What does this fault code mean?

The engine control module (ECM) sets this code when it blocks a requested rise in idle speed. It is a subsequent fault, meaning it appears as a result of a fault another trouble code test has already found. The underlying fault is the one to fix. This code has no separate fault-tracing of its own.

Possible causes

Consequence of a fault that another trouble code test has found, involving the clutch pedal, the impulse sensor, the speed signal or the engine temperature
Troubleshoot the other trouble code instead

What you can do

1Read out all trouble codes from the engine control module, since this code appears as a result of another fault
2If any code for the clutch pedal, the impulse sensor, the speed signal or the engine temperature is stored, fix that fault first
3Erase the code once the underlying fault is fixed, then test drive to see whether it returns
4If it returns although the other codes have been dealt with, have a workshop with diagnostic equipment determine what is blocking the idle speed
