Urea pressure sensor is widely used in vehicles

Product description

The consumption of urea is less and less abnormal, indicating that there must be a problem in the post-treatment system; Second, urea consumption does not often affect the power of the vehicle, and even the serious speed limit. Some faults in the post-processing system are hidden. That is, faults exist in the post-processing system but do not meet the conditions for triggering the barrier code of the ECU. 1. Urea pump filter element is too dirty: the common filter element of urea pump is the liquid level sensor filter element, the liquid inlet filter element, the main filter element and the gas filter element (steam assisted urea pump unique). Which need to be replaced regularly is the main filter element and gas filter element, because urea injection did not pay attention to health or urea pump empty nozzle may enter part of the dust, a long time will cause the filter element blockage. Usually according to the requirements of urea pump filter replacement cycle is 50,000-60,000km, oil, steam filter replacement cycle is 100,000km or about a year, based on the actual requirements of the manufacturer. 2. Check whether the exhaust pipe is crystalline: The use of inferior diesel fuel, unqualified urea or post-treatment system failure may lead to crystallization of the exhaust pipe. Specializing in the manufacture of intake manifold absolute pressure sensor, common Rail Pressure Sensor, hydraulic pressure sensor, injection molding machine special Pressure Sensor, Urea Pressure Sensor, Brake Pressure Sensor, Refrigerant Pressure Sensor, etc.
