I ran my codes today after the check engine light came on and it gave me a P1290-cylinder head temperature (cht) sensor ckt low input. What does this mean?
Thats the only thing that came up. And it came up after I installed my cai and started it with the stock tune installed. But, I had drove the car a few miles before it ever came on. (my intake requires a tune, but the tune doesn't work right so I had to go back to stock...long story) Would the intake cause this kind of code? What is cht?
