WARNING: This page is about a different car, the 2002 Nissan Sentra, 2002 Infiniti G20, 2001 Nissan Sentra, and 2001 Infiniti G20. However, it is still accessible from the selected car via links, so may be relevant.
  1. With ignition off, disconnect transaxle harness connector. Measure resistance of shift solenoid valve "B" between transaxle harness connector terminal No. 1 and ground. Resistance should be 5-20 ohms. If resistance is as specified, go to step  3. If resistance is not as specified, go to next step.
  2. Remove valve body assembly. See appropriate SERVICING article. Check shift solenoid valve "B". See SHIFT SOLENOID VALVE "B"  under COMPONENT TESTS. Check transaxle harness and connectors for open or short. Repair as necessary. After repairs, go to next step.
  3. Check power source circuit. With ignition off, disconnect TCM harness connector. Check for open or short between transaxle harness connector terminal No. 1 and TCM terminal No. 12. Repair circuit as necessary. After repairs, go to next step.
  4. Road test and perform DTC CONFIRMATION PROCEDURE . If DTC is still present, recheck applicable TCM input/output signals. See PIN VOLTAGE TESTS . If any voltage measured is not as specified, check TCM connector terminals for damage or loose connection to harness connector. Repair as necessary.
