Next to solve the problem of engine oxygen sensor fault code, in the idle and did not find the engine intake, x100 pad2 tablet tool acceleration information and oxygen sensor information and other adverse circumstances. Simply carry out the relevant inspection and found that the air flow meter grille (Figure 4) has been cleaned. It seems that the problem can only be determined by driving.

In the original code to clear the road after the Xtool pad2 peogrammer test, the results in the high-speed road to test the user has described the fault. Normal acceleration overtaking the engine speed suddenly soared to 5 500 r / min and the speed did not significantly enhance the current time by observing the dynamic data and found that the phenomenon is not the clutch slip caused by the engine idling, but in the normal Acceleration process was originally maintained in the 4 block. Vehicle diagnosis.

With EZ500 HD the throttle opening increased, the transmission down to 3 block, in the 3 block to maintain a period of time to continue to accelerate the transmission will be reduced from 3 to 2 block. As the speed is relatively high (110 ~ 120 km / h) the actual transmission is relatively large, it will inevitably XTOOL EZ500 lead to the engine speed rose to 5 000 ~ 6 000 r / min. If the accelerator pedal is not released at this time, the speed of the transmission oil temperature is particularly fast (the torque converter TCC is unlocked), and the fault code of the oxygen sensor appears again. Repeated test, and ultimately determine the transmission of the gearshift function is too easy to achieve, and should not be down when the downshift.
