Diagnosis & Repair
WARNING: This page is about a different car, the 2002 Toyota Land Cruiser. However, it is still accessible from the selected car via links, so may be relevant.
- Crankshaft position sensor should be checked. Remove lower engine cover for access to crankshaft position sensor. Crankshaft position sensor is located at front of crankshaft, near crankshaft pulley. See Fig 2. Disconnect electrical connector for crankshaft position sensor.
- Manufacturer lists inspection procedure with crankshaft position sensor removed before checking the resistance. Remove bolt and crankshaft position sensor. Using ohmmeter, check resistance between electrical terminals on crankshaft position sensor. Resistance should be 1630-2740 ohms with sensor temperature of 14-122°F (-10-50°C) and 2065-3225 ohms with sensor temperature of 122-212°F (50-100°C). If resistance is within specification, go to next step. If resistance is not within specification, replace crankshaft position sensor. Reinstall crankshaft position sensor. Tighten crankshaft position sensor bolt to 58 INCH lbs. (6.6 N.m). Reinstall electrical connector and lower engine cover.
- Check for open and short in wiring harness and electrical connectors between crankshaft position sensor and ECM. See WIRING DIAGRAMS article. ECM is located behind glove box. See Figure. If wiring harness and electrical connectors are okay, go to next step. If wiring harness or electrical connector is defective, repair as necessary.
- Inspect crankshaft position sensor and teeth on signal plate located on the crankshaft for damage. If crankshaft position sensor or signal plate is damaged, replace components as necessary and reinstall crankshaft position sensor. Tighten crankshaft position sensor bolt to 58 INCH lbs. (6.6 N.m). Reinstall electrical connector and lower engine cover. If crankshaft position sensor and signal plate are okay, replace ECM. Reinstall crankshaft position sensor. Tighten crankshaft position sensor bolt to 58 INCH lbs. (6.6 N.m). Reinstall electrical connector and lower engine cover.
