Diagnosis & Repair

WARNING: This page is about a different car, the 1995 Toyota Land Cruiser. However, it is still accessible from the selected car via links, so may be relevant.
  1. Disconnect distributor harness connector. Using ohmmeter, measure resistance between distributor connector terminals No. 2, 3 and 4. See Figure. Resistance should be 185-275 ohms (cold sensor) or 240-325 ohms (hot sensor).
  2. Replace distributor as needed. See procedures in the REMOVE/INSTALL/OVERHAUL article. If sensor is okay, inspect G1, G2 and G- circuits between ECM and distributor for open or short. See wiring diagram in the WIRING DIAGRAMS article. Repair as needed.
  3. If circuit is okay, check sensor-to-signal plate air gap. See the REMOVE/INSTALL/OVERHAUL article. If air gap is okay, replace ECM and retest. If air gap is not within specification, replace distributor.
