ok so its throwing a P2135 code now and keeping the car in "ENG PWR REDUCED" mode and i am honestly lost on what to try next.

 

I have this same problem my friend.... sucks *****! I have no idea how to git rid of it either.

 

try this. i disconnected both sensors (pedal and throttle body) and took off the negative battery cable and left it off for a few minutes. plugged the sensors back in and then connected the battery cable again and its been fine since then (this afternoon)

 

What pedal sensor are u talking about? I've tried unplugging the throttle body and the pcm and the battery but so far no luck. Am I missing a sensor cuz that would be awesome..

 

its the one thats connected to the throttle.
it looks like there is 2 but you only have to unplug one of them

 

so your talking about under the dash? like actually connected to the pedal itself? hmm i might have to check this out. i really dont want to take it to the stealership or buy a new throttlebody....

 

yes its (somewhat) connected to the pedal.
the throttle body should be fine but i havent had a chance to drive it more than once since i did this

 

That code should be for the gas pedal itself, not the TB under the hood. They are both technically "throttle position sensors", one reads desired input and the other is just a check for throttle blade position. It's a double system on these cars, there are actually two on either spot, TPS 1 and TPS 2 in datalogging sense, just as a failsafe in case one of them quit so you don't lose throttle control or get Toyota'd.

 

Well that makes sense I guess. So how do I get the sensors to correlate again? How can I reset them?

 

it is the throttle body replace it and the code goes away

 

you shouldn't have to replace it. mine went away after i disconnected the battery. if it comes back after that then you might have to

 

had the same problem for 6 months every few weeks it comes back

 

the sensor came out when i was racing so i thought i blow the motor, it went into limp mode (eng pwr reduced)

just make sure the sensor is plugged in to the throttle body good.

 

just checked the plug its on their good the car does it every so often like every 2 weeks

 

thats booboo then, i wonder why it does that now

 

correct I had the same problem also throwing p2135 and it just gradilly got worse to where it wouldnt move and would shut off. I had access to hpt so I just got an ls4 tb as it was the same price. I am known to have weird stuff break on me.

I trouble shooted first and borrowed the throttle body from my brothers colorado. It started up without a problem so I knew right away what it was.

 

came back again last night, paired with a flat tire made for a great night.
i'm thinking about just replacing the TB but all i can find right now are TB's for the 2.4 which i doubt would work
