Check Oil Panel Light is Flickering when on Idle.

I just bought a Dodge Intrepid Base 2000 2.7L V6 Engine that has a mileage of 127,590. My mechanic said that the car is running in good condition and no problems. The car runs smoothly and very quiet.

After a couple of days I noticed that the oil lights always flickers every time I got out from the freeway and go to stop in a traffic light (RPM:500).

I changed my synthetic oil twice and changed the oil filter. Also, flushed my transmission fluid. My mechanic also cleaned the engine oil pan for possible oil sludge and changed the oil gasket. My mechanic said that the oil pressure drops when my car is on idle. Still the problems occurs and so I went back and they changed the seal of the engine oil pan. My mechanic also changed the sensor. Now, the problem is still there and it still flickers (blinks) every time I got out from the FREEWAY and stop. When I drive in a CITY ROAD and stops, the problem does not occur. I am getting annoyed that my mechanic cannot solve my problem. Please help me.

Try a new oil pressure sensor from the dealer the aftermarkets don't work.

Do an actual oil pressure test, if OK THEN get the dealer sender unit.

oil pressure at hot idle can drop as low as 5 pounds,, go to the dealer,, get a CHRYSLER oil pressure sending unit you should be good to go, remember dealer part only, bout 19 bucks

As long as you don't have any other engine problems or noise, you don't have an issue to worry about, hot oil pressure on the higher mileage 2.7 is often unusually low, especially with synthetic and thinner oils. Do an actual pressure test and as stated above, replace the sending unit with an OEM Mopar unit if the old one is bad.

Yes, no mechanical noise.

They did change the oil sensor already.

They did an oil pressure test and it is fine.

Would they install it for me for how much or just buy the parts and let my mechanic assemble it?

What about the oil pressure switch connector and wire terminal/vent? Do you think it causes that problem too?

Thanks guys.

Obviously, if the connector to the switch is loose you will have a flickering issue, but that seldom is the cause. If you are operating in over 50 degree temps you could jump up to 10W30 or 10W40 conventional oil and see if the change helps the idle oil pressure. In over 70degree temps here in Florida I ran 20W50 in my 2.7 and had great pressure all the time.

I live in Los Angeles, California and we use 10W40. I am going to change the oil switch this week. My mechanic changed the oil sending unit already and the problem still occurs.

Nope. What is the difference? If I let Chrysler change it, how much would it cost?

Thanks guys.

There was something odd that I noticed in my car. When I drove my car on the freeway for 10 miles around 8-10am to my work, the check oil light was flickering every time I got out the freeway and stop. However, I drove my car from Los Angeles to San Diego (100 miles) and the check oil light did not flicker last night because it was cold.

I have new issues that my coolant air bleeder has small leakage. My mechanic is charging me for $135 for the parts and repair. Is that a good price? Is it possible to seal it instead of changing the parts? If I don't change it, what would happen to my car?

I am sorry guys if I ask a lot of question. I just bought the car 2 weeks ago and this is my first car. I also have few background on car mechanics and I am starting to learn.

Where is it leaking from and what part (s) does your mechanic suggest to replace?
