Vehicle sensors are input devices automotive computer system, which runs in the car information of various conditions, such as speed, temperature of various media, the engine operating conditions, etc., converted into electrical signals lost to the computer, so that the engine is in the best working condition. Many automotive sensors, sensor failure occurs when the judge should not only consider what the sensor itself automotive sensors, and should be considered a failure of the entire circuit. Therefore, when troubleshooting, check the sensor in addition to outside, but also check the relevant circuit wiring harness, connectors and sensors and electronic control units. Automotive Sensor past simply for the engine, has been extended to the chassis, body and electrical lighting the system. These systems use sensors have more than 100 kinds. In a wide variety of sensors in common: intake pressure sensor: automotive sensors offer to reflect changes in the intake manifold absolute pressure magnitude is to provide a reference to calculate the duration of the injection signal to the ECU (engine control unit); air flow meter: measurement of engine intake air quantity production of automotive sensors, fuel injection time available to ECU as a reference signal; a throttle position sensor: measuring throttle opening angle automotive sensors, as provided to the ECU off oil, control the fuel / air ratio, the ignition advance angle correction of the reference signal; crank position sensor: detects the crankshaft and the engine speed, as provided to the ECU determines the ignition timing and sequence of operations of the reference signal; oxygen sensor: detecting oxygen concentration in exhaust gas, as supplied to the ECU control the fuel / air ratio in the optimal value (theoretical value) near the reference signal; and automotive sensors wholesale | Shanghai Automotive Sensors | Xinfeng Xinfeng sensor provided by Xinxiang purification technology Limited.
