P1110

Fault symptoms

•	CHECK ENGINE.

On-Board Diagnostics

Type of diagnosis:

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

Enable criteria:

-	General conditions for this trouble code: When starting the engine, the atmospheric pressure must exceed 78 kPa and the engine coolant and intake air temperatures must exceed -7C.

-	Main relay voltage exceeding 10V. Engine speed above 3500 rpm. Intake pressure drops rapidly more than 3 kPa, after which the accelerator pedal is fully released. Charge air pressure exceeding 120 kPa. Bypass valve solenoid deactivated.

Fault criteria:

-	Charge air pressure pulsating at 14-18 Hz with amplitude exceeding 3 kPa. Criteria must be fulfilled on two separate occasions within 600 s during the same driving cycle.

Dependents:

-	P0106, P0107, P0108, P1105, P1106, P1107, P1108, P1530, P1531, P1532, P1631, P1632 and P1633.

System reaction to a fault:

-

None.

OK report:

-	Enable criteria fulfilled and amplitude below 1 kPa. Criteria must be fulfilled on three consecutive occasions during the same driving cycle.

Fault handling: (For more information, see .)

-

Type III.

Diagnostic help

Fault diagnosis concerns a fault in connecting control hoses, in the solenoid valve or the bypass valve.

Functions in the diagnostic tool related to the fault:

•	Diagnostic status for the diagnosis.

•	Activate output for bypass solenoid.
