The pumps are 12 volt DC so you can also test the pumps by making yourself two jumper wires to run from your battery. Disconnect the cable connection to the pump and make note of size terminals. Get yourself the correct terminal connectors to attach to the pump terminals so that they don't touch each other. Take the other end of your jumper cable and touch one to your battery + post and then shortly test to - post of your battery. Just for a second or two to do a bump test. I had one pump that would spin but the other did not so I have the choice to order only 1 pump before tearing into it. Wiring from the pumps: Red is hot and black is ground.
I replaced both of mine in a 2007 tundra. Also bought the update breather neck to avoid the water being sucked into them again. Replace both and clean them if they aren't cracked, maybe have them as spares.
@surfandsnowbord I got mine from a toyota dealership, the part #17621-0S012. Type that part number into Google or a search engine and it should bring the part up. Not expensive but it is the updated version of the air pump breather inlet. There is a cap looking feature that bends over the line inlets. Another idea I had found was you can drill a hole into the rubber on the bottom of the air pumps to allow water to drain.
Good job my amigo look my toyota tundra have the some problem i need to fix it im going to just like how you did in this toyota tundra cuz my is not running goog when im driving on the free way my friend but thanks you for this video amigo im going to waiting for the next video ok bro 👍
Thanx for the great info. These used to be under the intake . . How many hours should I charge? And also, did you replace the duel check valve? Thanx again in advance!
My friend thank you for the video, I bought 2 pumps and would it matter if I accidently plugged for example bank 1 into the bank 2 harness they look the same?
Depend on how the system work, computer maybe turn on only the bank(s) that need air injet into the exhaust. If it turn on the wrong pump then computer will set the Fault codes and turn check engine light on. If after many km of driving both in the city and hi way with no engine light on, you are good
Thanks for your video. I have a 2009 4.7 and have replace one pump that’s on the right side where would I find the other pump? It’s a 2009 tundra 4.7 regular cab.
thank you for video, question: if by accidently plugged bank 2 to bank 1 or bank 1 to bank 2 will it matter? I bought both new pumps and they both look the same, the reason I ask is because i installed both and erased the check engine code but after a day of driving it came back on and truck went to limp mode.
Yes, PCM turn on each pump separately depend on which bank need air and need more air. That is why they came with 2 pumps .So, switch the pump connectors back, clear the codes and try it, good luck
Great Video!, I have a 2012 Tundra, V6 and had air injection system code P2443, I did replace the air pump with new OEM air pump and new valve for passenger side, I did double check all connections are good, but I still see the engine light, I reset it but still come out, I noticed the pump not making sound when I have the switch on, any ideas why this happening , is there a fuse or relay need to be checked ? thank you
Sorry for late reply, there is no fuse or relay for this 2 pump, it control by modules for each air pump, both module are small(8 wire plug) both module at left rear of engine compt according to the wiring diagram
I replaced both air pumps. Checked first to make sure they were good. I get a p2445 code saying they are stuck off . Is there a fuse, link or relay that needs to be replaced, if so where is it?
My toyota cranks but don't start, my friend connects something to the computer and air pump and the air injection come out, you think that's the problem? Why don't start.
The inlet tube is the reason why the water got into the pumps. It was a poor design by Toyota. I just changed everything and it costed me an arm and a leg.
Why not follow the air tubing and see if it goes to the side of the engine where cylinder one is where it's at the side of the engine where bank bank 2 is where cylinder 2 is just follow the air tubing an that should tell u what bank is which
What a great, hard working, honest, and great mechanic this man is!
Your a life saver with your explaining the wire location
Excellent video! Thanks very much for posting this!
I was searching and searching for a way to to determine which pump is which. Thank you! I owe you a beer friend!
I'm glad my video can help, thanks
The check engine light came back on, this morning. I’ll have to check what happened.
Good info. Thanks for taking the time to edit and post the video. 👍😁

Thank you! I wanted to try this.
Did you get a p2445 code?
Also, if so, what part did you order?
Thank you for this video it will help me I gotta change mine now
You are welcome, good luck. Thanks for Subs to my channel

How'd you find the updated breather neck? I can't find anything specifying an updated/fixed part. Thank you!
@@surfandsnowbord I found my at a toyota dealership near me. Part number 17621-0S012

Is there anything that can be done to prevent water from getting into the inlet tubes? Like after-market tubes?

This is very helpful. Thanks you so much
Thanks for your video. I have a 2009 4.7 and have replace one pump that’s on the right side where would I find the other pump? It’s a 2009 tundra 4.7 regular cab.
It's should be at the same location unless it is had only one pump. I have to check the manual
@@silverstonespov5291 I only saw one but would like to verify. Thank you in advance.
It’s has 2 pump, the right front of engine it bank 2, bank 1 air pump it at top of engine. That is base on the wiring diagram
It must be under the cover because not visible to me. Thank you very much!

Found out that if you open them up, you can actually clean them and they will work again.
Yes, sometime it just need to be clean và especially for our own vehicle.
If both are not working will this cause your vehicle to have reduced acceleration and bad gas mileage?
@@TobyWoods-fv3ey Yes, the vehicle may going to lim mode, driving not over 80km/h
Thank you Sir
I replaced both air pumps. Checked first to make sure they were good. I get a p2445 code saying they are stuck off . Is there a fuse, link or relay that needs to be replaced, if so where is it?
I have to check the wiring diagram again to see. I didn't have to replaced any fuse or relay on that Truck
Excellent!!!!!
Why do some 5.7L models have the pumps behind the intake manifold close to the firewall??
Depend on the model year they mount the pumps at different location
I replaced both of the pumps but it is still going into limp mode what else could it be
Check the Wirings, Fuses that can cause the Pumps not working. Did it still have the same codes?
Are they both pump are the same bank 1 & bank 2 ?
Yes,Pump are the same but air hoses and wiring different
@@silverstonespov5291 thank you .. can you share then link for these pump please
@@chaldoboy1000 sorry I don’t have other link, it in the shop manual and I can’t
muchas gracias where can i get the pump
Dealership is better but you can get them from NAPA or Auto value, Canadian Tire
My toyota cranks but don't start, my friend connects something to the computer and air pump and the air injection come out, you think that's the problem? Why don't start.
Air Pumps work or not have nothing to do with the NO Start, you have other issues. scan it to see what code and go from there
@@silverstonespov5291 thank you.
Nice
The inlet tube is the reason why the water got into the pumps. It was a poor design by Toyota. I just changed everything and it costed me an arm and a leg.
All I did was check both of them the one that didn't work was bank 1
Why not follow the air tubing and see if it goes to the side of the engine where cylinder one is where it's at the side of the engine where bank bank 2 is where cylinder 2 is just follow the air tubing an that should tell u what bank is which
This fix the traccion control lights
