Chrysler Repair: oil light flicker on Sebring convertible: 2.7L, oil pressure switch, oil pressure sending unit

Question
QUESTION: is the answer the same for  2001 seabring convertibles with the 2.7 as it was for the answer for Jason about his 2001 Concorde. i have changed the oil from 5w 30 to 10 w 30, replaced the  oil pressure sending unit ,  cleaned the oil pick up screen which had little debrie , car runs and and changes fine with no engine knocking. but the light is driving me crazy. what else can you suggest to get the light to stop flickering? Someone suggested that the ECM could be going bad, but i don't understand how that could effect the light flickering..

ANSWER: Hi Tim,
You are correct about the ecm not being involved in the oil pressure warning lamp function. If the light comes on/flickers at idle when the engine is warmed up, but quickly goes out with raising of the rpm I would not be concerned about that. It is rather common and not of concern. The time to be concerned is if it comes on when you have the rpm over about 1200 rpm or so. And of course very concerned if at higher rpm's to the point of pulling over and cutting off the engine.

QUESTION: one last question ...  when we sprayed tte oil sensor down with water to cool the engine and sensor down the light stopped flickering and went off. Is there anything else  to do to keep sensor cool,
if i have the following added do you think it would help and still work properly if the oil is low. part to add is as followed,,adding a (terminal/wire/vent)to the oil pressure switch or is a such thing made if so where can i find one to buy?

Answer
Hi Tim,
May I suggest a couple of things? Because you are concerned about this, why not take off the sensor switch and test the pressure with a gauge screwed into the port to see what it actually is at idle and at 3,000 rpm. It should be at least 5 psi at idle, and 45-105 at 3,000 when the engine is warmed up. Even before you do that, notice the rpm at which the light goes on, or off if different. Then while you have the pressure gauge installed see what the psi is at that same rpm. Thus you will know if the gauge is pessimistic or optomistic when the light is on, compared to the spec. For example if you determined that the light comes on at 10 psi then you would know that it is still safely above the 5 psi spec.  
I also notice that the manual for the '03 Sebring says that there is a heat shield around the sensor on the 2.7 engine. Do you find that to be the case? If not, go to a dealer parts counter and have them check their parts computer to find it and it will show how to install it. I would not go beyond what the manufacturer has designed in terms of modifying the set up.
