If you've got a Toyota or Lexus 2004-2012 with a 4.7L or 5.7L engine, you may be aware of the issues with the AIP/Secondary Air Induction System failures, and the rather expensive dealer costs to get this repaired. There are a number of choices available outside of the dealer fix that might be worth considering. One very popular method is a set of DIY instructions. With some inexpensive parts and a bit of effort, you can easily modify your car to get the codes cleared and back up and running again. Plenty of information is available online regarding this method.
Another choice, which is also very popular, is to purchase a module that requires cutting and splicing into your factory wiring harness. It takes some soldering skills, but the module comes as a complete kit with full instructions. Definitely a bit easier than the DIY method, but it still requires some skills and specialized equipment to get it installed.
What I’m offering is a very simple plug-and-play solution. It requires ZERO modification to your existing wiring, and simply plugs in place right at the MAF (Mass Air Flow) sensor. If you’d ever find the need to remove it, well, it comes out as quickly as it goes in – a few seconds is all it takes to get the module in place. Again, complete instructions come with the kit.
Both available kits include a set of block-off plates, which are required to be installed in the system to prevent hot exhaust gasses from reaching the air injection pump(s). If you do decide to go the DIY route, feel free to contact me, I’d be happy to sell you a set of block-off plates if you need them.
All three methods above are considerably less than the dealer repair, but keep in mind that bypassing mandated emissions is illegal on public roads.
The module I’m selling was developed by a friend that had this issue with and 05' Tundra. After a bit of research, he realized that he could do a much better job than any solution that required cutting and modifying a factory wiring harness. After a few months of testing, the module was complete and ready to sell. It’s been installed on quite a few vehicles without issue, and it works exactly as designed – no more CEL codes, no more limp mode. Keep in mind that not all problems with the AIP system can be fixed by any of these kits – only the following codes are handled:
ADDRESSES THE FOLLOWING CEL (Check Engine Light) CODES:
P1441 – Secondary Air Injection System Switching Valve No 2 Stuck Open Bank 1
P1442 - Secondary Air Injection System Switching Valve No 2 Stuck Closed Bank 1
P1444 - Secondary Air Injection System Switching Valve No 2 Stuck Open Bank 2
P1445 - Secondary Air Injection System Switching Valve No 2 Stuck Closed Bank 2
P2440 - Secondary Air Injection System Switching Valve Stuck Open Bank 1
P2441 - Secondary Air Injection System Switching Valve Stuck Closed Bank 1
P2442 - Secondary Air Injection System Switching Valve Stuck Open Bank 2
P2443 - Secondary Air Injection System Switching Valve Stuck Closed Bank 2
P2444 - Secondary Air Injection System Switching Pump Stuck ON Bank 1
P2445 - Secondary Air Injection System Switching Pump Stuck OFF Bank 1
P2446 - Secondary Air Injection System Switching Pump Stuck ON Bank 2
P2447 - Secondary Air Injection System Switching Pump Stuck OFF Bank 2
My kit comes complete with the plug-and-play module, two block-off plates, and complete instructions. Because of the differences in the block-offs, two kits are available – one for the 4.7L engine, one for the 5.7L engine. Both are available on eBay:
4.7->http://www.ebay.com/itm/151499497332?ssPageName=STRK:MESELX:IT&_trksid=p3984.m1555.l2649
5.7->http://www.ebay.com/itm/151681454665?ssPageName=STRK:MESELX:IT&_trksid=p3984.m1555.l2649
