Well...I recently have been throwing the code P2432. Research shows this is Secondary Air Injection System Pressure circuit low. What are some steps to test the Secondary Air Checkvalve?

This code is a fault in the Secondary Air Pressure sensor circuit or the 5v Ref circuit for the pressure sensors. You need to check the pressure sensor circuits, terminals and see if you can find any issues. IF not, then test the wiring for continuity. IF all that tests out, then you likely need a new solenoid valve/pressure sensor assembly.

Thanks for the info rshadd.
Is the pressure sensor part of the check valve assembly or the in the blower assembly? I saw the post about the block off plug, I'll go that route, due to cost, if any of the components need replacing.

I plan on eliminating the system all together. I only have 26K on my 2010 Canyon and its giving me the 2432 and 0411 code already. If I install the block off plate on the intake manifold do I need to re-flash my computer? I would think that the computer would recognize that the system has been eliminated when its not receiving a signal from the sensor, but that would keep my engine light on.

At 26k the dealer should replace it.
