P0102

Airflow Sensor Signal Line Open Circuit Or Short To Ground

P0102 - Air flow meter.: Short circuit to ground.

Possible causes:
1. Connector MS43 ECM C606, Airflow sensor C149.
2. Open circuit C606/1 (GW) - C149/2 (GW).
3. Short circuit C149/2 (GW) - Ground.
4. Airflow sensor.
5. Open circuit C149/3 (YG) - C578/11 (YG).
6. MS43 ECM.

1. Connector MS43 ECM C606, Airflow sensor C149.
CONNECTOR
