Intermittent Fault
- Ignition off.
Check the control module and transmission output speed sensor connectors. Check for contact resistance and oxidation according to CONTACT RESISTANCE AND OXIDATION .
Check the wiring between control module terminal #A57 (#A57) and transmission output speed sensor connector terminal #A4. Check the wiring between control module terminal #A39 (#A39) and transmission output speed sensor connector terminal #A3. Check for an intermittent open-circuit according to OPEN-CIRCUIT, 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 supply voltage according to SHORT-CIRCUIT TO SUPPLY VOLTAGE, INTERMITTENT FAULTS .
Remedy as necessary.
