- Raise one rear wheel off the ground and secure vehicle. Release parking brake and place transmission in Neutral. Disconnect wiring connector from EFI ECU, located behind glove box.
- Attach ohmmeter positive lead to connector terminal and negative lead to ground. See Fig 3. Ensure ohmmeter probe is inserted from rear side of connector. Turn rear wheel and monitor ohmmeter. Ohmmeter needle should deflect consistently.
