Checking the cable and component

Check the signal cable between throttle position sensor #C and control module terminal #43. Check the power supply cable between throttle position sensor terminal #B and control module terminal #77. Check for an open-circuit according to Open-circuit, permanent faults .

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

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

Replace the throttle position (TP) sensor if no fault is found in the above fault-tracing.
