| CHECK HARNESS BETWEEN ECM AND MASS AIR FLOW AND INTAKE AIR TEMPERATURE SENSOR CONNECTOR. |
|
1) Turn the ignition switch to OFF. 2) Disconnect the connector from ECM and the mass air flow and intake air temperature sensor. 3) Measure the resistance between ECM and chassis ground. Connector & terminal (B136) No. 9 — Chassis ground: |
| QUESTION | |
|
Is the resistance 1 MΩ or more? | |
| Yes | No |
