6.2.5. Air stream sensor


The air stream sensor (models with the 6-cylinder engine till 1997 of release)

The sensor of a stream of air (shooter) is located in the airintaking channel.

The air stream sensor (models with the 4-cylinder engine of 1998 of release)


1. Remove and clear the sensor. Establish it into place.
2. Check giving of tension for the sensor.
All models with the four-cylinder engine and models with the six-cylinder engine of 1998 of release
3. Check tension between the MAF and GND plugs. On models where the socket of connection has three plugs, at the included ignition and the idle engine tension has to make 1,0–1,5 Volts. Idling tension has to make 1,5–5,0 Volts.
4. On models to the chetyrekhshtyrkovy socket of connection at the switched-off engine tension has to be close to zero. Idling it has to make 0,6–0,7 Volts (0,6–1,1 Volts on models of 1998 of release).
5. Lift the speed of operation of the engine and check that tension gradually increased approximately to 2 Volts.
Models with the six-cylinder engine of 1993-1997 of release
6. Disconnect an airintaking branch pipe from the sensor. Connect the voltmeter to the MAF and GND plugs of the socket of connection of the sensor. Include ignition. When the gate of the sensor is closed, tension has to make 4,0 Volts. When opening the gate tension has to change as follows:
a) the gate is open on 1/4 – 2,4 Volts
b) the gate is open on 1/2 – 1,6 Volts
c) the gate is open on 3/4 – 0,8 Volts
d) the gate is completely open – 0,4 Volts


1. Disconnect a wire of the minus plug of the accumulator.
2. Disconnect the socket of connection of the sensor, turn off fixing screws or bolts (shooters) and remove the sensor.
3. Installation is carried out upside-down removals.
