75. Continue to check for continuity between PCM connector terminal C14 and body ground, while disconnecting these parts, one at a time:
-
EGR valve 5P connector
-
Input shaft (mainshaft) speed sensor 3P connector
-
IMT actuator 5P connector
Does continuity go away when one of the above components is disconnected?
YES - Replace the part that caused an open when it was disconnected.
NO - Repair short in the wire between the PCM (C14) and the EGR valve, the input shaft (mainshaft) speed sensor, or the IMT actuator.
76. Check for continuity between PCM connector terminal D2 and body ground.
Is there continuity?
YES - Go to step 77.
NO - Go to step 76.
77. Continue to check for continuity between PCM connector terminal D2 and body ground, while disconnecting the APP sensor 6P connector.
Is there continuity?
YES - Repair short in the wire between the PCM (D2) and APP sensor A.
NO - Replace the accelerator pedal module. See: Fuel Delivery and Air Induction/Accelerator Pedal/Service and Repair
78. Check for continuity between PCM connector terminal E12 and body ground.
Is there continuity?
YES - Go to step 79.
NO - Update the PCM if it does not have the latest software, See: Testing and Inspection/Programming and Relearning/PCM Update or
substitute a known-good PCM, See: Testing and Inspection/Initial Inspection and Diagnostic Overview then recheck. If the
symptom/indication goes away with a known-good PCM, replace the original PCM. See: Engine Control Module/Service and Repair
