Checking the cable and components

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 77. Check these cables for an open-circuit according to Open-circuit, permanent faults .

Check signal cable terminal C on the throttle position (TP) sensor for a short-circuit to ground according to Short-circuit to ground, permanent faults .

HINT: The throttle position (TP) sensor receives 5 V from engine control module terminal 78. 

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

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