Has anyone ever thrown a secondary air injection pump code it says I have a upward flow leak.... Could this be caused by not having those line attached to my intake tube. I get like two starts and it throws a code.

 

Which specific code?

Utah

 

lol my bad it P0411

 

P0411

90% chance crossed, disconnected vac lines or backwards check valve (1).



10% chance air pump has burned through itself (melted plastic impeller)
