r_1_c32

I just got my Check Engine Light looked at by a shop earlier in the week. The error code was P2003 - Secondary Air Injection. I'm just wondering, what's the difference between the error code P2003 and the P0410 which also indicates Secondary Air Injection malfunctioning? Anyone has any idea? Thanks.

Totally unrelated btw

Yeah, it seems there are 2 different descriptions for the P2003 error code. When I looked at the OBD2 readout, it said "Secondary Air Injection", check out these threads also.
