codes, shown as below.

Tip: In the process of diagnosis, if the device shows “System is OK” or “No Trouble Code”, it means there is no related trouble
code stored in ECU or some troubles are not under the control of ECU, most of these troubles are mechanical system troubles
or executive circuit troubles, it is also possible that signal of the sensor may bias within limits, which can be judged in Live Data.
