7.23. Sensor of provision of a butterfly valve

GENERAL INFORMATION

Unscrewing of the screw of fastening of the sensor of provision of a butterfly valve on the early SOHC models

Removal

SOHC MODELS

Detachment of the electric socket from the sensor of provision of a butterfly valve on the early SOHC models

PERFORMANCE ORDER
1. Remove a weight wire from the accumulator.
2. Disconnect the electric socket from the sensor of provision of a butterfly valve (see rice. A detachment of the electric socket from the sensor of provision of a butterfly valve on the early SOHC models).
3. Unscrew the screw of fastening of the sensor and take the sensor of provision of a butterfly valve from the throttle case.

DOHC MODELS

Detachment of the electric socket from the sensor of provision of a butterfly valve on the DOHC models

PERFORMANCE ORDER
1. Remove a weight wire from the accumulator.
2. Disconnect the electric socket from the air stream measuring instrument. Remove a sealing ring.
3. Weaken a collar, the fixing main air branch pipe by the right end of the measuring instrument of a stream of air.
4. Unscrew four bolts fixing an air chamber to the throttle case. Raise an air chamber from the case of a throttle and in the basis of an air chamber disconnect a hose, then remove assembly of an air chamber / measuring instrument of a stream of air.
5. Disconnect the electric socket from the sensor of provision of a butterfly valve (see rice. A detachment of the electric socket from the sensor of provision of a butterfly valve on the DOHC models).
6. Unscrew two screws and take the sensor of provision of a butterfly valve from the throttle case.

Installation

PERFORMANCE ORDER
1. Installation is made in the sequence, the return to removal.
2. On models with system of injection of M4.1 Motronic fuel before tightening of screws of fastening of the sensor of provision of a butterfly valve adjust position of the sensor as follows:

– turn the sensor case counterclockwise before emergence of notable resistance and tighten fastening screws;
– at the time of opening and the moment of closing of a butterfly valve from the sensor has to be heard click;
– if necessary adjust position of the sensor of a butterfly valve so that when opening a butterfly valve from the sensor the click was heard.

3. On models with system of injection of Motronic M fuel 1.5 at installation of the sensor adjustment as the sensor can be installed only in one situation is not required.
