Fault symptoms
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 -7°C.
|
|
-
|
Main relay voltage exceeding 10V. Engine speed over 3500 rpm. Intake pressure drops suddenly more than 3 kPa, after which the accelerator pedal is fully released. Charge air pressure exceeding 120 kPa. Bypass valve solenoid 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:
OK report:
|
-
|
Enable criteria fulfilled and amplitude below 1 kPa. Criteria must be fulfilled on three consecutive occasions during the same driving cycle.
|
