GENERAL INFORMATION

Dependence of change of resistance of the sensor of temperature of the air coming to the engine on temperature
 

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

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