My TPS sensor on my TB reads 100% all the time. I have swapped in a new sensor and nothing. I have a mustang TB and had no problems for like 2000 miles and now it won't change and its throwing off my AFR. It reads like high 11's when I'm cruising. Anyone every had this problem?

thanks in advance.

Check the wiring, if the AEM does not have an input signal it sometimes defaults to 5 volts on that channel which would read at 100%.

 

thanks.
