OK. First thing we need to do is check TPS voltage. Being that the TPS in this throttle body is actually two sensors, TPS1 works with opposite voltage to TPS2.
So, turn the ignition on and going by the attached graphic, check for the following voltages:
With gas pedal fully released:
Terminal 1 (Grey/White wire) - 0.3 to 1.9 volts
Terminal 4 (Yellow/White wire) - 3.7 to 4.7 volts
With gas pedal fully applied:
Terminal 1 - 4.1 to 4.7 volts
Terminal 4 - 0.7 to 2.9 volts
With ignition on, gas pedal released or applied:
Terminal 2 (Yellow/White wire) - 5 volts
Terminal 3 (Pink/Orange wire) - 0 volts (ground)
Please let me know the results and we'll take it from there.
