B1702 Code

The B1702 Code is meaningful and you should get the meaning of the code if you wish to solve the problem by yourself. Deactivation of cylinders is attained by discharging a synchronizer pin that usually interlocks the cam follower and rocker arms. The B1702 code solves the synchronizer pin which is unconfined using hydraulic pressure which is controlled by a dedicated solenoid. The catalytic converter has an oxygen sensor what is found in front and behind of the catalytic converter. When the vehicle is, hot and it is running in closed loop mode for long time, the upstream oxygen sensor waveform reading should vary.
