2007 Tundra 5.7/ P0418

[mjk1967]

Took a 07 Tundra for a test ride today. As clean as an 07 can get in MN, 1 owner, 120k.

CEL on, stopped in at O'reillys. Read the code. Read about it a bit, before returning to dealer. Seems like there may be multiple ways to fix it, including some bypass.

What would be the ranges for getting it fixed, if I was to take it in to a mechanic ? Assuming labor here is usually 150/per/

The dealer claimed they had ordered the pump, etc...and were waiting on their arrival. I told them to contact me when this was completed (it is at a GM dealership). with proof that the parts were either OEM or a respected brand. I know nothing about these options.

What are your thoughts?

Found this article.

There is a Toyota TSB to replace the pumps, valves and add a new intake duct for the pumps. I'm sure you're way out, but there might be a warranty extension. Try calling a Toyota dealer and see if they can look in to it.

It doesn’t interfere with the operation of the truck. They run about 1 minute on cold start. They are for emissions, and are known to wear out, especially if you take them swimming.

Let the dealer fix it as this can get quite expensive, There are bypass kits reasonably priced though.

You can also disconnect the system, two gray connectors on the front left of the engine. You'll get a cel but system won't operate. Had mine disconnected from new since owning my 2010 until I sold it.

Don't know about Minnesota, But in Texas.....Texas law prohibits any person from selling, offering for sale, leasing, or offering to lease any vehicle not equipped with all emission control systems or devices in good operable condition.

I know a used car dealer that got a hefty fine for attempting to sell a vehicle with emissions DTC's, They demanded the emissions/inspection report which led them to the Inspection Station down the road....He was selling Inspection Reports to a bunch of local dealers using his own car to skirt the OBD Emissions check. After a thorough audit....They yanked his Inspector License & Fined him well into 6 figures.....He fled back to his home country (Lebanon).
Then they went after all the dealers, Half of them got fined into oblivion & no longer exist.

Had same truck, same year. Paid $2200 to replace this emissions based component. Get the proof work has been completed by a dealer. No other major issues with these trucks--forums will outline ownership gremlins after this to be more minor.

I spoke with my mechanic today. It sounds like it heats up the cats faster ??
He has replaced the valves, but has never had to do a pump -- does that sound right?
Edit: I had asked him what he would charge a customer -- I believe it was around 1400.00 for the valves. As stated below, he has never had to replace a pump, apparently.

Dealer called me today, left a vague me message about the parts coming in. Waiting to get more info, to share.

Yes, exactly. I, from the get-go, was going to walk away if this wasn't fixed correctly.
MN doesn't have emission testing, but if I was to ever move out-of-state, it might become an issue.

Yes all this does is push fresh air into the exhaust manifolds feeding into the cats. It consists of 2 pumps and 2 valves. It runs at cold fast idle, and shuts down after about a minute, or if you touch the gas. Combined with the rich mixture, it accelerates heating the cats.
