Replace the oxygen sensor Benz nitrogen / oxygen sensor a replacement Mercedes nitrogen lifetime guarantee / W164 ..

US regulatory Mercedes soot sensor fault lights, alarm trigger urea light, limiting the number of engine starts. Soot particle sensor failure is generally caused by soot particulate filter, soot particle filter DPF (also known as trap soot particles, soot particle filter, carbon particulate converter) main function is to filter, store and combustion engine soot particles produced (mainly composed of carbon), and remove sulfur dioxide. And generating HC, CO, and other emissions. This process and the exhaust gas resulting from soot sensor monitors and test results, timely feedback to the ECU to adjust the combustion temperature and regeneration process (somewhat similar to the canister). Soot sensor through (CAT), under (DPF) temperature sensors and pressure sensors swim judgment, this process should have 99% of the soot particles is reduced. If the temperature, pressure normal while reducing soot particles of non-compliance, ECU fault codes recorded by the test results soot sensor. The fault is that DPF is a problem sulfur pollution or sensors. If there is no investigation can not solve the problem by replacing a single sensor. But no matter what factors cause soot particle sensor fault code will directly result in urea fault alarm lights, engine start trigger limit. The same principle, Mercedes nitrogen oxygen sensor fault code also largely (but more a function of urea injection Selective Reduction of catalytic converters, catalytic converters approximate effectiveness) system failure caused by a Mercedes-Benz nitrogen oxide sensor (up and down each) or SCR , the same limit will trigger the engine starts. Replace the oxygen sensor Benz nitrogen alone can not solve the problem is not necessarily inevitable with the change after a period of time and must now change. Mercedes-Benz now offers the soot sensor fault code, Mercedes-Benz oxygen sensor fault code nitrogen solutions (decoder chip), the number of one-time settlement of the engine start-Benz W166 and W164 limit nitrogen oxide sensor triggered, the chip can be removed directly coupled nitrogen oxide sensor Fuses, disable nitrogen oxygen sensor system working. Nitrogen solve the problem of frequent replacement of the oxygen sensor. Prices please call for inquiry Chang Road, Shenzhen Science and Technology Co., Ltd.
