01273故障原因P0040 English definition:Oxygen sensorsignal is interchanged (1 row sensor1)/(2 row sensor1):o2sensorsignalsswapped(bank1,sensor1)/(bank2,sensor1It is used to measure the oxygen content in the engine exhaust to correct the amount of fuel injection, so that the engine can get the best air-fuel ratio.In the OBD fault code, you will often see the number of rows of oxygen sensors.Row 1 is the row in which cylinder 1 is located, and the remaining row is row 2.Regardless of the row, the first sensor always refers to the upstream oxygen sensor (before the catalyst box) and the second sensor always refers to the downstream oxygen sensor (after the catalyst box).The heating oxygen sensor monitor monitors whether the oxygen sensor signal response due to fuel conversion corresponds to the correct oxygen sensor row (bank).Possible causes for this fault code include oxygen sensor plug confusion, wiring confusion, etc.
