Neutral Switch:






1. Disconnect the neutral switch connector.
2. Check switch continuity with an ohmmeter. With transmission in neutral, there should be continuity between switch terminals. With transmission in gear, there should be no continuity between switch terminals.
3. Reconnect neutral switch connector after testing or replacement.
