Default oil light has been coming on

ive got a 2003 non turbo 5 speed. it has 137k miles. this past 3 days after the engine warms up(im in north Carolina) the oil pressure light flickers and buzzes at idle. or 800-900 rpm. ive changed the oil as it did it 2 times before plus the oil was dirty. if I take the rpms about 11oo light goes out. I was going to check the wire and make sure its clean. wht else should I do?
I should not that I did change the clutch 4 k miles ago. we got the pt in aug and in sept the clutch went and it sat for 2 months before I could get to it. it runs fine
ive got 5w30 in there
I was gonna order a new sender but I want to get some advice first

use a pressure gauge as a method to test oil pressure specification at idle speed (750rpm)

it can be installed in place of the oil switch, you need to determine the thread size of the oil sending switch so it can thread into the hole.

if measurement is within calibration, your oil pressure switch is out.

but an oil switch is far cheaper than the fitting and testing instrument required to measure specification oil pressure. you may just want to order one and install it to test as well.

you would have to look up the alldata for specifications on your non-turbo engine.

this is something you want to be absolutely sure of, as problems with oil pressure can indicate an engine about to fail

We (the shop and myself) often change oil pressure senders and keep them on hand for this common occurrence with a few Chrysler model vehicles. There are also many TSB about this.

i read 4 pounds at idle for the non turbo 2.4.no load.
is that correct
I hope the engine is not going out. I so do not need it to break down.
if the switch is good, how would I find out if the oil pump is the problem or engine
if the oil pump is failing, where should I get a new one ie what brand.

There are new oil pumps available aftermarket. I doubt that your pump is failing knowing how they are engineered as well it would be rare.

Your testing should be with a manual gauge and both idle and 3000 RPM.

4psi at idle is normal

Cool Re: oil light has been coming on

a new oil pressure sensor can be had from RockAuto for a bit over 6 bucks...

2003 CHRYSLER PT CRUISER 2.4L L4 Oil Pressure Sender / Switch | RockAuto

cheap enough to sway out and see if that quiets the dash light.
