| CHECK HARNESS BETWEEN ECM AND MASS AIR FLOW AND INTAKE AIR TEMPERATURE SENSOR CONNECTOR. |
|
1) Turn the ignition switch to OFF. 2) Disconnect the connectors from ECM and mass air flow and intake air temperature sensor. 3) Measure the resistance between ECM connector and chassis ground. Connector & terminal (B134) No. 53 — Chassis ground: |
| QUESTION | |
|
Is the resistance 1 MΩ or more? | |
| Yes | No |
|
Replace the mass air flow and intake air temperature sensor. |
Repair the ground short circuit of harness between ECM connector and the mass air flow and intake air temperature sensor connector. |
