Throttle body

REMOVAL

• Disconnect the battery.
• Remove the air filter housing (1) (Chapter Fuel Mixture, Air Filter Housing, page 12A-14).
• Disconnect:

• the throttle body connector (2),
• the fuel vapour recirculation hose (3) from the control solenoid valve.

• Remove:

• the mounting bolts (4),
• the throttle body.

INSTALLATION

• Refit in the reverse order of removal.
• Replace the throttle body gasket every time it is removed (use grease to ease installation).
• Tighten to the following torques:

• the throttle body bolts (1.3 daN.m),
• the air filter housing bolts (0.9 daN.m).

Connect the battery; carry out the necessary re-learns (see Electrical Equipment chapter).

• If the throttle body is replaced, use the diagnostic tool to reset the stop learning using command RZ005 "Learning".

When the ignition is switched on, the throttle body must perform a MIN and MAX stop learning cycle.

Use the diagnostic tool to check that the learning has been completed: ET051 "Throttle stop learning".

F4R or K4M

REMOVAL

• Disconnect the battery.
• Remove the air duct (1).

• Disconnect:

• the throttle body connector (2),
• the fuel vapour recirculation hose (3) from the control solenoid valve.

• Remove:

• the four mounting bolts (4) of the throttle body,
• the throttle body.

INSTALLATION

• Replace the throttle body gasket every time it is removed.
• Refit in the reverse order of removal.
• Tighten the throttle body mounting bolts to torque (1.3 daN.m), tightening in a crossed sequence.

Connect the battery; carry out the necessary re-learns (see Electrical Equipment chapter).

• If the throttle body is replaced, use the diagnostic tool to reset the stop learning using command RZ005 "Learning".

When the ignition is switched on, the throttle body must perform a MIN and MAX stop learning cycle.

Use the diagnostic tool to check that the learning has been completed: ET051 "Throttle stop learning".

F9Q

REMOVAL

• Disconnect:

• the battery,
• the boost pressure sensor (1).

• Loosen the clamp (2) of the air intake hose.
• Disconnect the air intake hose.
• Move the air intake hose aside.
• Disconnect the vacuum hose (3) from the brake booster.
• Remove:

• the three mounting bolts (4),
• the throttle body/brake booster assembly.

INSTALLATION

• Refit in the reverse order of removal.
• Replace the gasket.
• Tighten the throttle body mounting bolts to torque (0.8 daN.m).

Reconnect the battery; carry out the necessary adaptations (Chapter Electrical Equipment).
