Question about 2000 Chevrolet S-10

2 Answers

I have a 1993 Jeep Cherokee. I just changed the oil and noticed ( hasn't happened before) the oil pressure gauge occasionally jumping around erratically up past the last line. I changed the oil filter again and it is still happening. Suggestions as to the problem? What should the gauge be reading normally? Thank you!

The gauge should be at around 40 psi steady and higher at higher rpms,try using thicker oil if you have high milage ,if no change go ahead replace the oil pressure switch. hope this helps you please vote.

Changed oil in my jeep grand cherokee 1999 v6,and noticed the oil pressure gage is now setting at 80psi,and the filter is correct.


Not sure about your car, but alot of times the oil gauge sending unit is kinda close to the oil filter, and maybe during the oil change the wire connection was removed or damaged. Turn the key on and engine off ,and if the gauge reads 80psi then the sneding unit might be the problem

Very first thing you need to do is install a mechanical pressure gauge on there to verify what you see on your gauge. If the actual pressure is low, then it's time to start looking inside the engine. If not, then you need to trace out the electrical problem but will know the engine is safe.

I have a '99 Jeep Grand Cherokee and occasionally the oil gauge falls then rises even though there is plenty of oil in the crankcase. what's going on??


could be a poor connection at the pressure sending unit or a partially obstructed oil pump pickup screen. If internal, often adding marvel oil will help dissolve any carbon or sludge and help with that. Also check the connection at the sender. Can also be the sender itself going bad. Pressure will normally rise and fall with engine rpm but should remain steady if rpms do not change.

My jeep also has started doing this. I replaced the oil pressure sensor. Sensor on the 4.7 is above the oil filter, follow the wires, typicaly is a 1 1/16 socket.

Oil pressure gauge doesnt work


Check the oil level. Quick lube centers often forget to refill oil, replace oil filter or drainplug. They're in such a hurry to make a buck that mistakes happen.
