If i replace the tps can i just hook it to my scanner and set it and or do i need to relearn it?
Unhook battery, press brakes to de-power everything. Leave unhooked for half hour or more.
Re-connect the battery. Turn key to on position. Do not start the car... just to on. Don't touch the gas pedal at all. Leave for ~10-20min.
Turn key straight to start and start the car. Do not touch the gas pedal. Let idle for ~10min without touching anything.
Turn off car. Restart, drive. It might take a few heat cycles and a bit of driving before the ECU 'learns' everything over again.
