What does this fault code mean?
The ECM continuously compares internal signals with each other, and the code is set when the comparison gives impermissible results with the engine running. The code may be a consequence of a fault related to the throttle. In that case the throttle fault should be repaired first, after which the code can be cleared.
Possible causes
- Fault related to the throttle, where this code is set as a result of that fault
- Poorly charged battery or corroded connection cables
- Damaged software in the ECM
- Damaged ECM
What you can do
- 1If another code relates to the throttle, repair that one first, because this code is then a consequence of it
- 2Check the battery charge and that the battery terminals and earth connections are tight and clean
- 3Check that the connectors at the battery and the ECM are tight and free from corrosion
- 4Clear the code and road test the car with the engine running to see whether it comes back
- 5If the fault comes back, have a workshop reload the software in the ECM. If that does not help, the module needs replacing
Symptoms you may notice5
- Malfunction indicator lamp (check engine) comes on or behaves abnormally
- The engine runs poorly and lacks power, especially when pulling away from a standstill
- The engine hesitates, surges or runs roughly during acceleration or deceleration
- The engine hesitates, surges or runs roughly at constant speed
- The problems may be present all the time or only now and then
What the fault can affect1
- Some internal signals in the ECM are replaced by default values
General guidance for car owners. Diagnosis on the car can point to a different cause.
