A temperature gauge on a 1992 Chevy van may not work due to several reasons, including a faulty temperature sending unit, a broken gauge, or damaged wiring and connectors. Additionally, low coolant levels or issues with the engine's cooling system can prevent the gauge from reading accurately. If the gauge itself is malfunctioning, replacing it or the sending unit is often necessary to restore proper function. Checking the vehicle's fuse related to the gauge may also be a good first step.
Either the temperature sending unit or the gauge or the wiring in between is bad. I would put my money on the sending unit if the wire harness is plugged in and has no apparent damage.
The voltage gauge on the Blazer is not the most accurate (cheap) When using the signals the voltage draw on the system is enough to make the gauge move slightly.
have you checked the fuel gauge itself to make sure it is working
Check gauge? Never heard of a check gauge light. If you are referring to the check engine light it is on because there is a problem with the emissions system. You need to have the ECU scanned by a professional.
Check to make sure that the temperature sensor is good. A bad sensor is commonly the cause of the temperature gauge not working.
Check for a fuse in fuse block marked gauges.
the three possible problems to this question are . your temperature sending unit is defective ,you could have problems in your wiring harness, or your temperature gauge is inoperative. I am a licensed mechanic and i have found your best place to start is to make sure you have input power to the sender and sensor and output to the gauge and or light in the system .If you have no output but you have input chances are your wirings fine and the sending unit or temperature sensors bad , you'll have to refer to the proper manual and check resistance.If you have output to the gauge and you have the proper voltage reference at the gauge ,chances are the gauge could be defective. The most common problem is a defective sensor though.
Try to locate the temperature sending unit on the engine and make sure its not a loose wire to the sending unit,if the wire is in place then the sending unit is shot.
The engine is getting to hot in your 2002 Honda Civic for the temperature gauge to rise above normal. The back of fan might be failing.
The sending unit may be faulty. The year, make, model and which gauge would help.
Have you checked for leaks? also the cooling fan may not be working.
if the temperature goes up on ur gauge but it is not overheating means ur thermostat is no good
