Checking connectors and wiring




- Ignition off.
Check the engine speed (RPM) sensor connector. Check for contact resistance and oxidation.
Check the signal cable between:
- engine speed (RPM) sensor terminal #1 and engine control module (ECM) terminal #A48 (#A48)
- engine speed (RPM) sensor terminal #2 and engine control module (ECM) terminal #A66 (#B6).
Check for an open-circuit. Check for a short-circuit to ground. Check for a short-circuit to supply voltage.
Check the carrier plate, search for damage and other defects.
Remedy as necessary.
