8.5.6. Sensor of absolute pressure (four-cylinder engines)

GENERAL INFORMATION

Dependence of change of resistance of the sensor of temperature of air arriving in the engine on temperature
 

The sensor of absolute pressure in an inlet collector induces a signal from 4 In in the absence of vacuum to 0,5 In in the presence of vacuum.

PERFORMANCE ORDER
1. Include ignition, but do not start the engine and check tension from MAR-datchika which on a red wire there should be about 5 Century. 2. Remove a vacuum hose with MAR-datchika and instead of it connect the manual vacuum pump.
3. Disconnect the electric socket from MAR-datchika. Using the voltmeter, check the tension induced MAR-datchikom on a black/yellow wire. In the absence of vacuum tension should be about 4 In, and at vacuum creation it should decrease till 0,5 Century.
4. The sensor of temperature of air arriving in the engine is located in the case of the air filter. Resistance of the sensor changes depending on quantity postupayushche го in the air engine.
5. For check of the sensor of temperature of air arriving in the engine remove from the sensor the electric socket, include ignition, but do not start the engine.
6. Measure on the electric socket tension which should make 5 Century.
7. Connect an ohmmeter to contacts of the sensor of temperature of air arriving in the engine and at various temperatures measure resistance of the sensor.
