Is it overheating? If it is check the coolant level, waterpump, fan, etc. If not overheating check the wiring, temp sesnor, pcm, etc.
Does the light say check gauge or check engine?
Excessive internal engine wear? Install a manual gauge the check oil pressure
try replacing the thermostat
Have it checked for codes, it will probably have to do with the fuel level sensor in the fuel tank.
The check engine light only comes on for something that affects emissions
its orange and it is located on the right side of the gauge cluster
Is it low on Gas or Deisel? if it is that will trip the check gauge light. Or if you ever run the fuel low. It needs time to reset it self.
No , the CHECK " GAGE " light comes on if the gas gauge is at or near empty , the engine coolant temperature is HIGH , or the engine oil pressure is LOW
The check gauge light will come on if : the engine coolant temperature is too hot the engine oil pressure is too low, or the fuel level is near empty The next time the check gauge light comes on, check those 3 gauges to see if anything is outside of the normal operating range.
On a 2002 Ford Ranger : The check " gage " light comes on if : The engine coolant temperature is TOO HIGH The engine oil pressure is TOO LOW or The fuel gauge is at or near empty
If your engine light comes on and your temp gauge is lower then normal. listen for cooling fans. if they are also running chances are you need a new thermostat
When my check engine light comes on, it is caused by the temperature sensor not working. As soon as the light comes on, my temperature drops to cool. If the light goes out, the temp gauge returns to normal.
