Oh, it's for a 2005 base deville,
Thanks Sub. I knowwhat the code definition is but not sure what is making it VERY intermittent. The blower motor runs every time but every so often sets the code. The cover is still on the blower and all of the hoses look good. What am I missing?P 0410 - Secondary AIR system. Supplies fresh air to the exhaust manifolds during cold start to quickly light off the cat.
