- Turn ignition off. Disconnect PCM connector. Inspect PCM connector for damaged or pushed out terminals. Repair as necessary. Perform TEST VER-2 . If PCM connector terminals are okay, go to next step.
- Using an external ohmmeter, check resistance of Orange wire between CKP sensor connector harness side and PCM connector terminal No. 7. If resistance is more than 5 ohms, repair open in Orange wire. Perform TEST VER-2.
- If resistance is less than 5 ohms, using an external ohmmeter, check resistance of Gray/Black wire between CKP sensor connector harness side and PCM connector terminal No. 24. If resistance is more than 5 ohms, repair open in Gray/Black wire. Perform TEST VER-2.
- If resistance is less than 5 ohms, put DRB in ohmmeter mode. Using DRB, check resistance on PCM connector terminal No. 7 (Orange wire). If resistance is less than 5 ohms, repair short to ground in Orange wire. Perform TEST VER-2.
- If resistance is more than 5 ohms, using DRB, check resistance on PCM connector terminal No. 24 (Gray/Black wire). If resistance is less than 5 ohms, repair short to ground in Gray/Black wire. Perform TEST VER-2. If resistance is more than 5 ohms, replace PCM. Perform TEST VER-2.
