Engine problems 2013 t&c
Hello All
So I am having problems and it has stumped me beyond belief. So my check engine light came on and I hooked up the code reader and it gave me the generic P0250 I think that's what the code was anyways it say the oil pressure switch / switch circuit. All the while my oil psi is pegged at 96 not maxed out but close. So I put a new switch in and cleared the code and all seemed good until I looked at my psi and it was still is at 96. I even unhooked the oil pressure switch electrical plug and plugged it into the switch I took off and blew my air compressor into it seeing if the psi would change and it did not. The car does not over heat and no knocking in the engine the van runs superb besides the check engine light and false psi reading on my gauge.... Any help is much appreciated |
That code is a code for a turbo fault.
That sounds like a short to me. |
Correction
Code that is still displayed is P0520 it is a generic vehicle code for the oil pressure switch sensor/ switch circuit
|
OK, that is a different code than what you typed before. Numbers are swapped around.
Look for a short in the wiring. A pressure switch is nothing more than a potentiometer, as the contact increases in strength, the stronger the signal. (like a volume control.) A short could give a very high reading, like you are getting. |
OK thank you

Question
How do I find a short in the oil pressure circuit ? I have never traced out a short or ground in a vehicle and I need a starting point for this particular issue. Also why would a short all of a sudden appear from thin air? Why would that happen?
|
Grab the plug and follow the wires, look for any damage that may have exposed the wires to any ground.
Wires rubbing against a solid surface can wear thru the outer plastic casing, when it wears all of the way thru, it can short out, if the bare exposed wires touch anything that can act as a ground. |
No physical harm done to the wires and they are all intact and wrapped in heat shielding tape still I'm at a lost !!!! :(
|
Have you tried resetting the computer? It is starting to sound like a computer problem to me.
If not, disconnect the battery for about 15 to 30 minutes and reconnect. |
Yes I did I even shorted the two leads together just in case a capacitor or something was holding some kind of charge? I dunno I have racked my brain but I don't want to pay someone a ton of money to trace this thing out
