What does the secondary air pump do VW?
An emissions component, that is part of the Secondary Air Injection system, which is responsible for Pumping clean Air into the vehicle’s exhaust stream to promote a cleaner and more complete burn before the fumes exit the tailpipe.
Can I drive without secondary air injection?
You will be fine driving to work in the morning. You will get or already have a CEL for hose being disconnected. The pump only runs for a minute or so on cold start to help burn exhaust gases and heat up the O2 sensor. The reason for the brown color is most likely due to rust from condensation in the pump.
What is code P2431?
secondary air injection system
What the P2431 code means. The secondary air injection system is used to add air into the exhaust to reduce vehicle emissions. When the the incorrect flow is detected, the electronic control unit (ECU) detects this fault and sets the P2431 code. This code causes the Check Engine Light to be illuminated on the dashboard …
What would be a concern if the SAI one-way check valve was stuck open?
If a P2442 code comes up, a one-way check valve is stuck open in the secondary air injection system, causing too much airflow into the exhaust and allowing hot exhaust gas to travel back into the pump. If the PCM receives a voltage reading of more than 10% of the allowed amount the P2442 code will be stored.
What is the OBD-II trouble code p2432?
OBD-II trouble code P2432 and related codes P2430, P2431, P2433, and P2434 are associated with the secondary air injection system air flow/pressure sensor circuit bank 1.

When to set the p2432 air flow sensor circuit Bank 1?
When the PCM detects voltage or resistance within the secondary air injection system air flow/pressure sensor circuit bank 1, that is too low, below the normal range threshold, code P2432 will be set and the check engine light may be illuminated.
