Co oznacza ten kod błędu?
When the engine control module tries to adapt the throttle unit, it notices that the throttle is blocked or that its movement is impeded. This is a component fault. The module may then cut the supply to the throttle motor, and the fault can lie in the throttle unit or in the wiring to it.
Możliwe przyczyny
- The throttle sticks or is blocked, for example by oil film or dust
- Contact resistance or oxidation in the connections between the engine control module and the throttle unit
- An open circuit, or a short to ground or supply voltage, in the wiring to the throttle motor
- The wires to the throttle motor have shorted to each other
- Damaged throttle unit
Co możesz zrobić
- 1Read the stored codes in the control module first. Codes for the throttle unit, the position sensor or the control module must be dealt with before this one
- 2Check that the fuses are intact
- 3With the ignition off, check that the throttle is not sticking and that nothing is blocking it. Clean the throttle unit if needed
- 4Check the connectors at the throttle unit and the engine control module for contact resistance and oxidation
- 5Look for breaks and shorts in the wiring to the throttle motor, and use a multimeter to confirm it has no contact with ground or supply voltage
- 6If the fault remains, have a workshop with diagnostic equipment decide whether the throttle unit needs replacing
Objawy, które możesz zauważyć2
- The malfunction indicator lamp lights up
- Poor performance
Na co może wpływać usterka1
- Depending on the fault, the control module may cut the supply to the throttle motor, and the throttle then tries to return to its spring-loaded position
