Check engine light on; check gages light on - 2004 Jeep Grand Cherokee

Check for a blown fuse under the dash. It will be marked gauges or instruments.

Oil sending switch needs replaced.

Check your oil level and antifreeze level or change your oil if the problem continues

The "check gages" light comes on in response to the oil pressure (not oil level) gage dropping too low. Step one is to check to make sure the engine has oil pressure. Use a mechanical gage inserted directly into the engine when the oil pressure sensor screws in. If the pressure is good, you need to check the gage. Your dealer has a tool that attaches to the connector from the pressure switch that gose to the gage. He can then test the gage, cluster and circuit wiring. If that is ok the culprit is the oil pressure sensor itself. I normally don't recommend replacing parts without a proper diagnosis but an oil pressure switch is relatively inexpensive. You might want to try that first. It's relatively common anf if that's the culprit, you will save a bunch of $$$ no having to go to your dealer. If you still have a problem, you have at least eliminated one item and are only out a couple of bucks.

The "check gage" when ever the engine coolant is high or the engine oil pressure is low. First step of diagnosis, check the coolant level and your oil level immediately and then go from there. Hopefully, this will help you to FixYa problem!

CHECK GAGES light (1) indicates a potential engine failure(low oil pressure, low coolant, coolant overheating) has occurred.
· Check gages and shut down engine. Gages should read as follows: Oil pressure 5 to 10 psi (34 to 69 kPa) at idle; Water Temp gage below 230 degrees (110 C).
· Check engine oil level (Para 2-11) if OIL PRESS gage indicates low reading. Check coolant level (Para 2-11) if Water Temp gage indicates high reading. Notify Unit Maintenance if levels are low.

If CHECK ENGINE light (2) is on, check engine oil pressure gage (3) and water temperature gage (4). If both indicate normal, proceed with mission and then notify Unit Maintenance. If either one does not indicate normal, stop engine immediately and notify Unit Maintenance

Check engine light can be any number of reasons, dirty air filter, need oil change, or more serious engine trouble. The temp gage issue is normal, this is the computer resetting itself. My car the fuel gage and temp gage do this...don't be alarmed. Take it to Advance Auto Parts and they can run a free engine diagnostics test on it to see which error code is tripping your check engine light.


Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/matthew_d24b835e574ef6ca

I just got through checking out the same van. It is most likely the instrument cluster or the bcm. Or even both.

clean throttle body...make sure disconnect battery first

Check gauge light can come on for a number of different things, from Low fuel to low oil pressure to high engine temperatures. When the light comes on check all the gauge's and see whats causing it, one or more of the gauge's will be showing an issue, Low fuel or low oil pressure, Low battery power. Any of the mentioned things can cause it... Figure out whats causing it then you can remedy the situation...
