I just made a simple diagnosis run on my brothers 06 I4 manual Colorado and noticed what I thought was an anomaly with the throttle position readings. Minimum TP was 12.2% and max was 89.4% at WOT. The only other throttle by wire system I've logged in is my LB7 (D-max) and it always shows 0% at idle and 100% at WOT throttle. So my question is: Is this the way it should operate or should I be seeing 0% at idle and 100% at WOT? If it's wrong could I have done something wrong with the EFI live scan tool/software?
Thanks in advance for your help!
