I was woundering if anyone knows what these codes mean that I pulled off my broken car . They are 12, 21, 94, and 44. And if the meaning of the code is not self explanitory, can you explain what it means and what could cost this to happen.

Also can anone tell me where my Idle Speed Controle (ISC Valve) is and my coolant temp sensor is.

 

What codes are you pulling for an EEC codes are only 3-digits and are higher than 111.

The ISC is on the side of your throttle body, looks like a cylinder with a black rubber cap on it angled. Your coolant temp sensor, assuming you have a fox body, is on the driver side of the lower intake manifold. Cylinder 2... Its a little 5 dollar plug to replace.

 

Alright Well I droped my car off at a friends garage and he pulled the codes, my brother picked up the car so I didn't get to ask the guy any specifics but I just found this out. He say code 12 = Can't Controle RPM During Hi - RPM check. 21 = Coolant temperature sensor out of range. 94 = CCC/SS4 Circuit fault / Thermactor air inop. 44 = Thermomaetor air system not working. I have a 1989 GT. I am reading that stuff off a note and the guy doesn't have the best hand writeing so some things (like the CCC/SS4) might be a letter or something off..

 

What car do you have? http://www.shotimes.com/SHO3eeccodes3.html go by that...

 

That site doesnt say what 94 or 44 is. But does anyone know what could be causeing any of the codes that I have given? 12, 21, 94, 44

 

This website will tell you exactly what those 2 digit numbers mean. Scroll down the page a bit unti you find them. Good Luck.
