A lot of cars advocate the trouble that has encountered oxygen sensor, some has been encountered when new car, and mostly 4S inn does not wish to guarantee, need car advocate oneself spend money to change. Today we for the problem of sensor saying oxygen, say what oxygen sensor is first? Its installation is on vent-pipe, action is to detect the content of the oxygen in tail gas, if oxygen content is overmuch, the specification enters tolerance too much and fuel injection quantity is too little, oxygen is exhaustless, can adjust much fuel injection. If oxygen content is too little, explain fuel injection quantity is too much, oxygen is used not quite, can adjust little fuel injection. Because this oxygen sensor is fuel amends a the most important part, sky of hour fine adjustment is lighted than coming groove. Lantern show of trouble of the engine after it became bad is light, computer detects is the malfunction code about oxygen sensor.
Appeared oxygen sensor malfunction code, someone changes oxygen sensor, but malfunction code appears again after passing a few days, be problem of oxygen sensor quality bad? Actually a lot of circumstances fall, although appeared the malfunction code of oxygen sensor, but what have a problem truly is not certain it is oxygen sensor, the likelihood is other side has a problem, lamp of a few days of breakdown after was being changed shines again, the specification did not find the prime cause of breakdown. Fuel quality is for instance bad and indigestion carbon is too much cause combustion condition bad, can make oxygen sensor damages, occurrence malfunction code, among them fuel problem held great majority.
The gasoline of private and small-sized gas station is very cheap, go there the car that cheer advocate very much also, the oil that this has a few gas station among them is unqualified, contain lead and silicon to change content to wait overmuch, can bring about oxygen sensor even 3 yuan of catalysis are toxic attaint. Oxygen sensor just appears malfunction code, it is the surface only actually toxic, very slight still, if change right now the benzine of quality qualification, the toxicant that can eliminate the appearance is qualitative, make oxygen sensor returns to normal. Appeared so oxygen sensor must not change after malfunction code, should change above all fuel, breakdown as before if change again oxygen sensor. If gas problem is brought about, do not change benzine to change oxygen sensor only, after was being changed, how long can appear again too malfunction code. If carbon is accumulated to be brought about more too inside the crock,burn bad, a large number of oxygen sensor surface is adherent accumulating carbon, make tail gas cannot be entered, can make oxygen sensor damages as much, need keeps clear of first accumulate carbon, see oxygen sensor whether have trouble really again. Because the malfunction code of this oxygen sensor is not so easy maintenance, need thorough analysis, search breakdown germ, do not change at the beginning.
Somebody asks the malfunction code that had oxygen sensor, do not maintain can you still continue? Can continue, and opening a possibility also won't feel what to have unusual. But oily bad news can increase somewhat, discharge also can not amount to mark, so although can leave but also should maintain in time. Cheer at ordinary times must note fuel quality, a lot of breakdown may be fuel bad to cause, for instance idle when fast adventitious shake, those who accumulate carbon to increase is particularly fast, oxygen sensor and 3 yuan of catalytic attaint are waited a moment.
