What does this fault code mean?

The engine control module has registered a faulty reading from the mass air flow sensor. The cause may be poor contact, an air leak at the intake manifold or hoses, or wiring faults to the sensor. Sometimes the sensor itself is damaged.

Possible causes

Poor contact, contact resistance or oxidation at the connections
Air leak at the intake manifold or a hose
Break or short to ground in the signal wire
Signal wire shorted to supply voltage
Break or short in the sensor's ground or power supply
Damaged mass air flow sensor

What you can do

1With the ignition off, check the mass air flow sensor connector for looseness, contact resistance and oxidation
2Check the intake manifold, hoses and hose connections at the sensor for air leaks
3Check that the fuse for the sensor circuit is intact
4Use a multimeter to check that the signal wire has no break and no short to ground or supply voltage, moving the wiring as you measure
5If the fault returns although leaks and connectors are sound, have a workshop replace the mass air flow sensor

Symptoms you may notice3

Check engine lamp lights up or behaves abnormally
Car has poor performance or lacks power
Warning symbol and text message in the display

What the fault can affect2

A calculated air mass is used
Engine torque is limited
