Sentra 2.0L
- Turn ignition off. Disconnect distributor 2-pin harness connector (ignition coil connector). Turn ignition on. Measure voltage between ground and ignition coil harness connector terminal No. 7 (Green/White wire). If battery voltage exists, go to next step. If battery voltage does not exist, repair open or short circuit. See WIRING DIAGRAMS article.
- Turn ignition off. Disconnect distributor 6-pin harness connector. Check continuity between ground and distributor 6-pin harness connector terminal No. 2 (Black/Yellow wire). See Figure. Continuity should exist. Also, check circuit for short to voltage. Repair circuit as necessary. If circuit is okay, go to next step.
- Turn ignition off. Disconnect ECM harness connector. See Figure. Check continuity of Red/Green wire between distributor 6-pin harness connector terminal No. 1 and ECM harness connector terminal No. 35. See Figure. Also, check circuit for short to ground and short to voltage. Repair circuit as necessary. If circuit is okay, go to next step.
- Check ignition coil and power transistor. See IGNITION COIL and POWER TRANSISTOR
. If ignition coil and power transistor are okay, go to next step. If ignition coil and power transistor are not okay, replace distributor assembly.
- Remove distributor cap. Measure resistance of resistor (built into distributor cap) as shown in illustration. See Fig 1. Resistance should be 4-8 k/ohms at 77°F (25°C). If resistance is as specified, go to next step. If resistance is not as specified, replace distributor cap.
- No problem is indicated at this time. Problem may be intermittent. See INTERMITTENTS in TROUBLE SHOOTING - NO CODES article.
