Checking wiring
Check the flywheel and carrier plate for damage.
Check the signal cables between engine control module (ECM) terminals #24 and #54 and engine speed (RPM) sensor terminals #1 and #2. Check for an intermittent short-circuit to supply voltage according to Short-circuit to supply voltage, intermittent faults . Check for an intermittent short-circuit to ground according to Short-circuit to ground, intermittent faults . Check for an intermittent short-circuit to each other or for an intermittent open-circuit according to Open-circuit, intermittent faults . Remedy if necessary.
HINT: With the ignition on, the voltage between engine speed (RPM) sensor connector terminals #1 and #2 must be approximately 1.8 V with the reading taken at the ground terminal.
