If installing a throttle position sensor do you have to reset your computer.....and if so what happens if you don't.......also how can you tell if you have a bad sensor.....like if you bought a new one, is there anyway you can test it?

shouldn't time frame should be around 10 mins minimum. You may need someone to adjust the computer with the proper equipment.

check your catalytic converter as well hit it with the side of you hand to listen for any loose peices inside

Suggested Repair

Disconnect the battery for at least 10 minutes to clear stored codes; positive or negative terminal should not matter. If the no-start continues, have the computer adjusted with proper equipment. Also tap the catalytic converter and listen for loose pieces inside.

Conversation Summary

The owner of a 1995 Ford Escort replaced the throttle position sensor after a scan indicated it had failed. The car ran briefly, then would not start; with the old sensor it started but had no power and bogged under hard throttle. The expert advised clearing codes by disconnecting the battery for about 10 minutes, said positive versus negative should not matter, suggested the computer may need adjustment with proper equipment, and recommended checking the catalytic converter for loose internal pieces.
