5TH Position Switch
- Turn ignition off. Disconnect 5th position switch 2-pin harness connector located on side of transmission housing. Check continuity between ground and Black wire of 5th position switch 2-pin harness connector. Continuity should exist. If continuity exists, go to next step. If continuity does not exist, check harness and connectors between switch and ground.
- Disconnect ECM harness connector. Check continuity between ECM terminal No. 7 (Yellow/Blue wire) and 5th position switch 2-pin harness connector Yellow/Blue wire. Continuity should exist. If continuity exists, go to next step. If continuity does not exist, check harness and connectors between ECM and switch.
- With transmission in 5th gear, ensure continuity exists at 5th position switch connector. Replace switch if necessary. If switch is okay, disconnect and inspect ECM, harness, and connectors for pushed-out, bent, damaged or corroded terminals. Repair harness or connectors as necessary.
