Not sure what year Toyota started installing the secondary air pump to help with emission crap but it seems to have a high failure rate.
When it fails all kinds of codes get thrown and the pump is around $600-$700. Someone makes a bypass kit that @RichardB23 has but I think he still has problems.
I came across this today from Metal Tech and it implies the high failure rate is from the foam filter breaking down and being sucked into the pump causing it to fail.
Anyone have...
