2012 Tundra 4.6 CrewMax 190,000 miles

Anyone ever had any luck taking this off and simply cleaning it up and reinstalling?. Mine was stuck open and when I took it off and fiddle with it a little it closed. I cleaned it up and put it back together. The CEL light and TRAC control light didn't come back on. I wonder how long it will last? Thoughts?

Chances are it is going to happen again. Those things get loads of water in them and end up sticking open, like you experienced. You may have bought some time with the cleaning, but ultimately it’s bound to happen again. I applaud you for doing it though. Let us know how it turns out.

Honestly, the best thing to do is to bypass this stupid thing. All it does is blow extra air into the exhaust when you first start the engine to dilute the exhaust with air so that when the EPA sticks a probe in the tailpipe to measure the parts per million of pollution, the get a low enough reading to call the engine a low emissions engine. What a scam. You are emitting the same amount of pollution, just diluting it to make the EPA happy.

Just install a bypass kit and block off the valves so this system never turns on again and you will never get another check engine light because of this system. You can buy the kits from Hewitt for $200 or you can make your own for like $15. You will have to search this forum to find the original bypass system design which will tell you exactly how to make one.

Now that you have the system working, install the bypass kit and you will be good to go for the rest of the life of the truck.
