Codes P1412 P1415
Speaking of the Secondary Air Injection, how I do I know if its the solenoid or the pump. I have codes P1412 P1415. The pump isnt ever on, so how could I test the pump before I spend 150+ on used or new one? Any ideas, or just start w/the solenoid first 28 bucks. thanks

From RAVE:
The ECM checks the engine coolant temperature when the engine is started in addition to the elapsed time since the
engine was last started. The engine coolant temperature must be below 55
engine was last started. The engine coolant temperature must be below 55
°C (131°F) for the SAI pump to run.
NOTE: The ambient air temperature must also be above 8
°C (46°F) for the SAI pump to run.
Also, depending on the long term 'modelled' ambient temperature determined by the ECM, the minimum elapsed time
required since the last engine start can be up to 8.25 hours. The period of time that the SAI pump runs for depends
on the starting temperature of the engine and varies from approximately 96 seconds at 8

So depending on your local conditions, pump may not run. Would think failed pump might show up on both banks for fuel intake.
