Hva betyr feilkoden?
Although the code is titled signal too low, it is stored when the ECM, while adapting the throttle unit, finds that the basic conditions for adaptation were not met. Other stored fault codes may be what stops the adaptation, so they should be remedied first. The code therefore concerns the conditions for adaptation rather than the signal itself.
Mulige årsaker
- The adaptation was attempted in the wrong ignition and engine state, where the engine must be off
- The accelerator pedal was not fully released during the adaptation
- The car was not standing still during the adaptation
- The throttle sticks or is blocked by oil film or dust
- Contact resistance or oxidation between the ECM and the throttle unit
- A damaged throttle unit
Hva du kan gjøre
- 1Read the fault codes and deal first with any that are present, as they can stop the adaptation from being carried out
- 2Adaptation requires the engine off, the accelerator pedal released and the car stationary. If any of these was not met, that may be the reason
- 3Check the connectors between the ECM and the throttle unit: are they secure, and is there oxidation or corrosion
- 4Check that the throttle is not blocked by any object and not sticking. Clean as needed
- 5If you have a diagnostic tool: check in the parameters whether the adaptation of the throttle unit went through, meaning it shows OK. The adaptation itself is carried out by a workshop
- 6If the fault remains, the throttle unit may be damaged. A new unit must be adapted, which a workshop does
Symptomer du kan merke1
- Poorer engine performance
Hva feilen kan påvirke3
- The adaptation is cancelled
- The ECM cuts power to the throttle motor, and the throttle goes to its return position
- Only if a new ECM has been fitted to the car, one that has never adapted the throttle unit before, can the ECM use a reversible fuel shut-off
