Am I right that in this particular case all three ppo2 values are zero 
(e.g. no sensors at all)? I remember seeing that in some of the original 
OSTC memory dumps. Then it makes indeed sense to omit the ppo2 values. 
But if there is one or more non-zero values, I don't think we should 
omit just the zero ones.
