Intermittent oil warning light

[sawdust123]

Four times (3 in the last week and once many months ago) the oil light has come on (or stayed on) after starting and didn't go out. Each time I stop the car and restart it and the light stays out. This has happened both before and after a recent oil change. It seems like some sort of intermittent problem with a sensor. Has anyone seen something similar?

Note: I did have the computer reprogrammed by the dealer to get rid of the overheating problem. The dealer didn't know of an oil warning problem and told me to ignore the light as everything else seems fine.

I strongly suggest another dealer. Ignore the light? Did you ask if they were joking? Perhaps the sensor was damaged due to overheating, but not for you or I to guess - there should be an error code - demand it be put right. What if there is a problem and light comes on - how would you know?
I've not seen any posts on any forum about similar problems.

I had a problem with the oil pressure sending unit in that when I would start the car occasionally the light would stay on, turn off and restart the light would go off.I purchased a new sending unit from the dealer and s special socket from PEP Boys to install it.I did check the dash for codes and got a P0522 ( I think, don't remember) which indicated faulty sending unit.Now it's fine!

Thanks LittleBlue, I'll have to put my codereader on and see if it says the same thing.

Autozone and some others will read the codes for free...

Let us know outcome.

You don't need a code reader, just turn the key off and on quickly three times and read the code in your dash.I used Rino ramps as the only good access to remove and replace the sending unit is from under the car.The hardest part is removing the electrical connector. Slide the red button all the way to the left,pinch the rear lever in the center as you pull back to remove. With the socket made for chrysler oil pressure sending units ($7.00 at PEP BOYS) and a 3" extension with a ratchet wrench it's easy! Let the car cool before attempting this as you are in close proximity to the turbo and exhaust.

sawdust123,

You have the classic symptoms of a bad oil sending unit. As of late, it appears to be a common PT problem (according to my service manager).

I still haven't had time to check out the code and probably won't for another week. If it is only a bad sending unit, I am not too concerned. I will just take it to the dealer for a replacement. I'm still under warranty and it seems that this should be something that is covered.

I plan to get an oil pressure gauge along with a few other gauges. An idiot light doesn't give me any piece of mind even when it's off. A light won't show you low pressure or changes in pressure. My 2 cents.
Sawdust....In your case, you have a sender that is "crying wolf". Get it fixed so you don't get lulled into not checking if there is a real problem.

I just spoke with the dealer. They gave me something else to ponder. It could be the oil/filter being used by my local garage. He mentioned that whatever they have been using may cause the engine to have low pressure for a longer while after startup. It seemed to me that the light should then go off by itself. However, I may not be giving it enough time to do so before I shut the engine down. Anyhow, it is time to check what the local shop is using. I've never had a turbo before so I never worried too much about oil pressure problems.
