OEM Urea pressure sensors for common automotive parts

Product description

The vehicle is weak and urea consumption is normal. Fault phenomenon: vehicle fatigue, urea consumption is normal, emergency refueling can be found exhaust with a small number of white smoke mufflers. Fault analysis: The diagnostic instrument is used to read the fault code of engine emission exceeding the standard and no other faults. The urea nozzle was removed and the diagnostic instrument was used for injection examination. No abnormality was found. In the process of inspection, it was found that urea crystallization in the high-temperature catalytic tube was blocked seriously. Therefore, the exhaust elbow is removed and the gas belt is used to clean the carbon soot attached to the ceramic surface of the catalytic converter. Replacement of urea solution test fault disappeared. Low urea pressure and high urea consumption. Fault symptom: The meter fault indicator blinks frequently, and the fault code indicates that urea pressure is too low and urea consumption is too high. Failure analysis: The car urea tank upper leakage is serious, replaced the urea tank assembly, urea pump, after replacement, there is still urea solution leakage. The leak was found to be in the vent hole of the urea tank. Rule out the possibility of excessive urea solution, check the urea tank water heating valve. If the water heating valve is permanently damaged, replace it and rectify the fault. Professional manufacturing professional manufacturing engineering hydraulic sensor, injection molding machine special pressure transmitter, urea pressure sensor, brake pressure sensor, refrigerant pressure transmitter, gas high pressure sensor, etc.
