The secondary air intake system is part of a vehicle’s emissions control system and can sometimes trigger OBD2 code [P0420.](https://www.youtube.com/watch?v=G52AbdtuRTY) It works to support the function of the catalytic converter. The switching valves allow the air pump to pump air into the exhaust stream when an engine is cold, speeding up the process of warming the catalytic converter to burn unused fuel. We have permanent solution for the catalytic and the air injection pump for vehicles having dual exhaust. Diagnostic trouble codes P2442 and P2440 along with P0420 fix is available.
