2010 Tacoma, 2wd, manual trans, 2.7L 4cyl
In response to P2441(secondary air switching valve stuck closed) I have replaced every single component in that system:
Secondary air switching valve (ASV)
Secondary air injection pump (AIP)
Hose connecting AIP to ASV
Manifold absolute pressure sensor (MAP)
Hose connecting ASV to MAP
In addition, I have bench tested the ASV, found the solenoid to be fully responsive to input voltage; the reed valve is clean and moves freely. Attaching a test lamp to the ASV switching power line shows that the ASV is energized during cold starts, concurrent with AIP operation which is audibly running. I have verified continuity at the ASV electrical connector.
Still I get p2441, 2 codes, 1 pending. It comes back repeatedly after clearing the code with code reader. This is interfering with my ability to register my vehicle.
