Thread: Throttle position sensor testing

Are both vehicles to the same spec? If your mate has a remapped ECU and you don't then the throttle response will be vastly different. Unfortunately, it's not as simple as swapping ECUs, as the injectors are keyed in for each engine, (they have balance values that basically ensure that the ECU compensates for any manufacturing differences in flow rates etc to ensure that you get a smooth engine). A swap may work to determine why there is a difference, but the engine may be rough at idle etc.

To test the TPS, you need a diagnostic tool like the nanocom or hawkeye.

Mine is a Trs ecu manual with all the extras, my mates is a stock standard auto. I've set all mine up correctly with inj codes etc, although I realised his is far more responsive when you tap the go pedal at idle.
I do have a nanocom, but a little unsure what needs to be done to test the TPS. Maybe the guaze is blocked on the fuel pressure reg??? Or something else needs attention????

Not sure of your year models but I am sure the earlier td5's had a sharper response. Changed in the later models to reduce the bunnyhop effect when in low range low speed stuff.

Mine is a 1999 vs his 2001
