Diagnostic help

The mass air flow sensor is sending pulses to the control module but the frequency is too low. Consequently, the sensor is powered and is in contact with the control module input.

In most cases, the trouble code indicates an internal fault in the sensor but a major leak between the sensor and the throttle, i.e. a disconnected sensor, can also generate it.

Functions in the diagnostic tool related to the fault are:

• Diagnostic status for the diagnosis.
• Mass air flow sensor value, unit g/s.
• Air mass deviation from calculated, unit %.
