 Throttle body (604)
• Contains the pedal position sensor (turned by the accelerator cable), the throttle motor and the throttle position sensor.
• Informs the control module of the driver's torque request.
• Turns the throttle to the position determined by the control module.

Limp-home solenoid (607)
• Fed by a relay, the limp-home solenoid (640) is governed by the control module.
• Mechanically connects the accelerator cable to the throttle spindle of a fault arises in the throttle body or any of

  its leads. The mechanism must be reset manually.

Charge air absolute pressure sensor (603)
• Informs the control module of the pressure level in front of the throttle.
• Used for determining density of air in front of the throttle. Dense air requires a smaller throttle angle.

Intake air temperature sensor (407)
• Informs the control module of the temperature in front of the throttle.
• Used for determining density of air in front of the throttle. Dense air requires a smaller throttle angle.

Manifold absolute pressure sensor (431)
• Informs the control module of the pressure in front of the throttle. • Used to correct the value from the mass air

  flow sensor during rapid load changes.

Turbo bypass control valve (605)
• Connects the bypass valve control in front of the throttle.
• When the accelerator pedal is released, the bypass valve control line is connected after the throttle.
   Prevents noise and varying charge pressure.

Mass air flow sensor (205)
• Sends frequency modulated information on the air mass flow to the control module.

• Acts as the main sensor for fuel injection.
