Do you have a touchy gas pedal?

If yes, then the following may help. My 2010 tundra was very sensitive. I couldn’t really control launching from the line. Recently I nuked my mass air flow sensor. Suffice it to say sometimes I’m a dunce. Anyway I bought a Toyota replacement part and installed it. Once the computer and it learned each other the truck smoothed out. Lo and behold, the sensitive pedal vanished. Now it feels like it should and the line launches are gone.
Just thought my experience might help others.

 

My 2013 did. 2021, not so much.

 

Same here, changed mine out right away after buying it. It was way too touchy to make it drivable in traffic.

 

Changed out your MAF right after purchase, or updated gas pedal like many have done?

When you say you "nuked" your MAF, did you cause its demise?

Were there driveability issues before? (other than throttle response)

If you physically damaged the MAF, then unplugged the battery to install a replacement, I wonder if the ECU reset/restarting the learning process has eased your touchy Go pedal without replacing the pedal like so many have done.

Definitely keep us posted on any developments or if the truck reverts back to its previous state.

 

Changed the pedal with the 04000-0440C

 

If applicable you can remove the small shim for free.
I did that in my 08 and saved 40 bucks.

 

My gas pedal is extremely touchy on my 2012 Tundra. I'm actually surprised that the TRD Supercharger ECM flash didn't correct the issue.

 

I saw a thread about that after I put the new one in. I also saw the service record where they put that spacer in, don't know why they did that.

 

I feel pretty happy with how my 2012 functions. If ya stab the pedal from a stop, she will leap into action for sure. But I usually drive the truck like a truck, and really ease into the accelerator for smooth, drama-free operation.

Maybe I am compensating for this hyperactive pedal situation, but the truck seems easily capable of both smooth or somewhat violent acceleration.

 

I nuked the MAF sensor by spraying starting fluid in the air box. I did that because one of my sons put diesel fuel in my gas can without marking it. I put that fuel in my truck. Truck died after a minute of idling. Thinking the fuel I poured into my tank must have been old, I squirted starting fluid to help it get going. Dunce move.

After having installed the new one and experiencing the change in performance, it makes sense how the MAF could cause a drive by wire system to act poorly.

 

Ah yes. I remember reading of the incident.

How many miles on the original MAF?

 

I kinda like the touchy pedal. You can scare passengers with it lol

 

220,000 miles. Incidentally, I had a coil pack go out about 225,000 miles which seems about right for Denso coil longevity.

 

I have the touchy pedal issue too...
I scare the crap out of people at the light when I suddenly start doing mini burn outs but still move at normal speed.
I thought it had to do with the recalled pedal so I took it in and they refused to replace the pedal because I have aftermarket pedal pads. LMAO

Just in case though, I cleaned my throttle body completely and I'm waiting for my MAS cleaner to come in

 

YES - i added a Bully Dog Gt (used - so affordable) and also changed a few other things - mainly wanted the display of my trans and engine temps...so was an all in one solution...

it tamed the jumpy start with the pedal...but it left the "tow haul" really sensitive (like it when towing and needing a launch at a start sometimes)

 

Can you change the Gas Pedal feel or setting via TechStream?

 

Meh…I like the touchy throttle

 

I can't say with certainty, but, I have explored almost every "customizable" function of Tech Stream and don't recall any setting having to do with the gas pedal - FWIW

 

Same on my ‘10. Fixed the touchy gas pedal in about 5 minutes for $0.

 

No, but there is tuning software that can. Not an inexpensive route though.

 

I wonder if there is a shim on my 2012.

 

Two nuts and a plug. Takes 10 minutes on/off to find out.

 

My 2012 CM Platinum I had a few years back had a SUPER sensitive gas pedal. If I came to a stop sign for a quick stop and went to add a little gas to get moving again I would end up bobbing back in forth in the driver seat. The thing wanted to launch!! It was kinda cool at times.. I never used tow haul in that truck that I remember.
Now after selling my recent Tacoma, I’m back in the 5.7. I got a 2016 dclb trd or. If drives fine but it’s not sensitive and launch hungry like my 2012 was.. so now I just drive around with tow/haul mode on all the time.
Is there anyway to bring back that touchy launch gas pedal back? What are people doing with this shim? Maybe I can do the opposite.

 

Look up throttle controllers like Pedal Commander or Bully Dog. You definitely don't want the Tundra with the bad pedal; it's not a sensitive throttle, it just makes the vehicle lurch with bumps.

 

I thought the touchy throttle was a feature.
I hear the 2.5+ guys saying they have to put it in Tow Mode to achieve the same acceleration program as the 2nd gens or use a programmer or something.

after the lift and 37’s I think it’s perfect.

I’m sure I could trash the gears in the rear if I stomped it all the time but I don’t. I never do. Eventually I may need new gear ratio but that’s a different story.

TLDR - I personally don’t see an issue with throttle response.

 

that’s because you have the 2nd gen with the launch pedal and after putting 37s on it, it brought back down to normal.

 

Is there a write up for this somewhere? I searched and did not see anything. Where is the shim? Thanks.

 

I can't remember exactly, but remove the gas pedal assembly from the floor (maybe 3 10mm bolts?), unplug it, and flip it over. The pedal is a lever that presses a button, and the washer shim is between the pedal arm and the button. I seem to remember it being very obvious when I looked at it. Sorry I can't be of more help.

 

Might be old news, here is a vidja I found covering these shims… I too have the touchy pedal on my ‘07, and would like to calm it down(teaching my daughter to drive on it has gotten to her confidence a bit, with the unintentional burn-outs!
It appears the shim is simply a way to cause more resistance(physical, not electrical) in the pedal, to make it harder to push, thus “easing” the jumpiness. I’m not sure how removing said shim would fix the touchiness…..‍♂️
2:07 mark is when the shim action starts. No real explaination of how/why until then.

Removing the shim on my 2007 SR5 did NOT improve the sensitivity of my gas pedal. Replacing the pedal with a later version - upgraded pedal, did (04000-0440C). The change wasn't "dramatic", but, enough to improve drivability.
