ok so when i start my car i let it run for a while to see if the needle is going to move to let me know the engine is getting hot. the needle doesnt move but my fans come on. is my coolant sensor going bad? im not getting a cel for it. but i took the plug off and i tuned the car on and still didnt get a cel for it and the plug is not on the coolant sensor. what could be the problem?

The gauge sender is the single pin sensor on the head under the dizzy.
It won't throw a CEL if it's faulty because it doesn't feed info to the ecu.
Replace it first, then if the gauge still isn't working check the wiring and cluster

If at first you don't succeed, Try again. Don't give up too easily, persistance pays off in the end. -
Not to thread jack, but I am having a similer problem, but it is only intermitent. That is, it only happens once in a while. The guage will read totally cold, then randomly it will jump up to half-temp, stay for a moment, then back to full cold, while the car is running and at operating temp. I'll take a look at the sensor today after work.Comment
