A faulty temperature sending unit. It should be located on or near the thermostat housing. If any of your gauges reads zero, the check gauges light will come on. Sometimes even if the fuel gauge gets too low, it will trigger the light. It may be the connection at the sending unit. It may have become loose so wiggle it and make sure it is securely connected to the sending unit. If the temp. gauge needle pegs at the top of the gauge, it means the sending unit has grounded out and is faulty. If it jumps, reads off or not at all it could be a faulty sender or a bad connection.

Oil pressure


A mechanic would check the oil pressure with a mechanical gauge by taking out the sensor. Could be a problem with the gauge in the cluster.

Check gauges light comes on 1993 chevy 1500


If the check gauges light come on it refers to charging system, oil pressure, and engine temperature.So check the oil level,and you will need to know if the pressure is good. cooling system are you loosing coolant and is the radiator full, battery is the system getting charged. Now on the lighter side it can just be a faulty gauge

I have a 2001 Dodge Ram 1500 When Im driving for awhile the check gauges light comes on and oil gauge come down


You either have good oil pressure and a bad oil pressure sending unit, or your oil pressure really is low. Get it checked out, so you don'y destroy the engine.

Gauges work fine when engine's started, then oil gauge falls below zero and warning light comes on saying "Check gauges," so I check the oil and transmission fluid levels and these are fine but...


start by checking the ground strap to the engine, and engine to body. The oil pressure sender unit may be bad. You may have to hook up an oil pressure gauge to the oil pressure sender port to verify proper oil pressure. Senders are cheap- I would just replace it and go from there.

The oil pressure guage on my 2000 Jeep Grand Cherokee is registering 0. My oil was just changed and I don't see any indication of oil leaking anywhere. Could it be the sensor?


First off I wouldnt drive your car until you make sure that you have indeed oil pressure and that the gauge is a false reading, driving your car if in fact it has no oil pressure will severly damage your engine, but firstly i would check the oil pressure switch its located on the passenger side of the engine right back from the oil filter make sure the connector is clean and free from oil and corrosion if the connector appears to be in good shape take a paper clip and insert it between the 2 terminals inside the connector your oil pressure gauge should peak at 80 PSI that tells you that your gauge and all related wiring are good and in working condition, secondly remove the oil pressure switch and hook an manual oil pressure gauge up to you engine and start the engine the guage should have a oil pressure reading anywhere from 30 PSI to 55PSI depending on engine temperature if theres oil pressure on your manual gauge replace the oil pressure switch with a new unit, if you still have 0 PSI on your gauge then stop your engine immediatly and start looking at your oil pump and lubricating system for a problem.

Why won't the oil and temperature gauge work on


you should switch the temperature sensor and oil pressure sensor you had on your first engine,because your new engine must come with the light indicator dashboard so the sensor of your new engine are not compatible with your gauges....lipak!...

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...

OIL PRESSURE LIGHT COMES ON AND PRESSURE GOES TO 0 ON GAUGE


Any time the oil pressure is 0 you take a chance of locking up the motor. The only way to know for sure is to put a pressure gauge in the oil pressure sending unit port on the engine and see what the pressure really is. At that point you will either have the peace of mind in the knowledge that the sending unit is really bad and needs replacement or you can then contact a repair shop and tell them what your testing has revealed. I wouldn't drive or run your truck while the oil pressure is at zero.

Good luck
