Code P1412 MINI Description

The Air Injection (AIR) System refers to an emissions control system used by some vehicle manufacturers. It is often called secondary air injection, because air, more specifically oxygen, is injected into the exhaust manifold after start up. Vehicles start on a comparatively rich mixture to allow for smoother running conditions. However this has a large impact on exhaust gas emissions. A notable increase in hydrocarbon (HC) and carbon monoxide (CO) emissions is found under these rich start conditions. By injecting air in to the exhaust manifold the CO and HC can be oxidised. This reaction increases the temperature within the exhaust and the exhaust gas after treatment system i.e. catalytic converter can begin working earlier due to meeting its light off temperature.
The system consists of an air pump, one way check valve and associated pipework. The system operates for a predetermined time after start up. Normally this duration is approximately three minutes, when cold.
