my truck (08, 4cyl, 5spd, base model, completely stock) has been throwing these codes. '
2441-air switching valve stuck closed
2445-air pump stuck off
they are both related to some pump that injects air into the exhaust when the engine is cold to lessen emissions--completely unnecessary for truck operation and has no effect on driveability. But....i need the truck to pass inspection and it will not b/c the light is on.
anyhow; does one of those issues "make" the other issue appear-- such as the "the switching valve stuck closed forces the pump to be off"?
all hoses/wires are hooked up, both issues appeared at the same time. the pump costs over $900, and the valve costs $300ish. i hate to "throw parts' at the problem, but i am not familiar with this system.
anyone have any insight?
