or no pressure for a minute or two. The more miles the better chances are for survival. Oil will soak in over time/use and will be drawn out of the bearings as they begin to "heat up" buying some time. As far as the warning light switch I would try for an older style with the stud, and splice a ring terminal to the wire. I think the older ones are a bit higher psi.

Edit: here is a link to danman's How to post #24 shows a link to the electric gauge in action.

Electric gauges, you don't have to be as careful installing them, but I can't see how they would be more accurate than a mechanical gauge. I've always used mechanical and I probably always will. Mostly because I don't want to pay $200+ for a full-sweep electric gauge. The short-sweep gauges, to me, are useless because you can't get a real quick reading out of the corner of your eye. Full sweep is much easier for me to look at. $50 for a 270-degree mechanical gauge or $200 for a 270-degree electrical. Choice made.

For the hell of it, I've never seen a drop of oil in the interior of any car that I've installed a mechanical oil pressure gauge in. That includes having the nylon tubing laying right across an HVAC duct. No issues. As long as you don't kink it at all during installation, you're set.

I have a MP white faced full sweep mechanical ready to go in my ACR. You shouldn't worry about oil in your car unless you don't grommet the hole the tube goes through (cutting the line)

Im worried about the oil seeping from the back of the guage since my teg has a oil pres guage leaking. My friend installed it before giving me the car and turns out ther its not properly grometed with the hollowed tubing. guess ill have to go out and buy the right hard ware. btw I think i have an electrical oil pres guage i havent used sinc ei bought it 5 years ago. can i just take out the current unit and install this one and some how splice the wires so my dumb light can still turn on in my dash.

Post by **Diablo0** » Fri Feb 22, 2008 8:21 pm

Nope... the stock sensor is nothing more than an on-off switch where when it drops below a set pressure (i forget exactly but pretty damn low) it turns the light on. An electric sender is different as it uses a varying voltage to control the gauge.

Kevin_GP · Post by **Kevin_GP** » Fri Feb 22, 2008 9:20 pm

Its either 3 psi or 9 psi that the stock oil light comes on, something crazy like that.

kc2005ptgt · Post by **kc2005ptgt** » Fri Feb 22, 2008 11:08 pm

Psi < 7 it comes on.
