This code means that the computer has detected that the amount of air flowing into the exhaust system is not within the expected range. This can be caused by a number of problems, including:
- A faulty secondary air injection pump
- A leak in the secondary air injection system
- A faulty secondary air injection valve
- A faulty oxygen sensor
- A faulty computer
To diagnose this code, you will need to inspect the secondary air injection system for any leaks or damage. You will also need to check the operation of the secondary air injection pump and valve. If you are not comfortable performing these tests, you should take your vehicle to a qualified mechanic.
