What does this fault code mean?

The engine control module calculates engine torque from signals from the mass air flow sensor, the throttle unit and the intake air pressure sensor, and compares the measured value with the requested value, which depends on the accelerator pedal position and engine speed. The fault is only checked in certain driving conditions. The code is often a consequence of another diagnostic function that has been close to its fault limit, so the root fault should be remedied first.

Possible causes

Air leak in the intake manifold after the mass air flow sensor and the throttle unit
Damaged throttle unit or mass air flow sensor
Damaged intake manifold air pressure sensor, or a damaged air pressure and air temperature sensor
Damaged engine or coolant temperature sensor, or damaged flywheel sensor
Damaged VVT unit or camshaft control valve, or damaged turbocharger components
Damaged engine control module (ECM)

What you can do

1Check whether other fault codes are stored for the engine control. This code is probably a consequence, so remedy the root fault first and then clear the code
2Check that the hoses after the mass air flow sensor and the throttle unit are secure and not leaking
3Check the connectors at the mass air flow sensor, the throttle unit and the air pressure sensor for looseness and oxidation
4If you have a diagnostic tool: compare measured and requested torque in live data during a test drive with steady throttle and at idle, and see whether they follow each other
5If the fault remains after these steps: have a workshop with diagnostic equipment check the sensors and components that are part of the torque calculation

Symptoms you may notice3

Jerky running
The engine lacks power, especially when pulling away from standstill
The engine hesitates, surges or runs jerkily during acceleration, deceleration or steady speed

What the fault can affect2

The cruise control switches off while the fault is active
Engine torque is limited, among other ways by fuel shut-off or the throttle position, and the maximum permitted torque depends on the accelerator pedal position
