Popular urea pressure sensor for air purification

Product description

If the urea pump Pressure Sensor is damaged, it will lead to the urea pump does not work, resulting in instrument alarm, discharge failure. Will lead to engine acceleration weakness, engine power torque limited problems. The urea pump sensor needs to be replaced separately to resolve this problem. Urea Pressure Sensor replacement method: the first step: read the fault code according to the diagnostic instrument, determine the fault point, pay attention to the failure of the functions related to building pressure and the failure of the components related to building pressure, such as nozzle, reverse valve, urea pump, heating relay, heating resistance wire, exhaust temperature sensor, urea tank temperature sensor. Step 2: If it is in a cold area, according to the fault code, first check the urea heating component to make sure the urea heating function is normal. Step 3: Check whether the urea pressure is normal, Step 4: if the pressure is successful, further check the nozzle, take it out, observe whether the injection is normal, whether the nozzle mechanical blockage is diagnosed. Step 5: Check the running condition of the vehicle. If the vehicle is running at low load most of the time, the exhaust temperature will be low and urea injection will not be released (minimum 200℃). Step 6: Further check the wiring harness to see if the wiring harness is reversed between the components. Step 7: Check calibration data if necessary. Specializing in the manufacture of urea pressure sensor, air compressor Pressure Transmitter, Water Pressure Sensor, common Rail Pressure Sensor, injection molding machine special pressure sensor, hydraulic pressure sensor, etc.
