Secondary air injection pump AIP

On my 2007 Tundra with 195K miles, I had the AIP valve stick, went into limp mode, but got home. I replaced both valves (left the original housing in place for an easier repair) which were rusted to crap. I poked holes in the rubber pump housings to drain the water (which there was), cleared the code and all was well. Now a month or two later with only a few hundred more miles, I have the CEL on and a code P0418, "Secondary Air Injection System Relay A Malfunction". Runs fine, but my wife was driving when it went into limp mode last time and I do not want to repeat that day.

Did some homework... there doesn't actually seem to be a relay that I can find. I assume a bad pump? Looks like I can get the pair for just over $100 shipped. They both had water, one much worse. I just hate to replace the wrong part.

 

There is a reason there is 6 pages of replies to this thread! The Secondary Air Injection System is a failure prone and inevitable on Tundras. We work with this issue everyday and happy to answer anyone questions about solutions. I have also included additional resources below and recent SAIS Threads.
