| CHECK HARNESS BETWEEN ECM, MASS AIR FLOW AND INTAKE AIR TEMPERATURE SENSOR CONNECTORS. |
|
1) Turn the ignition switch to OFF. 2) Disconnect the connector from the 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 |
