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 fig. 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 a measuring instrument of a stream of air. Remove a sealing ring.
3. Weaken a collar, a fixing main air branch pipe by the right end of a measuring instrument of a stream of air.
4. Unscrew four bolts, fixing the air chamber to the throttle case. Raise the air chamber from the case of a throttle and in the basis of the air chamber disconnect a hose, then remove assembly air a chamber/measuring instrument of a stream of air.
5. Disconnect the electric socket from the sensor of provision of a butterfly valve (see fig. 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 sequence, return to removal.
2. On models with system of injection of Motronic M4.1 fuel before a 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 counter-clockwise before emergence of notable resistance and tighten fastening screws;
– at the moment of opening and the moment of closing of a butterfly valve from the sensor should be audible click;
– if necessary adjust position of the sensor of a butterfly valve so that when opening butterfly valve from the sensor click was audible.

3. On models with system of injection of Motronic M fuel 1.5 at installation of the sensor adjustment as it is possible to establish the sensor only in one situation is not required.
