Fault symptoms

•	Engine speed limited to 2200 rpm.

•	CHECK ENGINE.

•	Idling speed incorrect.

•	Cruise control not working.

On-Board Diagnostics

Type of diagnosis:

-	Continuous. But interrupted when fault criteria fulfilled and will not restart until next driving cycle.

Enable criteria:

-	Ignition in ON position.

Fault criteria:

-	Pulses from control module input for pedal position sensor 2 detected on control module input for pedal position sensor 1.

Dependents:

-

None.

System reaction to a fault:

-	Fuel shut-off at engine speeds above 2200 rpm. Throttle control goes into limp-home mode. Limp-home solenoid will be activated 5 times in succession each time the ignition is turned on until the fault has been rectified and the trouble codes cleared.

OK report:

-	Accelerator pedal has been depressed at some time and then fully released. 120 s has expired since then without fault criteria being fulfilled.

Fault handling: (For more information, see .)

-	CHECK ENGINE goes on immediately and can be turned off only by clearing the trouble codes.
