GENERAL INFORMATION

Resistance check by the sensor of measurement of weight of a stream of air at engine warming up (V6 engine 1MZ-FE)
  

The sensor of measurement of weight of a stream of air is located in the inlet channel. Operation of the sensor is based on measurement сопротив the line of the warm conductor cooled by a stream of air.

PERFORMANCE ORDER
1. Disconnect the electric socket from the sensor and at inclusion of ignition check that on a black/orange wire there is a tension of the accumulator.

2. Connect the electric socket to the sensor of measurement of weight of a stream of air and connect the voltmeter to VG and VG-contacts. At the included ignition, but not working engine tension should be less, than 1,0 V.Posle of engine start tension should increase till 2 Century.

3. Check resistance between contacts of THA and Е2 the socket of the sensor of measurement of weight of a stream of air. Resistance of the sensor should change at engine warming up.
4. For removal by the sensor of measurement of weight of a stream of air disconnect from it the electric socket, remove a casing of the air filter, unscrew 4 bolts and remove the sensor.
