The Secondary Air Injection System Bypass Kit - Plug and Play!
The SAIS Bypass Kit - Plug and Play prevents operation of the SAIS at cold start thus letting you clear your related trouble codes, the CEL and Limp mode and installation made easy. Click on images for more details!
The bypass kit we recommend for most customers! If you don't want to splice or tap into your factory harness these kits are for you!
This Plug In version of the Original SAIS Bypass kit offers all the same features and benefits of the Original Wired Version but with super quick and labor saving Plug and Play Installation. All wiring connections except the starter relay connection are accomplished by the Plug and Play harness. Detailed Installation Instructions are easy to follow and include all needed wire colors and an easy to read wire diagram for proper installation. Like the wired version, these kits prevent operation of the secondary air injection system at cold start. By preventing the SAIS from operating many of the trouble codes, CEL and Limp mode that are associated with a SAIS failure will not return once cleared. The Plug and Play Harness provides a very clean factory looking installation that allows for the bypass module to still be hidden out of plain sight.
Here are the Common Trouble codes that the Standard Bpyass Kit can illiminate:1441, P1442, P1444, P1445, P2440, P2441, P2442, P2443, P2445*, P2447
For more information on trouble codes that Can and Cannot be cleared with the bypass kit alone... Please check our Trouble Codes Section and review the installation instructions.

More About the SAIS Bypass Kit
The bypass module is activated when the ignition is first switched to "ON" and any time it detects a 4-12V signal on the starter relay wire. The starter relay option is only available on the Original SAIS Bypass Modules! This option, when connected, ensures that the module actively prevents the SAIS from running on EVERY start. With the starter relay wire connected you can turn the ignition to "ON" for any period of time and the module will be active as soon as you crank the engine. Without the starter relay wire connection, you would need to turn the igntion back "Off" and then crank the vehicle to ensure the module is active or the system could operate and cause trouble codes and the CEL to come back on. Just install the kit with the starter relay wire connection and don't worry about having to start the engine as soon as you turn the key on! If anyone else drives the vehicle this is a Must!
The included No.2 Exhaust Valve Block-off Plates are an integral part of the bypass kit (images may not match the plates you receive for your specific engine). The block off plates are the only way to isolate the exhaust valves and the related pressure sensor(s) from the exhaust. By completely isolating the system from the exhaust the pressure sensors are prevented from causing valve stuck open trouble codes which are the main cause of limp mode when this system fails. Even though a system is bypass and should never run again, the Exhaust No.2 valves can still leak exhaust and cause future trouble. Installing the block off plates is the only way to prevent future valve trouble and limp mode. Again, it is just best to install and forget about it.
Works like promised. I first installed it incorrectly, called custumer service and they knew exactly what i had done wrong. Walked me thru it and problem fixed! Took me around 1 hr 45 min w the removal and install of bubus lol
A local Toyata dealership tried several times to fix this secondary air injection valve issue while it was under warranty but the problem kept reoccurring. The secondary air injection values and pumps were supposedly replaced three times but I continued to have all the associated flashing dash lights and codes. They ultimately told me they could not figure out why this was happening. They offered to replace a few electrical components that would not be covered by warranty and said this may or may not fix the problem. So, I said no thanks! I eventually stumbled upon this bypass kit for my tundra, and it was hands down the BEST money I've ever spent on this truck! Extremely fast shipping! Easy to install,and works as advertised! Thank you guys so much!!!!
I ordered this unit for my 2012 Tacoma 4.0L. I called and spoke to customer service to determine the exact kit that I would need and placed my order over the phone. She was very knowledgable and helpful. Everything arrived on time as promised. Installation was a bit of a chore because of the location one of the connections. It's behind the engine, against the firewall. Like another reviewer mentioned, the space to attach the block-off plates is really tight, but there are a few other connections that can be loosened in order to gain better access. In short, no codes after installation. This is a much better option than the $1200 - $2000 fix from the dealer.
Ordered the plug and play bypass kit for my 2008 Toyota Tundra 5.7, very easy to install. Great instructions, easy to follow. Great customer service, fast delivery! In total it only took me 30 minutes to install the bypass kit! Very happy with the results and definitely beats the $4230 the dealership wanted for parts and labor
Ordered for my 2012 Tundra 4.0L V6 but what I received first did not fit my truck. I was dreading having to go back to the dealership and pay ~$3k to fix this problem. I took a couple pictures and contacted customer service and was then express mailed a new harness to fit my truck! After I plugged those in and set up the starter relay I found out my block off plates were too small.
A quick email later I had the larger block off plates priority mailed to me.
I have now installed everything and the CEL has not returned. This coming from a guy who has spent zero time under the hood of a vehicle before this! I just want to thank everyone who helped me and genuinely cared about me being able to fix my truck.
Truly a life saver!
Your Truck had a different setup than we have seen on those in the past. I am glad we were able to get it taken care of for you.
I installed on my 2012 Tacoma Sport 4.0 and it solved the $3000 that haunts these trucks. Easy install in about an hour or so and great service. I sent them some pics that will hopefully help others with the install. I highly recommend.
i installed this product on my 2012 Tacoma 4.0 and it worked flawlessly! The instructions were spot on and I loved the customer service that comes with this company. I would not hesitate to order through this company again. The install took a bit longer for me, almost 2 hours, because I have large hands and had to remove some extra parts to loosen bolts for the block off plates. So far no CEL and no limp mode for my truck!
