Throttle Position Sensor

[underdog1924]

Can a fault throttle position sensor affect gas mileage? I've heard several different opinions and wanted to get a more solid answer. Also any suggestions on how to get the screws out of it? They are really in there and soft. If I turn too much they will be stripped. I've been hitting them with WD-40, any other suggestions? Thanks burn_out

Use a pair of Vice-Grips to spin the screws, rather than a scredriver.

These are notoriously difficult to get out without stripping. Just get them out and go somewhere like pep boys and get new bolts. You'll probably only find them with hex heads.

The TPS is more capable of causing driveability problems than affecting gas mileage. A malfuntioning TPS can cause a surging idle, hesitation during off-idle tip-in, hesitation during part-throttle tip-in or bucking on throttle let up.

I tried to replace the TPS a few days ago but completly stripped one of the screws to the point where I can't get it out.

For those of you that can't afford an impact driver with a phillups bit on it, you can always use a regular phillups screwdriver ans a small hammer. Just put the screwdriver in the screw head and press in hard and "start" the un screwing motion. As soon as the screwdriver is encountering resistance from the screw, give the back of the screwdriver handle a slight tap with a hammer. It works very well even on stripped screw heads. But in the long run you should get a real impact driver.

Thanks guys. I've tried several times with a screwdriver and pliers. I'll try the hammer thing next, but after that I have no idea what to do. Thanks for the help though.

I got mine on today thanks to vice grips. It was easy after I got the stripped screw off. A five minute process at the most.
