2005 Chevrolet Trailblazer Q&A
2005 Chevrolet Trailblazer Question: 05 Trailblazer engine light on
Code P0410 on your 2005 Chevrolet Trailblazer relates to the secondary air injection system. This system pumps fresh air into the exhaust manifold during engine warm-up to help burn excess fuel and get the catalytic converter up to operatimg temperature faster. P0410 means the system is not working. The pump may have failed, it is located under the front of the engine. There could also be a problem with a check valve or related plumbing. The system should be properly diagnosed before any repairs are attempted. - Russ
