Oil light on while driving 2002 Sebring

Have you checked the oil level in the engine? Without suffient oil, the oil pressure will drop.

Sounds like bad oil pressure switch. Is the engine making any loud noise(s)? I'd replace oil pressure switch and/or check connection at oil pressure switch.

How is the sensor connected to the engine? I had a 2000 model Pajero which did the same thing. It had to do with the way the sensor was connected to the engine, the hollow bolt they used was aftermarket and didn't let enough oil through to the sensor. So the oil has to warm up first before it can get through to the sensor.

Anytime the oil light goes on, I would think that the pressure has dropped, assuming the oil sending unit is working properly.

How long ago was the engine oil changed?
I had a low oil pressure signal in a 1997 Cadillac Deville LImousine which went away after I had the engine oil changed.

Sometimes, the wrong viscosity or oil break down can cause the oil pump not to generate enough pressure for the oil pressure light to go on.

I looked at the Recalls for the 2.7L engine and couldn't find anything regarding engine oil pressure light going on mistakenly, but this doesn't mean that it's not a problem on your vehicle. There are 2 other sized engines for this vehicle.

So, what's the engine size for this Chrysler Sebring?
Does the engine smoke at all after all of this?

This fix works for 2.7L engine. Worth having your mechanic look at.

Answer
NO: 08-36-99
SUBJECT: Engine Oil Pressure Light Flicker
DATE: Oct. 15, 1999
OVERVIEW:
This bulletin involves adding a terminal/wire/vent to the oil pressure switch connector.

NOTE: THIS BULLETIN APPLIES TO VEHICLES EQUIPPED WITH A 2.7L ENGINE.

SYMPTOM/CONDITION:
With a hot engine the oil pressure light may be on or flicker on at idle.

DIAGNOSIS:
Verify engine oil pressure as described on page 9-21 of the 1999 Concorde/Intrepid/LHS/300M service manual (Publication No. 81-270-9140). If engine oil pressure is within specification perform the Repair Procedure.

PARTS REQUIRED:
Qty Part No. Description
1 05017800AA Wire Terminal/Vent


REPAIR PROCEDURE:
Raise vehicle on a suitable hoist.
Remove engine oil pressure switch connector from switch.
Remove sealing dart from the empty cavity at the rear of the connector.
Pull terminal locking ring outward from front (switch) side of connector to gain access to terminal locking tabs.
Install wire terminal/vent, p/n 05017800AA, in place of the removed sealing dart. Slide locking ring back into place.
Attach the connector back on the oil pressure switch.
Spot tape the wire/vent to follow the harness towards the top of the engine compartment.

replace the oil pressure sending unit

Could be a bad oil pressure switch, or a bad oil pump. Both will cause this issue. Hope it is the switch b/c the oil pump is a costly repair.

without confirming oil pressure,(not level)are within normal specs,I would replace the oil pressure switch,If you need the location let me know. DB

You need to have oil pressure checked manually with oil pressure guage. There is a good possibility that the engine has excessive wear or a bad oil pump and oil pressure is really low. (It's like have a bad heart) That would definitely trigger oil light.If you have low pressure and its not taken care of immediately it will ruin the engine from lack of lubrication to vital parts.
