What does this fault code mean?

The ECM continuously checks that the mass air flow sensor signal is plausible. The code is stored when the signal is wrong, and the fault here is a voltage that is too high. A fault on the swirl flap can also cause the code to be set. The results are that engine torque may be limited and a calculated air mass value is used.

Possible causes

If this code is set together with ECM-P029900, the cause is probably a leak in the hose or joint between the turbocharger and the intake valves
Camshaft in the wrong position
Damaged mass air flow sensor

What you can do

1Read and note the code, clear it and road test to see whether it returns
2Look for leaks: cracked hoses and loose clamps on the hoses and joints between the turbocharger and the intake pipe
3Check that the connector at the mass air flow sensor is fully engaged and free from corrosion
4With a multimeter, check that the signal wire to the sensor is not shorted to supply voltage
5If the fault remains, have a workshop check the camshaft position and the mass air flow sensor

Symptoms you may notice1

The car lacks power and runs poorly

What the fault can affect2

Engine torque may be limited
The control module uses a calculated air mass value in place of the sensor signal

General guidance for car owners. Diagnosis on the car can point to a different cause.
