2005 Tundra 4.7 P2445 & P0418

All my research has pointed to the benefit of bypassing the pump. I've been in touch with Hewitt, but GD to get their bypass is $313 shipped for 2 modules. Has anyone built their own and would be willing to share how?

Last night I reset the codes. Today the pump worked, but had the shopvac sound. The cel shows the p2445 now as pending, but the hard fault is the p0418.

 

If you’re not in limp mode and running fine, drive it till you need a band-aid. Hewitt’s bypass works and is a lot cheaper for those who can’t/don’t want to tackle the repair.

 

Well, the truck was in limp mode intermittently . I'd have good power then I'd be struggling up a hill. So, I need to do something.. Lol

 

$313 is cheap insurance and piece of mind.

 

I had the shop vac sound on startup on my 2006. The truck never reached the point where it showed a CEL luckily. From what I read I knew there was a possibility that it would at some point. I purchased the Hewitt-Tech bypass kit and it took care of the problem. Did it before the CEL came on so I wouldn't have to install the block off plates either.

 

Well, I broke down and bought Hewitts bypass and proxy pack to cure my codes. The parts to fix would've run $400 +my time to install, and if I have the intake off, I would've wanted to do the starter too. So, for $313, it's good enough for now.
