SOURCE: 2004 Grand Cherokee: oil pressure fluctuates

if you know for certain that the sending unit is correct and the guage is accurate, then yiu may have big problems.....while the engine is running open the oil filler hole.. is everything wet with oil? or does it look dry or just a little lubed? you can allways install an aftermarket oil pressure guage(crappy tire) if you get the same results with that then you may have a week oil pump....worst case scenerio... need an engine rebuild as the moter may have wear issues.does the pressure slowly drop as the motor warms up? at idle ? does it jump up when you step on the gas?

problem one is the timer control for the heaters ,also check the heaters that they are working ,oil problem ? look under the rubber boot that goes over the oil switch ,pull it back and if oil under the cover renew the oil switch,these motors do suffer from heater light flashing on and i know people have spent megabucks trying to cure it ,its a fault with dash and printed circuits ,but the heaters are not coming on i know because i have driven one with the heater circuit light coming on and i had a extended light on a long wire and the heaters are not coming on ,ignore it just renew the faulty glow plugs,as for EGR valve just pull teh vacumn pipe off the ERG valve and leave disconnect ,more hassle than its worth changing it ,you could end up with a ECU computer .Still a nice reliable motor though and economical

2007 Cadillac srx oil pressure alarm, light going off, why?


If oil level is correct, you could install a mechanical oil pressure gauge to insure you actually have good oil presure. If all is well, change oil pressure sender unit.

Oil sensor light and alarm keep going off unless accelerating. New oil and filter. Any idea's ?


Low oil pressure. Replace the oil pressure sensor, if still happens, you may need to replace your oil pump. A blown gasket will also cause a drop in pressure

I have a Saab 93 2002 Turbo 2lt with a low oil pressure warning alarm coming on. The oil level is correct and I have also replaced oil and filter. The warning light now comes on after 60km, but vanishes if...


the first thing to do is to have the oil pressure read using a mechanical gauge
that ensures that you know that the engine is running with the right oil pressure
you can test the ECM operation by using a substitute ECM that is a known good unit
run the fault codes to see in the oil pressure sensor is a problem
At this point , test the oil pressure as suggested then change the oil pressure sensor

Low oil light and alarm on at stop or slow speed


you need a mechanical .guage to connect to your engine to tell for sure if it is a real problem. but most cases a new sending unit for the oil will fix the issue. I don't know on your exact model but a sending unit is normally cheap to replace.easy to change. and normally close to oil filter. if it doesn't fix it have a mechanic check your actual oil pressure.

What does a low oil pressure alarm mean


It means the sensor that detects your oil pressure has seen a situation where the oil pressure is too low and engine damage will result. Could be just a bad sensor, but better have it checked with a mechanical gauge to see exactly what the pressure is.

Low oil pressure


Sounds like you have an internal engine problem. the only way to be sure is to check the oil pressure with an external gauge.

Oil light


The oil light typically only shows a lack of oil pressure, not a low oil level. Granted, if the oil level is so low that the pump is losing the ability to pick it up, it could activate then since the low pressure situation would be caused by an extreme lack of oil. Also, when was the last time the oil was changed? A clogged oil filter or severely dirty oil could cause an oil pressure drop.

It could be an oil pump failing, or it could also be a bad sending unit (the part that sends oil pressure data to the instrument cluster). Changing a sending unit or disconnecting it and hooking a pressure gauge to the port is usually easier than pulling the oil pan to replace the pump. If it were me, I would start there and make sure it wasn't a false alarm.

Hope this helps, and good luck!
