I plugged in my scanner when my SVTF key is in the on position but not running. My Absolute TPS% is sitting at 16.5% without touching the throttle.

1. Is this normal or should it read 0%
2. Could this be part of the tune to increase fuel ratio at WOT?

Is there any danger in setting it back to 0%

2oo2 SVTF with Vortech SC and After cooler.

Thanks in advance for any help.

it should not read zero. the ecu wants to see some voltage at throttle closed. if it see's 0 the the ecu will throw a code. there wants to be some buffer between closed and wot. I dont have the specs in front of me but ususally the voltage should between 1 and 6 volts at wot

Yes that about normal , Just a correction you should be seeing between 4.2 and 5 volts at WOT , The TPS-ECU can only work in a 0-5 volt

If your car is tuned I wouldnt go changing things like tps it could mess with your tune
