Diagnostic Test Procedure

  1. Disconnect negative battery cable. Disconnect EOT sensor connector. Disconnect the ECM connector EM80. Measure resistance between EOT sensor harness connector terminal No. 1 and ECM harness connector EM80 terminal 15. Is resistance greater than 5 ohms? If yes, repair high resistance between EOT sensor harness connector terminal No. 1 and ECM harness connector EM80 terminal 15. If no, go to next step.
  2. Reconnect negative battery cable. Turn ignition on. Measure voltage between EOT sensor harness connector terminal No. 1 and ground. Is voltage greater than 1 volt? If yes, repair short to voltage. If no, go to next step.
  3. Turn ignition off. Measure resistance between EOT sensor harness connector terminal No. 1 and ground. Is resistance less than 10,000 ohms? If yes, repair short to ground. If no, go to next step.
  4. Measure resistance between EOT sensor harness connector terminal No. 2 and ground. Is resistance greater than 5 ohms? If yes, repair high resistance between EOT sensor harness connector terminal No. 2 and ground. This circuit includes harness splices, PIS1 and EMS2, and the ECM. If no, install a new EOT sensor.
