Removal

PERFORMANCE ORDER

1. Remove an air branch pipe of the case of a butterfly valve.

2. Disconnect the connection socket.

3. Turn off the fixing screw and uncover.

4. Remove an injector and consolidations.

Installation

Installation is carried out upside-down removals.

THE SENSOR OF TEMPERATURE OF ARRIVING AIR

The sensor of temperature is established in an injector cover.

Installation is carried out upside-down removals.

MODULE OF POSITIONING OF THE BUTTERFLY VALVE

Removal

PERFORMANCE ORDER

1. Remove an air branch pipe of the case of a butterfly valve.

2. Disconnect an accelerator rope.

3. Disconnect the socket of connection of the module.

4. Turn off fixing screws and remove the module.

Installation

Installation is carried out upside-down removals.

BUTTERFLY VALVE POTENTIOMETER

The potentiometer is located in the bottom section of a butterfly valve and is not subject to replacement.

Check

PERFORMANCE ORDER

Check, that resistance between plugs 1 and 5 (models with a mechanical transmission, fig. at the left) or 1 and 7 (models with an automatic transmission, fig. on the right) was between 520 and 1300 Ohm. When opening butterfly valve on one quarter resistance between plugs 1 and 2 should increase with 600 to 3500 Ohm, between plugs 1 and 4 (models with a mechanical transmission) or 1 and 6 (models with an automatic transmission) with 600 to 6600 Ohm.

SWITCH OF SYSTEM OF IDLING

The switch is a part of the module and is not subject to replacement. Remove the module of positioning of a butterfly valve.
