Charge Air Bypass Valve. Performance Problems.







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 condition for this diagnostic trouble code: Atmospheric pressure must exceed 72 kPa as well as coolant and intake air temperature must exceed -7 degree C.
- Main Relay Voltage exceeds 10 V. Engine speed below 3500 rpm. Intake pressure decreases rapidly by more than 3 kPa whereupon the accelerator pedal is fully released. 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:
- As a substitute value the intake pressure sensor and charge air temperature sensor are used.

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

- 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.
