I did TPS voltage test on Malibu 2013 2.4L engine. Max volt was 1.8v.
Does the tps voltage increase with releationship to wheel speed sensor? or My TPS should read 4-5Volt at wot in Park or Neutral Position?
I think that the TPS cant go over 1.8V if the vehicle is not moving (wheel speed sensor).
I think you're right on about the TPS. Most drive-by-wire systems won't let you 'actually' snap the throttle wide open with the transmission in Park. No fun, right? Of course, the TPS should move full range if you go WOT in Drive.
