Possible Causes
- Electrical Cause
- Mechanical Cause
- Control Module Cavity
- Circuit reference I_A_IATS
- Monitor Description
- P0111-84 is set if the deviation between the reference temperature and the measured temperature from the air temperature sensor exceeds 20°C after an 8 hour soak period. This DTC is the minimum check therefore the temperature is reading ≥20°C lower than reference
- Open circuit in the signal line
- Short to ground in the signal line
- Offset temperature sensor (temperature sensor integrated within airflow sensor)
