What causes P0410 code?
Code P0410 is the result of the Engine Control Module (ECM) indicating a malfunctioning Secondary Air Injection System. This happens when the O2 sensor does not accurately detect the changes in the O2 level of the exhaust while the air injection system is functioning.
How do you fix a secondary air injection system malfunction?
- Replace both the air pumps and the one-way check valve.
- Try and clean the air pump and test it. The one-way air check valve must be replaced as well.
