Name: P1110-1.gif Views: 17676 Size: 21.8 KBThis fault conserns a fault in connection control hoses (see picture) in the solenoid valve or in the bypass valve.

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.

Enable criteria

  • 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.
