Emergency SAIP Question.

My ‘17’s Secondary Air injection pump sees to have shit the bed. Codes P0418 and P2445.
It went into limp mode and I cleared the code, it’s gonna happen again. The dealer is 55 miles away and I’m dropping it off when they open on Monday.
Is there a way can keep it from going into Limp Mode to get it to the dealer?
I’m working out of state right now and don’t have access to many tools.

Edit: I cleared the code with my code scanner and drive the truck around for a bit. Started and restarted. Codes not coming back on and it’s not going into limp mode. Yet…..
The code came up yesterday afternoon. I checked it, cleared it and drove 50 miles on the highway without issue. Stopped at the store for some dinner and the code came back up when I started the truck again.

WTF? Is this standard for the SAIP when it starts to go?

 

I would use this trip as a point of reference now, or 50 miles before the codes come back. So, you can drive to the dealer and preemptively clear your codes 6 miles into your drive. So the remainder of the trip is trouble free. Only draw back is it probably wont be "ready" according to your basic OBD scan, if the dealer wants to see codes, you can probably drive around there and drop $5 of gas so the evap test is happy. By then you can roll in with codes blinking. Obviously I've done shit like this before. lol

Cycles are 2 engine starts before it comes back.. You cleared start drove 50 miles
assuming stop and start at store for food, that's your 2 cycle right there.

 

Thanks for the input.
The contract I’m on right now has my truck idling for long periods of time, maybe 20 very short drives a day, 115f temps and fine wind blown dust and lots of dirt road driving below 15mph (speed regs per the client). I’m working a gas pipeline consulting gig in the SoCal Mojave….
Wondering if the last few weeks of that has brought this issue on or if it’s totally unrelated.

Almost took the code scanner out of the toolbox before this job. Glad I didn’t.

 

If your out of warranty you might want to consider Hewitt by pass

 

5,000 miles left on the Toyota Care warranty, thankfully.

If there is a next time, is the Hewitt bypass a solid product?

 

That's great I've seen anywhere from 15 hun to 3k to fix/replace this stupid system

 

After doing some reading, could it be a relay going bad and not the pumps?
The pumps cycle (I think that’s what I’m hearing..) after I turn the ignition off.

Now if I can just find the relays…

 

I installed the Hewitt bypass on my 2007 last month. The kit was a bit of a pain to install the wiring harness on the passenger side bank because there’s a bunch of main wiring harness and harness anchoring loop in the way of where you need to reach in.

Plan on taking a lot of that harness anchoring crap off if you have large hands. Once I did that the passengers side air switching valve connector was able to be gently pried off with my left hand and a set of angled 11” needle nose pliers. Replacing the SAIP driver module is super easy.

I elected to order two Toyota OEM pressure sensors with wired connectors to plug into the Hewitt wiring harness rather than plug it into the stock air switching valves. That way I avoided the need to put the block off plates on the exhaust manifold, because I’m not risking touching an exhaust system that old and breaking a stud or nut.

Truck runs just fine, no more codes.

 

I've had the Hewitt bypass on my truck for about four years now no issues at all even passing state inspection

Hewitt is on the forum and have good customer service

 

Now I can’t get the code to pop again, of course. 200+ miles of mixed highway and city today. Lots of purposeful ignition use. WTF?Cancelling the dealer appt and just keeping the scantool in the console for now.
If I make it back home to Moab from SoCal without an issue I’ll just order the bypass kit and be done with it.

is the short ‘vacuum’ noise from the front right of the truck, at shutdown, the SAIP? If so, it’s cycling fine.

Also, y’all are awesome. Thanks for the help!
