High quality automotive accessories gas high pressure sensor

Product description

The inlet pressure sensor can be measured as follows: Voltage Type Easy detection: Set a multimeter to DC voltage (10 or 20V) and measure the output voltage of the Map. At idle it is about 0.9V. If the signal voltage is lower than the normal value, there will be insufficient power, starting difficulty, high oil grid, fault light and other phenomena; 2, if the signal voltage is higher than the normal value, there will be insufficient power, exhaust liner fire, fault light and other phenomena. After the line fault is removed and the reference voltage provided by the ECU is correct, replace the sensor if it is abnormal. 3. Different detection frequency types: oscilloscope measurement is required. If the above method is adopted, it will be found that the measured voltage value does not change (about 2.4V). This is because it outputs a square wave, the engine speed changes, the intake manifold vacuum also changes, the amplitude of the square wave is unchanged (still 5V), but the square wave frequency changes; 4, if the frequency does not change, or there is no square wave, if the check is not a line fault, it is necessary to replace the sensor. Specializing in the manufacture of brake pressure transmitter, hydraulic pressure sensor, water pressure sensor, CNG/LPG high pressure sensor, refrigerant pressure sensor.
