Need to know what the proper oil pressure when idling and driving for 1994 jeep grand cherokee 6 cylinder 4.0 lt

If it is a 4.0 strait six cylinder this is a common problem on them.Mine was located just below the oil filter and is pretty easy to fix.Plan it on your next oil change and it is even easier to change out.Oh just so you know your 4.0 liter engines do make a little bit of noise but are pretty much bulletproof if you just do regular maintence on them.Next time you start it put your ear down by the driver side hood hinge.You will find some tapping noise there it is part of the evap system.If it had no oil pressure you would know it rite away.

jeep is known to have faulty oil pressure switches,check that first,if it's good then you have a weak oil pump.

That vehicle came with three different engine options for that year, there was a 2.5 liter inline 4 cylinder engine, a 4.0 liter inline 6 cylinder engine, or a 5.2 liter V-8 engine. Here are the firing order diagrams for all three engines and one of them should help you to solve your problem.

Use Dexron® II or ATF Plus/Type 7176 automatic transmission fluid (or their superceding fluid type).

yes you should remove the access. This will cause the engine to drown in a sense and have to fight. It is always safe to put in not enough to too much. You onlt have a certain amount of oil that can be placed in the pan before it runs up into your cylinder heads and can break the seal on the gasket. Then you would have to pay to get the cylinder head gasket replaced.

1994 is the same as 1997. parts are interchangeable

the sensor is located right above the oil filter, careful they crack very easily...but are really easy to replace...
