Codes 471, 717,711,and 712

471,717,711,712......I know what these codes mean and how to too trouble shoot each of them.... my question is does any one know why these codes ALWAYS occur together... I just can't figure it out, the root cause? Thanks for the help.

Thanks for the feedback. I'll be looking at the alternator on Monday.

Replacing all vacuum hoses and PCV valve will often reduce these nuisance 700 range codes. Experienced a 471 recently and after checking electrical system, found low alternator output and excessive alternator ripple voltage. Changed alternator and fault did not return.
Maybe just a coincidence, time will tell.
Have also noticed the faults become more frequent with engine age/hours.

Fact of the week
The dot-com bubble, a period of large and rapid investments in internet-based companies, peaked in 2000 and saw the Nasdaq Composite index rise by 579%. Then the bubble imploded. As the value of tech stocks plummeted, cash-strapped internet start-ups became worthless and collapsed.
