10.13.2. Sensor of a stream of air

Removal

Elements of the sensor of measurement of a stream of air and the case of a throttle of the 4-cylinder engine (the six-cylinder is similar)
A–fuel distributor;

B–case of the sensor of measurement of a stream of air;

C–collar of fastening of a rubber pipe;

D–throttle case


PERFORMANCE ORDER
1. Remove the distributor of fuel and a regulator of pressure of fuel.
2. Unscrew bolts and move aside an arm of draft of a throttle.
3. Disconnect the electric socket from the sensor of a stream of air.
4. Weaken a big collar of fastening of a rubber pipe and separate the throttle case from the lower part of the sensor of a stream of air.
5. Unscrew the nuts, fixing the sensor of a stream of air to rubber elements of fastening and arms (see drawing).
6. Remove the sensor of measurement of a stream of air from the case of a throttle and disconnect from it an air hose of turns of idling.
7. Unscrew screws and remove rubber laying from the case of the sensor of measurement of a stream of air. Note an arrangement of screws as they have various length.

Installation

PERFORMANCE ORDER
1. Installation is made in sequence, return to removal.
2. Start the engine and check that there are no leaks from earlier acting in film elements. Check and, if necessary, adjust turns of idling and the contents WITH in exhaust gases.
