It means the engine may be overheating.
Engine is overheating, faulty gauge, faulty temp sensor......
No the gage has no effect on firing. An engine that is overheating will misfire.
A temperature gauge is used simply to monitor the temperature of something. They are most commonly used in vehicles to monitor oil and engine temperature to prevent any damage caused by the vehicle overheating.
If it is not overheating then the temp gage or the sending unit are bad.
The gauge on the far right side of the gauge cluster is your engine temperature gauge. The normal operating temperature is at the half-way mark. If the needle raises above the 3/4 mark then the car is overheating. A light will come on also if it begins to overheat.
We replaced the temperature gauge in my 1991 Chevy blazer what is the normal operating temp?
The engine is overheating. The check engine light is not on because you have no problem with the emissions system which this light monitors.
Check actual engine temperature with a thermometer--if in acceptable range temperature sensor or gauge may be defective
For a 2001 Ford Explorer : No , there is an engine temperature gauge Also , there is a " CHECK GAGE " light ( the light will come on if the engine coolant temperature is too high , the engine oil pressure is too low , or the fuel gauge indicates it is at or near empty )
if the temperature goes up on ur gauge but it is not overheating means ur thermostat is no good
Check the temperature sensor.
