What is an air switching valve?

The Secondary Air Injection System (AIR) Switching Valve is the computer controlled valve that controls the air injection into the exhaust system of the engine (this valve may be integral to the AIR pump). The PCM monitors the driver that activates the AIR pump for faults.

How does secondary air injection work?

Secondary air injection systems pump outside air into the exhaust stream so unburned fuel can be burned. The system injects the correct amount of air using inputs like coolant temperature, air temperature, and oxygen sensors.

Where is secondary air injection valve?

Secondary air valves are an integral part of the secondary air system. They are fitted between the secondary air pump (1) and exhaust manifold. They prevent pressure peaks in the exhaust flow from damaging the secondary air system and exhaust gas or condensate from entering the secondary air pump.

How does push starting damage the catalytic converter?

This is counterintuitive: Lean mixtures at high exhaust flow rates can damage a catalyst. The most common condition for this is the engine running out of fuel. But push starting could put the catalyst in the same condition. How this works it that the lean mixture does not burn in the cylinder but does in the catalyst if it is hot enough.
