| CHECK HARNESS BETWEEN ECM AND VARIABLE VALVE LIFT DIAGNOSIS OIL PRESSURE SWITCH RH. |
|
1) Warm up the engine. 2) Turn the ignition switch to OFF. 3) Disconnect the connectors from the ECM and variable valve lift diagnosis oil pressure switch RH. 4) Measure the resistance of harness between ECM and variable valve lift diagnosis oil pressure switch RH connector. Connector & terminal (B134) No. 31 — (E71) No. 1: |
| QUESTION | |
