The secondary air valve works in such a way as to maintain good emission values when the car is hot or even at a cold start. The air is pumped into the exhaust manifold via the secondary air valve, and the oxygen in this air brings about a chemical combustion whereby heat is generated.
The secondary air valve in a car acts as a back pressure valve and this is needed to complete the entire secondary air injection system. If your service centre suggests that you need to replace the secondary air valve in your car, don’t hesitate as it could negatively affect the running of the vehicle.
