The sensor has failed, OC means out of calibration, in the case of sensor not working, or the plug got damaged. Sensor is typically in front of the radiator someplace in or near the bumper.
If the engine is not overheating and the temp gauge reads normal, the thermostat is doing its job. If the engine is overheating, the thermostat may be stuck and in need of replacement.
Low Coolant or faulty gauge
outside temp. that is what it means it is not a trick .
the 1028 is trouble code for thermostat low temp check temp gauge for low temp replace thermostat
Voltage regulator is defective. Have it replaced or this will ruin your battery.
It probably means the bulb burned out and needs to be replaced.
first let me ask you to clarify. do you mean it reads low temp or that it reads lower then what the banks and the temp outside is???? I have the same problem on my 1998 Regal. The temperature gauge reads ~ 20 degrees lower than actual. Occasionally it will read correct, but not for long. I can't find any information as to where the sensor is, or the supporting cabling that will help me trobleshoot the problem. JJD Not compared to Banks, but actual temperature readings outside. For example, if it is 95 degrees outside, the regal says ~72 degrees. It used to read withing about 1 degree to the actual outside temp, but now it is at least 20 degrees lower. I have a 99 Buick Park Avenue Ultra, and my temperature gage was doing the same thing the dealer replaced the sensor, located on the left front of the radiator. They charged me $80.00, if I had known where and what to look for I could have done it for a lot less.
It means at least one of the gauges is out of its normal range. The "check gauge light" is notifing you to take notice with either the engine temp gauge, the battery gauge or the engine oil pressure gauge.
It means that one gauge is not in the safe zone. Check the engine temp, oil pressure, battery/alternator voltage,It means that one gauge is not in the safe zone. Check the engine temp, oil pressure, battery/alternator voltage,
Your temp. sensor might be faulty, or the wiring for the gauge, but 9 out of 10 times this indicates air in the cooling system. Check the overflow tank. When there is HOT coolant on the sensor, it pops up. When air hits the sensor, it dives down.
Not sure what you really mean but if temp of heat does not change = likely bad thermostat etc. If gauge does not work at all but heat is fine then gauge or electrical type problem to the gauge
what does the root word temp mean
