A faulty fuel gauge sending unit in the fuel tank could cause that.
A low coolant level could cause the temp gauge not to read correctly. A faulty temp gauge sending unit could also be the cause. The coolant leak, you would have to find the source of the leak to determine the cause.
The temp sending unit may be unplugged or faulty.
could have faulty or dirty contacts, pump motor could be bad or the pressure gauge is faulty
It could be a faulty gauge, a faulty sensor, or a wiring problem. What engine do you have in what year car?
It is important to know when car parts quit working, and why. A faulty voltage regulator, blown fuse, or the wiring to the battery can cause this problem.?æ
There are a few possibilities: A bad sending unit (inside the tank), a broken wire or other faulty connection, a faulty gauge, a bad fuse...
A faulty thermostat might cause the temp gauge on the 2000 Nissan Altima to raise to hot when the car is not overheating. A faulty thermostat can cause the gauge to move up and down and might even turn the fan on.
Could be a number of reasons. The reading could even be the result of a faulty gauge set. You need to have a system performance test done to pinpoint the cause.
Faulty sender unit maybe? Or a bad earth.
Normally it causes a lower reading then higher
You temperature gauge could be not responding because of a faulty fuse. If you check your fuses and they work then you may have an electrical problem.
Could be wrong sensor or new sensor could be faulty or the gauge it self is bad
-faulty oil pres. sending unit -faulty oil pump
Could be low on oil. Oil pump could be faulty, have to check the oil pressure with a real gauge. Or, just could be the wiring or a faulty pressure switch.
Could be low on coolant (leak somewhere) or the thermostat is faulty.
Could be low on coolant or a faulty thermostat.
Engine is overheating, faulty gauge, faulty temp sensor......
Faulty signal sender in the tank.
The cause of the faulty fuel gauge is probably the fuel gauge sending unit located inside the fuel tank. Replacing the sending unit would require dropping the fuel tank.
Could be a faulty thermostat or maybe just low on coolant.
It's not fused separately. If your fuel gauge isn't working, you either have faulty wiring to the gauge, or a faulty fuel sending unit.
Yes, a faulty coolant sensor on a 99 Camaro 3.8 can cause the heat gauge to max out as soon as the car is started. It can also cause the on board computer to cut the engine power.?æ
Possible causes of gauge not working. Faulty gauge Blown fuse. Open circuit in wiring to the gauge. Temprature transmitter in engine faulty. ( most probably the actual fault ) Lack of coolant in the engine.
It could be: Bad sending unit, bad gauge, faulty wiring, corroded connector or a bad ground wire. But that's probably the ONLY things that can cause your particular problem.
