As a cautionary note, the bolts that hold the TPS to the throttle body are steel and the throttle body is aluminum. Unless the bolts had a bitumus coating applied to them before they were installed, it is possible for the bolts and throttle body to fuse together. I found this to be the case for me when I needed to replace my TPS. In the end I twisted the heads off the torx bolts to get the TPS off. With firm grip on the shaft (yeah, that's right
) with Vice GripsŪ I managed to remove one but broke the other off flush with the throttle body.
I ended up drilling out the broken bolt and putting a helicoil in.
