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: Atmospheric pressure must exceed 72 kPa and the engine coolant and intake air temperatures must exceed -7 °C.

- Main relay voltage exceeding 10V. Engine speed below 3500 rpm. The inlet pressure drops rapidly by more than 3 kPa whereupon the accelerator pedal is fully released. The charge air pressure exceeds 120 kPa. The solenoid valve for the by-pass valve has been 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:


- The MAP sensor is used as a substitute value.


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: (See section Fault handling III, other emission-related components and functions for more information.)


- Type III.


Diagnostic help

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