What does this fault code mean?
The control module continuously checks the signals from the mass air flow sensor and the intake air temperature sensor (bank 1). The fault code is set when the signal from the air temperature sensor is irregular. The sensor is built into the mass air flow sensor.
Possible causes
- Loose connections in the wiring
- Water in the air filter or air filter housing
- Damaged air temperature sensor inside the mass air flow sensor
What you can do
- 1Check that the relevant fuses are intact
- 2Read the diagnostic status and fault status for the code with the ignition on. Clear the code and road test the vehicle to see whether it returns
- 3Check that the connectors at the mass air flow sensor are firmly seated and that the wiring is not loose
- 4Check that the air filter and air filter housing are dry
- 5If the connectors and wiring are in order and the fault remains, have a workshop check or replace the mass air flow sensor
Symptoms you may notice1
- The Check engine light comes on or behaves abnormally
What the fault can affect1
- The control module uses a calculated value for the air temperature
