No response at gas pedal

Yallrun · #1 (**permalink**) 07-31-2005, 07:00 PM

I was just coming home from the store, stopped at a stop sign in the mashed the gas to go, but just idol'd threw the intersection. Mashed the gas almost to the floor still nothing, kept mashing it them boom truck took off. WTF? Did this all the way home and check engine light came on! Anyone have any idea what's going on?

Thanks,
John

Partially clogged exhaust?

Throttle position sensor would be my guess...Some people have reported similar symptoms in the past and it turned out to be the TPS.

That's it. Had the same problem a year ago. Changed the TPS and all is good again. There is a thread around under something that I forget now. I think I payed around $275. for the part.

I was thinking the same thing. Now if I knew where that stupid thing was and if is difficult to change.

Thanks guys, I'll toss a new TPS on it. I reset computer and it's fine now, but I'm sure it will return.

Thanks again,
John

I've noticed that my 2005 doesn't respond quickly under WOT... However, if I move the pedal 50-75% of the way, it screams... It's part of the electronic throttle (as opposed to the mechanical throttle cable, that it replaced) and the computer's attempt to improve mpg, and even out driving.

On the Tundra's there are 2 posibilities but more than likely it is the Throttle Pedal Sensor not the the Throttle Position Sensor that has gone bad. I had the exact same symptoms when mine went out. I installed it myself in about 15 minutes. On the 2000 it is located on the passenger side of the throttle body. It might be under the accelerator pedal on a 2001 but I am not sure I know they moved it there on later models. Also your sensor will go out again and mine ran fine for a couple of weeks before it went out again. I would take it and get the code ran to be certain and then fix it because it might not start working again next time

Good Luck.

It's actually called the Throttle Lever Assembly(TLA)if you will.

This is the Toyota part number 22060-50011 at least for the 00. There's a couple of pics here if it helps. 3 bolts, 10 min like Mitchr, said.

Tha is the part only 3 screws and a electrical connector. Remove the old(bad) one and line up the flat part that protrudes from the TLA and then you will need to turn it toward the front of the truck about 20 degree's to allow the screw holes to line up. This is if you have the one located on the throttle body, I am willing to bet that the throttle pedal sensor is on the later models and is actually located somewhere real close to the accelerator pedal.

I'm curious, what ended up being the problem with yours afterall?

The sensor had failed for whatever reason. The way I understand it it is basically a rheostat that controls the input the actuall throttle sensor (drive by wire). Did you have to replace yours? I noticed the photo's.

No I didn't, because when the my mechanic checked it with the OBDII, it came up with a different part, but related. He then subsequently called Toyota for their advice and they suggested changing more that just that sensor. I don't know why. I ask him, well what if that doesn't fix it? He said, that if that didn't fix it, then he wasn't doing his job right and he would remedy it. Which I thought was very fair. They only work on Toyota's. All x-stealership mechanics. It only cost $50 buh anyway. One year and 6 mos. later, still hasn't missed a beat.

I changed the fuel filter and the problem seems to be resolved for the time being.
