Engine must be cold. Posted by B Millar [Email] ![]() ![]() ![]() In Reply to: P0401, Secondary Air Injection Pump, tkell ![]() |
The pump only activates on a cold start. Usually the first start of the day. It's audible and moves a LOT of air.
You can replace the pump but the cause of pump failure is usually the back-flow valves on each cylinder bank. They fail and let exhaust moisture into the pump.
