Check the wires to the senders for grounding Those gauges have a power lead to gauge then to sender. The more the sending unit "grounds" the higher the gauge reading

Has 358000 miles, just had leaks repaired. Twice since my oil pressure gauge reads no pressure but not all the time? Why


1. Oil Pressure Gauge Not Working You will notice this happens when your oil pressure gauge is not reading, whether the engine is turned off, idle or running. Try to step on the gas to rev up the engine. If the oil pressure gauge still doesn't change its reading, your gauge is busted. It's best to replace it as soon as possible because you won't have any idea if your car is already overheating or not.
2. Oil Pressure Gauge Reading Too Low When your engine is idle, the oil pressure gauge will have a low reading. When the engine starts running or when you're already cruising or on the freeway, your gauge's reading should have increased. If it stays on a low reading, then you now your oil pressure gauge is broken.
3. Oil Pressure Gauge Reading Too High Another common oil pressure gauge problem is when your oil pressure gauge is reading too high when your engine is idle or when it's turned off. Rep

Oil pressure guage reading max


Remove the sending unit on the engine and check the oil press with a test gauge, if the oil pressure is good on the test gauge replace the oil press sending unit on the engine. Note the removal and installation of the sending unit requires a special socket, that is available at any auto parts store, you will likely need the deep version of that socket for a Chrysler product.

The oil pressure at idel is fine however when you put a load on the engine it will drop to 0 and when the load is off the pressure will go back off. Is it a oil pump or gauge?


to check the gauge you need to remove the wire from the sending unit and ground it for an instant with the ign. on. a good gauge will go to the top of the scale. if the gauge goes to top of scale then replace sending unit. if the gauge does not go to the top of scale replace the gauge. also check your wiring from gauge to sending unit for faulty wires. if all of this is good then your pump i partly pluged at the screen or faulty and u will need to replace it. hope this will help!!!

Oil pressure gauge not working ,need to know location of same.


Oil Pressure Sensor Testing
  1. Check the oil level and correct as necessary. Turn the ignition switch on, but do not start the engine.
  2. Disconnect the sensor lead at the sensor. The gauge should read full scale.
  3. Ground the connector. The gauge should read at the bottom of the scale.
  4. If the gauge functions properly, replace the sensor.

  1. If necessary, remove the engine sight shield.
  2. Disconnect the oil pressure sensor electrical connector.
  3. Using J 41712 or equivalent, remove the oil pressure sensor.

2002 Jeep Grand Cherokee 4.0L oil pressure gauge reading too high


if the gauge starts a 0 - goes to 1/2 , than full - sounds like gauge is OK - seems to me like the sending unit is bad - you could try removing the sender and trying to clean out the port with "brake clean", letting it dry than re-installing it. the pressure switch is still the least expensive place to start

Guage reading high


It is not hard to change the sending unit. I reccomend that you remove the sending unit and hook up a test gauge, then you will know if your pressure is actually too high, or not.

I had the same problem and ended up changing the oil pump and it did not fix it. (Peace of mind anyway and it was cheap) I replaced the pressure sensor (that happens to be tucked in deep between the back of the engine and firewall) and the pressure gauge worked just fine after that.
