Test TC-2B - No Crank Reference Signal At Pcm
WARNING: This page is about a different car, the 1995 Dodge Dakota. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
For circuit and connector terminal identification, see CONNECTOR IDENTIFICATION . For wiring diagrams, see WIRING DIAGRAM section.
- Turn ignition off. Disconnect Powertrain Control Module (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 and PCM connector terminal No. 7. If resistance is more than 5 ohms, repair open Orange wire. Perform TEST VER-2.
- If resistance is less than 5 ohms, put scan tool in ohmmeter mode. Using scan tool, check resistance of PCM connector terminal No. 7 (Orange wire). If resistance is more than 5 ohms, replace PCM. Perform TEST VER-2. If resistance is less than 5 ohms, repair short to ground in Orange wire. Perform TEST VER-2.
