Thread: 98 buick regal air temp intake sensor code

id make sure that the car is actually seeing an input from the sensor before i tried tracking down a break in the wiring.

If you have tape on the wiring, pull it off and inspect it. I'd bet they probably twisted the wires together and that's going to corrode and cause issues. You want to clean it up, solder the wires and tape or heat shrink the connection points.
