P2445 code appears while driving? 2006 Lexus GX470
What is your question?
I have a 2006 Lexus GX470. I started to get the P2445 code at startup, which would make sense if the secondary air injection pump was failing. I Learned this is caused by the secondary air injection pump. I installed a bypass that fixed the issue for a short while and then the code began appearing during my highway commute. Usually about 10-15 min in. I removed the bypass and I still get the code intermittently during driving. I though the ecu only looked for this during startup? When I get the code I pull over to check and erase the code with my code reader and then the issue disappears for the duration of that trip. What could be causing this and how can I fix? I sent the bypass unit back to the manufacturer to be tested and I have not heard back from them yet but the vehicle acts the same without it. I'm confused as to why the code would be thrown during a commute and how to fix it?
What makes this problem better or worse?
I have not been able to figure out the pattern as to when it occurs.
