A new pump, or simulator!

What signals the ECU, if the seconary Air Injection system isn't working?
H20 sensors, if running rich > Xtime throw code!
The pump only runs when the engine is cold, so the air & rich fuel mix is burnt in the exhaust manifold, so there's less Emission.

Not all newer cars have a Secondary Air Injection system (N/A), I need to suppress P0410.
How about a Powertuner Flash PCM delete P0410, but for how long?

If the pump is working, it's probably the down stream H20 sensor.

If you reset/clear code, you might be able to sneak it through an inspection with one ''Inc''
or unreadiness.

If 1996-Y2K, you can have 2-Inc test's to pass NC Federal Emission test.
