2006 WRX, I just removed the secondary air pump to free up room in the engine bay (it has been out of service for the last 10 years and all the DTC codes have been deleted for it), and ever since I’ve done that I keep throwing P0457. I haven’t replaced the gas cap yet, but have cleared the code...

Hey guys, quick question. Popped the code for secondary air pump p2444. The pump was stuck on even after I turned the car off. For the moment I’ve got the pump unplugged so it doesn’t catch fire. But before I go and start tearing shit apart, is there a way to know if the valves are stuck open...
