| Boost pressure control pressure transducer, location | Mounted at rear on cylinder head of left cylinder bank |
| Boost pressure control pressure transducer, task | To produce modulated boost pressure for the vacuum cells depending on the PWM signal from the engine control unit. |
| Boost pressure control pressure transducer design | Plastic housing with coil for the battery voltage, resistance approx. 23 Ω, actuation by means of the PWM signal, frequency approx. 30 Hz |
| Boost pressure control pressure transducer, function | A valve plate operated by the coil armature increases the opening time to atmosphere as the duty cycle increased. As a result only a part of the boost pressure from connection 1 acts on the vacuum cells. |
