P1263

Fault symptom

•	Engine stalls.

On-Board Diagnostics

Type of diagnosis:

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

Enable criteria: (Conditions that must be fulfilled before the diagnosis can be performed.)

-	Engine running for at least 5 s. No vehicle speed.

Fault criteria: (After enable criteria have been fulfilled, the diagnosis checks whether fault criteria are fulfilled.)

-	Throttle motor is receiving 100% PWM in closing direction.

Dependents: (Occasionally after fault criteria have been fulfilled, a number of other diagnostics must report OK before the trouble code can finally be generated.)

-

None.

System reaction to a fault: (After fault criteria have been fulfilled, certain measures will occasionally be taken.)

-	Fuel shut-off

OK report: (The diagnosis can be included as a dependent for another diagnosis and must therefore report OK even if it is continuous. The OK report is also used in fault handling to decrement the fault counter.)

-	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: (See “Fault diagnosis, general” for more information.)

-	Type III. CHECK ENGINE does not go on.

Diagnostic help

This trouble code does not indicate a fault but is for information only. Avoid touching the throttle arm. If it is necessary to increase the engine speed while working on the engine, the throttle arm must be rotated instead.
