• Ignition off.

  Check the signal cable between throttle position sensor terminal C and control module terminal 43. Check the power supply cable between throttle position sensor terminal B and control module terminal 78. Check these cables for a short-circuit to supply voltage according to Short-circuit to supply voltage. Permanent faults .

  Check the ground lead between throttle position (TP) sensor terminal A and terminal 77 for an open-circuit according to Open-circuit, permanent faults .

  Check the signal from the throttle position (TP) sensor terminal C to the control module terminal 43.

  Replace the throttle position (TP) sensor according to Replacing throttle position (TP) sensor if necessary.
