Airflow Sensor: 2.6L
- Pull rubber boot back from airflow sensor connector. Backprobe sensor connector, and check terminal voltages. See Fig 1
. See AIRFLOW SENSOR TERMINAL VOLTAGES
table.
- If voltages are not correct, check wiring for open or short. If wiring is okay, check burn-off operation. See BURN-OFF OPERATION (2.6L) procedure. If ECU control of burn-off operation is okay but voltages are still incorrect, replace airflow sensor.
