Co oznacza ten kod błędu?
The engine control module (ECM) calculates the engine torque in two ways from signals from the air mass meter, the throttle body and the intake pressure sensor, and compares the results. The code is set when the two calculations differ too much.
Możliwe przyczyny
- Air leak in the intake pipe, after the air mass meter and the throttle body
- Damaged throttle body
- Damaged engine temperature sensor
- Damaged flywheel sensor
- Damaged intake pipe pressure sensor
- Damaged engine control module (ECM)
Co możesz zrobić
- 1Check that the fuses are intact. Their location is in the owner's manual or on the fuse box cover.
- 2Check that the hoses in the intake system after the air mass meter and the throttle body are not cracked or loose, as a leak causes faults.
- 3Check the connectors to the throttle body and the pressure sensor for looseness, contact resistance and corrosion.
- 4If you have a diagnostic tool, read the airflow and intake pipe pressure in live data during a test drive, and check that the values agree with each other.
- 5If the fault remains, have a workshop check the throttle body and the sensors.
Objawy, które możesz zauważyć1
- No noticeable symptoms for the driver
Na co może wpływać usterka1
- Engine torque is limited, and the highest permitted level depends on the accelerator pedal position
