Hi,
I have a 2013 land cruiser with the 5.7 petrol in the US, and I'm getting a DTC for secondary air injection (P0419/$07E8 Secondary Air Injection System Control B Circuit). I am not getting a P0418 (SAIS Control A Circuit).
If the pump itself is bad, shouldn't I get both a and b circuit codes? Where are the relays?
This code came up coincident with removing the millimeter wave radar controller, doing some pinout testing on the connector, and reinstalling the system. To the best of my knowledge, I didn't damage any wires or fail to reconnect anything. A visual inspection of the work area doesn't show any broken or missing wires. I don't get how this could be related, but life experience tells me I probably did something unintentionally that caused this. Maybe I shorted something inadvertently and popped a fuse?
Radar cruise and PCS seem to be working as designed. I don't have any other DTCs. I don't have any noticeable drivability problems.
I've cleared codes three times and it always comes back after a few drive cycles (seems like three drive cycles, but I haven't been keeping exact track of it).
I searched 'mud and didn't find any results. I see a lot of reference to this code on Tundra 5.7 liter engines. I searched the FSM and there's lots of detailed troubleshooting info that I will use to dig into this, if I don't find a shortcut from you all.
Has anyone else seen this code? What was your resolution? Pump replacement? Bypass the system (Hewitt-Tech) - for offroad use only, of course?
Thanks in advance for anything you can tell me.
