Fault code and EK data.

There are no changes to the Oxygen probe system fault codes.

There is one change that will be observed in the EK data. The EK72 value, Oxygen Probe Cell

Temperature, will be higher for the NXPK224455-56-57 oxygen probe. The normal value will be

820 °C. (1,508°F)

Refer to bulletin NEX-6101 or PPC-6001 for all fault codes and EK descriptions.
