I have a gurgling which I am pretty sure is air in the heater core, Gonna ask my guy about it in a few days.

No idea on your other problem. Not under warranty anymore?

 

No the Warranty was 3/36,000. The truck is just over 3 years and at 46,000. I just don't understand how these parts that do not have much impact on performance (other than putting the vehicle into limp mode) can cost so much.

The mechanic said he has never seen this in a Tacoma, but is common in Tundras. He said it can be caused by dirt entering the system. I don't even take the truck off road and the air filter is changed at recommended interims. Just doesn't make sense to me.

 

John, you might want to look at your warranty book. I'ma thinkin that these parts are included under the federal emissions warranty which runs much longer.

EDIT: took a peek at my warranty booklet. Looks like that by MY 2014 they have now been able to weasel-out of the longer warranty commitment for a number of the emissions components.

I took apart one of those pumps once. It consists of a dinky 12v motor with a cheesy foam air filter. I don't get how there would be a double-whammy kind of thing where the switching valve would also fail.

It would be a very cold day before I coughed up $2k for these. Run from that dealer. If worse came to worst I would hunt for used parts.

 

Check this web site for used parts: http://www.car-part.com/

 

The federal warranty only covers 2 years 24,000 miles (this part doesn't fit in the 80,000 mile one). The mechanic said the vehicle would run more efficient with out the damn part. I would ignore it if I could, but the truck goes into "limp mode" and barely goes over 40 mph. I researched that the Tundra's I think 07-11 had a recall on these parts. I also talked with two other mechanics in town, they said it would cost around the same and that they aren't allowed to install a by-pass for it (I would look into it but I would have no idea what I was doing).


I'm going to try and fight this garbage to the top though, Toyota should cover the cost of these malfunctioning pieces that are mandated by federal law. The truck is only 3 years old and I am already having to cough up $2,000 repair bill.


I'll look at that website also, thanks Gatorstaco

 

If you've bought a lot of Toyotas in the past, calling their 800 number will likely result in a goodwill fix where they'll split the cost with you (usually 50/50).

 

OP please keep us posted on what happens with this.

This falls into the "nightmare" category since those parts only operate for a very brief time when warming up. I hope Toy sees the folly of this and does something for you.

 

Had the check engine light come on today and took it into the dealership. They determined it to be a failed air injection pump and switching control valve and quoted me $1,950 for parts and labor.

Just a dumb question: do you trust their diagnosis? While the parts / labor may be comparable at other places, do they agree that the check engine light code matches what the first guy diagnosed?

 

1. ^^RTFM has a good point. What was the code (codes) that appeared)?

2. I took a quick look at car-part.com and if this is the air pump located on the passenger side toward the front they are listing several '12-'14 in the $100-400 range. You would have to confirm application of course. And for replacing that part it is about as easy as things go.

Did not look for the switching valve but I suspect it could also be found for much less with just a little effort.

 

And, someone could overnight those parts, and he'd still be way ahead.

 

I get that gurgling sound occasionally, usually at low speeds (20-30 mph), and very light throttle. Is that where you hear it? I'm at almost 24k miles, and mine has done it since new.

If you're thinking of buying a new pump, I just did a quick look-see, and priced that pump at $939.04 on a dealer site I use (Titus-Will Toyota-Scion in Tacoma, WA). Also PM Roman on here (Toyota of Cool Springs) for a price. I don't know if the "switch valve" is a separate part (maybe they meant the diverter valve, $464.41), but if so, get him to price that as well. Even paying a grand or more for the parts and installing them yourself (I can't see how installing the pump takes more than ten minutes) is a lot better than $1950.

 

Thanks guys. I'm still waiting for a call back on the specific part numbers and diagnostic codes.


Sharkinstx: The price that you found for new parts is around what he quoted for the parts. Said around 3 hours of labor.


I'm also going to call Toyota Care this afternoon and see if I can get any restitution from them.


I'll keep you guys updated on how that goes. If all else fails I'll get the parts used and try to install myself if its not too hard. Also, starting to look at by-pass kits. http://hewitt-tech.com/store/index.php?l=product_detail&p=14

 

Got an Err on my 05 Tacoma code of p0418 which meant bad Air Injection Pump. Started looking around and realized how expensive they are. Even a used one goes for $100 if your lucky to find one. Well after 3 weeks looking on the internet found a mfg that rebuilds them $150 plus shipping, with core exchanged. A1 Cardone is the company that supplies the rebuilt air injection pump, part # A1332504M is the Tacoma part, this is a crossfererance part number MFG #33-2504M , hope this information helps someone. http://www.carid.com/cardone/remanufactured-secondary-air-injection-pump-mpn-33-2504m.html

 

Or post how to get rid of this BS pump, wiring a fuas pas to render this item invisible to the ecm.

 

https://www.hewitt-tech.com/store/ offers a by pass kit but your air injection pump needs to be in working order. It can be replaced with a resistor, but you need the block off plates, so the exhaust doesn't back feed and start an engine fire. Hewitt offers a resistor along with your motor connector and $80, so he can attach it.

 

I have a dumb question about this pump and filter failure. Mine went at about 47K miles on my 4 year old Tacoma. I had just added oil to the engine, and was wondering, could overfilling the oil have caused the filter/pump to fail? The car is at the Toyota dealer and will cost about $900.00 to fix. I do not want to blow a second unit.
Thanks

My 2012 Tacoma with 64,500 miles on it had air injections pump and valve assembly failure - dealer technician said they have "re-designed" the part, but Toyota has not recalled the Tacoma (They did recall other models like the Sequoia and Tundra for similiar issues). Bought the truck new, and have had dealer do every bit of suggested and required maintenance - still cost almost $2,000 to get truck repaired. Why is Tacoma not included in the recalls!!!

 

Recalls are for safety issues and may be voluntary or involuntary. The air pump and switching valve is an emissions thing.

 

$2000 Repair Bill at 64000 miles :-(

I appreciate your input! Ok, so the term "recall" is not accurate -
My question, then, is if Toyota honored the repairs using redesigned parts on other models, as is well documented with a short internet search, then I'm very frustrated that they are not doing the same for our Tacoma.
$2,000 is a very hefty repair bill on a 5 year old vehicle that has had all required and recommended maintenance performed at the dealership where we bought the truck. $2000. is a lot of money in my household, and not what I expected from a well maintained, purchased brand new Toyota.
Very disappointed.

 

^^ Did not intend to sound like the word police but in the world of automobiles words mean everything, and in your case the difference between what could have been free to you but is instead going to cost a ton of money.

Are you mechanically inclined at all? Like I said in an earlier post above I would be hard pressed to pay that kind of money for those parts. I've had them apart and they are rather simple. So if this were mine, I would first take a serious look at finding things from a wreck and doing it myself. Car-part.com is one of the sites I have had good results from but there are also others. You may have to chase it some.

A lot of us feel the type of anger you have. But you have to assess the core of why things like this happen. All this emissions stuff is the result of government. Car manufacturers simply respond to what is mandated of them. And it is going to get worse as more government regulations pile on, much of it being totally mindless, create more expensive fixes that need to be made because of the law of diminishing returns. There are lots of places where perfectly good and running transportation is sidelined forever and cannot be sold because the owners could not afford to have something rather insignificant fixed.

 

Was the failure caused by the cheap foam filter falling apart?

 

Where is the "cheap foam filter"? Is it that the filter disintegrates and gets drawn into the pump vanes? Or, how would the filter cause the pump to fail?

Air pumps are kind of a stone age emissions part nowadays. I have a friend who's a longtime master mechanic, and works as a fleet maintenance manager for the city of Dallas. He couldn't believe when I told him that the Tacoma has an air pump - American manufacturers quit using air injection years ago.

 

The image in the TW post looks like the older style pump - I don't know if the newer one like mine uses a similar filter setup.

 

Unfortunately its still there, foam and all. My '14 has it.

 

I have an 05 taco 2.7L 4x4 with the same P0418 code. My pump runs fine, my air switching valve operates fine hooked directly to a battery.
I am not getting 12v from the ECM upon a cold start while the pump runs? My questions are:
a) Is there a relay for this valve? If so Where is it?
b) Could the ECM directly control this 12v valve?
c) My Pump runs, there is a small tube going to the Air Switch on the intake. It is not a vacuum line. I checked the switch and it has high impedance with every combination of contacts under vacuum or with air pressure. ( I assume it operates on the venturi causing vacuum theory) So what does this switch do? does it detect Pressure/vacuum and then open the Valve? I know the bypass kits available plug into this connector among others so it definitely plays a part. I just need some specifics that I can test to get my answers. Thanks for looking, sorry for the lengthy post.

See BBBind.com for schematic.
Air injection control driver powers the Air Switching Valve.
Upon cold start both air pump and ASV should have bat voltage for a min or so.

The control driver is in engine bay on the passengers side above ABS( on my 07, 2.7, 2 wheel drive.)
The ECM, according to its program,controls the air injector control driver module.

Regarding air pressure switch line to air pump, can't say what that's about but pump and ASV are electrically controlled.
