| CHECK HARNESS BETWEEN MASS AIR FLOW AND INTAKE AIR TEMPERATURE SENSOR AND ECM CONNECTOR. |
|
1) Turn the ignition switch to OFF. 2) Measure the resistance of harness between mass air flow and intake air temperature sensor connector and engine ground. Connector & terminal (B3) No. 5 — Engine ground: |
| QUESTION | |
|
Is the resistance less than 5 Ω? | |
| Yes | No |
|
Replace the mass air flow and intake air temperature sensor. |
Repair the harness and connector. NOTE: In this case, repair the following item: • Open circuit in harness between mass air flow and intake air temperature sensor and ECM connector • Poor contact in mass air flow and intake air temperature sensor • Poor contact in ECM • Poor contact of joint connector |
