Jerry…the lifetime warranty on the engine and drivetrain covers all lubricated internal parts. This warranty comes standard with the typical warranty that comes with a new purchase. It is not a warranty I had to buy or that they are giving me because of my troubles. I do not believe that all dealerships participate in this offer to their customers. I do know that if I ever have a problem that the warranty is recognized by all Toyota dealerships.

As far as the light…since my light came on more than once, my situation may be different from yours. My dealership says they have personally only dealt with two vehicles total having this problem…mine and one other. The dealership told me that the other owner was ready to forget about it and was satisfied that all was well since the light hadn’t come on in a while. The service department felt this was a poor decision on the owner’s part. The light can reset itself after several ignitions and the problem may only have “appeared” to have disappeared. Again, I was told that the fix would mainly affect emissions. However, as we discussed the movements and actions behind a properly operating camshaft, it seems that both acceleration and gas mileage are affected as well…when the cam is retarded, the opening of the valves, the spray of the fuel, and the combustion of the air and fuel mix are not harmoniously occurring at 100%. I believe that I read that an over-retarded camshaft can be good for more torque when purposely geared and timed for that…however I think it is bad for mpg and quicker acceleration.

Anyways, I think I’m going to put my trust in them to do the right thing. I hope that some experts out there can either validate this decision or present evidence otherwise.

In addition, I wish Toyota could get itself off the news for all of these bad things. All of these allegations that they knew about sticky accelerator pedals and injurues and deaths associated with them, makes me feel like I’m truly witnessing a turning point of a once-great car manufacturer. Let’s see some improvements! Some real bad luck…

Sam,
You said you have a lifetime warrenty on the engine and powertrain. Can you expand on that? How did you get it. Did they give it to you in writing etc.
So are you saying that your dealership said if you had the check engine light come on and had the P0022 that you the truck needs this repair even though the check engine light is no longer an issue. Is this because you had to bring it in a couple of times, or is the repair necessary regardless? My point being, my light came on once and they changed the oil later that day and the truck has been fine since, but this sounds like I may still have an issue. ??? Anyone else hearing the same thing as Sam?

The tsb for code p0022 is now to replace the intake camshaft. This is the plan for my truck. They say that although the check engine light has been off for sometime now, that several restarts of the engine will cancel the code itself. I thought everything was okay since the light has been off. The dealership says that the greatest difference will come in emissions. They say I need to have this repair to ensure that I won’t have any state inspection issues later down the road. (Apparently others have decided not to take the fix because they perceive that all is okay now that the light is off…what do you think?) In addition, they said that since I have the lifetime engine warranty covering all internally lubricated parts, that I should rest assured that this will not compromise the integrity of my engine (and if it did, then I’m covered anyways).

I’m awaiting the dealership to notify me of the arrival of the parts. They anticipate no more than a two-day repair. I have already established I don’t want a small sedan-like loaner. The dealership seems to be complying on all requests so far.

I am also negotiating some parts (like running boards and fog lights, etc.). I’m hoping I can get a few things at wholesale prices to ameliorate my strife. I already have the free oil change, the lifetime powertrain warranty, and lifetime engine warranty covering all internally lubricated parts…so I guess I’ll also ask for the car wash too…anything else?

Last thing…now I’m waiting to see if my accelerator is affected by this new recall.

Next thing up….the A.R.E. Z-series truck cap with Yakima rack will be installed in a few days…

Oh…one more thing…for those of you that have the full cloth front seat with fold down center console (not the two buckets with center console), do you feel that the left thigh bolster is less built up and less supportive than the right side?

CSM – Well said. Good luck.

Richard – That’s what other dealers have been doing to fix the issue on other trucks. The idea is that the contaminant is getting into the cam position sensors and clogging them up so they aren’t working correctly. As a result of malfunctioning sensors, the ECM (computer) shuts off the variable valve timing (intake) system, or VVTi, because it can’t accurately measure where the cams are. The computer then sets a check-engine light because it knows that one or more of the cam position sensors aren’t working correctly.

They pulled the pan to remove VVTI on Bank 1 to clean off reistall valve and test VVTI. I have no ideas what this means. Perhaps Jason will comment. If I understood the service writer correctly, they now have a TSB out.

Good luck to those still having problems.

I like to look at problems from an outside point of view.

Toyota has a specific problem with some of their new trucks. In reguards to the P0012/P0022 error code, this problem is either a false error, or a real error. I would like to think the new 4.6 Engine was well designed. (As it was mainly constructed from the design of the 5.7) I really like my truck, and would like to see the problem fixed. I have the type of luck that if I did get a new truck, I would have the same problem. Like I said earlier, I will be on-board so long Toyota takes the problem seriously. By saying that, I am not alloting Toyota an unlimited number of tries to fix the problem. At some point, you have to cut your losses and run. Take Care All.

Mickey – Agreed. Hard to believe a staunch advocate of domestic trucks can argue superior quality when they also talk about the whole “Monday” truck scenario. Which is it – are the workers conscientious and committed to quality, or are they spiteful people who do the bare minimum? Clearly the answer is both, but it’s hard to get excited about a UAW vehicle when the reality is that “Monday” trucks exist.

Richard – Thanks!

Good info. I have had similar problem. Dealership changed the oil on Saturday. Light stayed on. They said they will have to pull the pan, but need to get permission from Toyota on Monday.

Will keep you advised.

Again, thanks for all the good info. I feel better and hope to have my Tundra back and running without the check engine light on – soon.

Jason if anything anonymous just killed the union. Is this the way union members are suppose to work there anonymous? On Mondays union workers work partially instead putting what they are getting paid for? Just because it’s Monday they don’t have to care what type of job they do? You crack me up anonymous. Yes Jason notice he has a “Cybil” personality. He uses his 3 personalities he has Me, Myself and I. That constitues the “WE”. It goes to show there anonymous not all people are like you (Thank God). CSM is staying upbeat about what has happen to him. Like I said before anonymous you have no clue about the word “Empathy”. You know the rule there anonymous don’t let the door hit you in the rear.
