I have to do it with my Tech2, on a OBD2. Maybe you were looking at early 90's model, OBD1.
i have a code reader but it's a actron obd2 autoscanner but it doesn't say anything about my remote senser
That will not program or anything but give you generic codes. The Tech2 is the GM factory tool that does this. I have others that cost thousands of dollars that still can't do these functions.
ok brother thanks
U bet and happy trails.
