Benz nitrogen oxide sensor alarm and diesel Mercedes-Benz engine start deregulating

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. Replacing coal soot sensor is typically 2000 / month must be replaced once the two (upper and lower one), but not necessarily from the root of the problem (there might not be a problem soot particle sensor, but urea quality, oil or DPF problem). The same principle, primarily nitrogen-oxygen sensor fault code is also a system failure caused by a nitrogen oxide particle sensor (up and down each) or SCR (selective reducing catalytic converters, catalytic converters approximate effect, but more of a urea injection function). The same limit will trigger the engine starts. Alone with nitrogen-oxygen sensor may not be able to change fundamentally solve the problem, it is inevitable with the change after a period of time and must now change. Now offers soot sensor fault code, nitrogen oxygen sensor fault code solutions that solve soot particles sensor triggered by limiting the number of engine starts.
