Q&A

The codes P0410 and P0460 are read when inputting my OBDII sensor unit under my steering wheel and are triggering my check engine light. I have read that the P0410 is the secondary air injection malfunction and probably just need to clean some air lines to fix the code. How do I locate and know which lines to clean? The second code P0460 is stated as the Fuel Level Sensor "A" Circuit Malfunction. If I understand correctly there are two fuel level sensors located on the driver and the passenger side underneath the rear seat cushion of the car. How can I know which sending unit to replace? If I only need to replace the "A" sensor then obviously I only want to buy and work on the "A" side of the vehicle. Thank you so much for your help.
