Hi .

This code is more than the C1201 as you have recorded .

Attached is the repair sheet for this problem .

First if you have any other codes check and repair this first as other codes have been known to trip this code .

Still need additional information then please get back to me with the reply button, and not the poor or bad service, this way i can get back to you or suggest another expert if needed.
