My check engine light went on and temperature gauge stopped working. I had the radiator flushed and replaced the thermostat. The temperature gauge works now but the check engine light is still on. Help!

It sounds like the engine temperature sensor has gone out but to be sure lets run the codes.

Here is the engine coolant temperature sensor location in case you get a code for the sensor.

Check out the diagrams (below). Please let us know what you find. Cheers, Ken

Thanks Ken,
Oddly enough I woke up this morning and the light was off. Roughly 24 hours. I am not going to fix what is not broke! lol, Thank you for your prompt reply and I will check into the sensor if it comes back on.
