Bad Sender. Bad guage.

Most likely the problem is with the Pressure Sensor in the engine block.

If the check engine light is on a malfunction that is effecting the engine emission control system has been detected If the check gage light is on , either your engine coolant temperature is too high , your engine oil pressure is too low , or your gas gauge is at or near empty

It's a common malfunction with the guage. Basically it's a poorly manufactured part and this happens when it goes out. It will require you to get a new fuel guage installed.

Most likely, the temperature gauge's connection is loose. It is usually on the thermostat. An inoperative temperature gauge will cause most check engine lights to come on.

temperature gauge not working can be caused by a bad temp sensor in engine, a bad gauge in dash, or a bad fuse

On a 2000 Dodge Ram, "no bus" means the communication network between modules has quit working. Any module on the network or the wiring between them can be the cause of the malfunction.

An inoperative temperature gauge will not alter how an engine runs, but the operator will not know if the water temperature has risen above normal without a properly working guage.

It can cause rust;Gas gauge malfunctions, and even mess with your cars computer. Not good.

The fuel control relay is mounted on the right fender, a foot aft of the battery. It is one of two cube-looking relays mounted there. It is controlled by the Electronic Engine control. Replacement is about $20.

because the engine in that car does not cool down

If you mean the temp. Gauge in a CAR; it let's you know the temperature of the water in the engine Radiator. If the temp. Gauge is at, or close to, or past the RED mark on the gauge, then the water is TOO HOT which means that it is boiling and turning to steam and most likely to burst one of the rubber hoses that carry the water through the engine casing. It is very very unwise to keep the engine going if the gauge goes to the red mark on it. You will cause expensive damage to the engine if it is not kept cool by the water being circulated by the fan in the front of the engine. Just stop the engine and call a mechanic instantly.

when the AC is on it puts more stress on the engine cause the engine has to now turn the compressor. which in turn adds more heat to the engine.

Check engine light : Gauge cluster without tachometer ( under the engine oil pressure gauge ) Gauge cluster with tachometer ( just to the left of the battery voltage gauge )

There are several reasons this could be:There is no coolant in the engine to trigger the temperature gauge, this will cause complete engine failure very quicklyThe gauge, wiring or sender are badThe engine temperature control thermostat has jammed open or it has been removed.

A boost gauge in an internal combustion engine has the role of a pressure gauge. The gauge indicates the manifold's air pressure or a turbocharger or supercharger's boost pressure.

It probably knacker your engine. It will cause the pistons to fly loose and out of time. This will cause the ngine to be rebult, might gauge out your sleeves and crack your engine head. Basics! Lav

sticking float on the fuel pump, or malfunction in the float

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

The thermometer that reads your engine temperature, I presume, is damaged or broken. Without the gauge to tell your fan how hot your engine is it will keep running as a 'better be safe then sorry' feature.

Yes, you need coolant around the sensor probe to have it function properly.
