P0410 - SECONDARY AIR INJECTION SYSTEM MALFUNCTION
POST UPDATED IN June, 2023
Description of DTC code P0410 Generic
Diagnostic codeP0410 OBD2 refers to the emissions system. The air pump from the outside takes in and pumps air through 2 one-way check valves on each side of the exhaust, thus reducing emissions.
Approximately 90% of the time this fault code is established, the one-way check valves have ceased to function or are defective, allowing water naturally found in the exhaust to return to the pump.
If the weather is cold, or the temperature is very humid, the water may become more excessive. If this happens, the water partially fills the pump with air, which can freeze. When the Powertrain Control Module (PCM) commands the pump to turn on and the pump is frozen, it cannot rotate, this causes the circuit to overload and the fuse to explode.
