Code p0410 THE SECOND AIR PUMP IS WORKING WHAT ELSE COULD IT BE

Posted / edited by AnonymousUser on : 12-11-2018

Answers :

About 90% of the time that this code is set, the one-way check valves have worn out or failed and allow water (which occurs naturally in the exhaust) back into the pump. In any cold climate, especially in climates with higher humidity, this water may be more excessive. The water partially fills the AIR pump, it can then freeze. When the PCM commands the pump on, if the pump is frozen it cannot turn, thus overloading the circuit and "popping" the fuse. Follow the link to read more
