October 30: LEMON manuals on a temporary server, it is slow and having issues, download the manuals you need! Later in November we will switch back to the fast server.

Intake Air Temperature Sensor

Disconnect airflow sensor connector. Check intake air temperature sensor by measuring resistance at terminals 2 and 4. Replace airflow sensor assembly if readings are not to specifications. See Fig 1 .
