okay, i see. TPS reads angle of throttle plate for feedback to ECU in conjunction with the sensor on the gas pedal that reads Fuel demand and it lets the ECU control the Bus to determine signal to TPS, then TPS sends the feedback to the ECU, like closed loop at that point right?
I'am sure there is more involved, like associted inputs to the ECU to the determine throttle plate angle along with the gas pedal angle sensor, but that is about it right? funny how a power cable could "interfere," inducing 12VDC into the gas pedal sensor, causing a demand for WOT. I understand what they are trying to say, but it's not like the power cable is hooked up to a bus bar, with the gas pedal sensor signal wire spliced onto it between it and the ECU. Weird. anyone have problems with there car going into limp home mode that have a sub in their car
