    Hey guys, I have a 2016 tacoma with the 2.7lt engine. My check engine light is on and is reading the codes p2445 and P2441 indicating the secondary air injection pump. Was wonder if you could help direct to me to the relay or the fuse for the pump. I want to start small before I replace the pump. Thank you! Oh also I reset the check engine light and it comes on every like 2 or 2 and a half days.

    @Taylorl67 The codes you are tripping are both for the Bank #1 Air Switching Valve. On your '16 Tacoma 2.7L it is located on the passenger side of the engine right off the valve cover. The Secondary Air Injection is failure prone and you can spend all day reading horror stories of owners trying to address. The question is not "If" it will fail but "When" it will fail. If you have any questions do not hesitate to reach out, DM or give us a call.

    @hiPSI I have been in communication with moderators about becoming an official vendor. They have encouraged me to continue engaging with the community and as my interactions increase will consider vendor status. The moderator have advised me not to spam with products. I took this advice seriously and as you will see my thread replies focus on educating and adding value, majority include links to other threads that provide additional information about the failure prone system. If you feel my post have violated any forum policies please let me know.
