P0410 A Pathway to Emissions System Efficiency

I am beating my head on the wall with this P0410 error (Secondary Air Injection Pump) Light came on a week ago and I stopped driving as much. P0300 is almost always caused by a fault in the secondary ignition system, (spark plugs, wires, cap, rotor, and ignition coil). It has to do with the secondary valves being stuck open or shut in the intake manifold. Mine stick open giving the car a mean growl but it sounds like yours ...

The secondary air injection is 100% for emissions. It forces fresh air into the exhaust to speed up the catalyst operation when the car is first started. When a code P0410 is set, the PCM is not seeing the front oxygen sensor voltage drop sufficiently when the Air Pump is supposed to be adding ... P0410 is the trouble code for a problem with the secondary air system - not a vacuum leak. That's probably why the light is still on. The most ... Plugging in the AUTEL diagnostics tool revealed a P0410 fault code relating to secondary air injection, so I set about troubleshooting and fixing the problem. Venture - Air pump and p0410 & p0420 - First question are the codes p0410 & p0420 related in any way like will one cause the other etc. "Secondary Air" is an abbreviated term for the "Secondary Air Injection System". This system uses a separate air pump and a series of metal and rubber tubes.
