Setting tps 2001 Gt

Just installed a new TB on a 2001 Gt car idles good but on shifting now the rpms drop to like 300 immediately, could this be that the tps just needs adjusting?

Yea that sounds exactly like a TPS sensor that needs to be adjusted. I think Ford charges ~ 80 dollars to do it. If you want to do it yourself you'll need a digital voltmeter and patience.

Re: Setting tps 2001 Gt

Here's a little how to

Tuning the TPS

When you tune up your Mustang (wires, plugs, timing, etc.), the checking/adjustment (if needed) of the TPS should always be included. You will need a Phillips screwdriver, a pin, and a voltmeter that can read low voltages accurately. Here is the procedure:

1) Loosen the two screws holding on the TPS, (The screws can be very stubborn, so make sure you have a good quality screw driver that fits snug and has a long handle for lots of torque, or you might strip the heads) just enough to able to swivel the TPS with force.
2) Pierce the "GREEN" wire with the pin and hook the positive (+) lead from the voltmeter to it.
3) Ground the negative (-) lead from the voltmeter. Use a good ground, like the engine or other grounded metal source.
4) Turn your ignition key to the run position, but do not start the vehicle
5) Rotate the TPS until you achieve .98 to .99 Volts (For stock or slightly modified engines).
6) Tighten the screws on the TPS and recheck.


If the maximum or minimum voltage you can obtain is close to the above recommended voltage setting (.98-.99), but the TPS just won't turn enough to get it right, you will have to modify the TPS. If you get a very low voltage reading, make sure you have an accurate voltmeter and your connections are solid, if so, you need to replace your TPS. If you have no voltage, you have a bad connection or a bad voltmeter. Rarely, if never, will a TPS be in such bad shape, especially if your car still runs good
