Help!!! Car won't go when you step on the gas!!!

Hello all...01 s 430. Normal driving today. Came off the freeway and when I went to accellerate nothing happened. I put it to the floor and it accelerated very very slowly. I can only imagine what would have happened if I was trying to cross a busy intersection with my kids...wholly cow that was scarey!!!! I pullled over and turned car off and restarted it and it worked fine for a few miles then did it again...but this time with the check engine light....uuuuuuuggggg...any ideas what's going on????

I believe you have a transmission problem.

Believing and knowing are two different things. That said, I'll bet a dollar to your donut what your problem is. And it's not your transmission. Relatively simple, actually. Not super cheap, but simple.

Your gas pedal has a sensor behind it; it sends pedal angle information to the throttle. When the senor goes bad, the pedal doesn't work.

The pedal replacement is a DIY job, about 10 minutes with basic tools. The pedal itself, with sensor (its a scissors-looking assembly) is available at StarPower for $150 (better than the dealer's $300):

Good luck- BTW, your code should be P0402 for throttle / pedal sensor...

p.s. If you just want to take it to an independent, the part and labor will run you about $250 average.

Are these pedals/sensors adjustable? Seems like my R129 doesn't want to move until the pedal is about a third of the way down. Thank you.

Not to my knowledge- I was told by my indy that a slow to respond pedal is the first sign- mine seemed sluggish (I actually thought I had an engine tune problem!) until kickdown, until it just died. Felt like a whole new car with a new pedal assembly!

Thanks guys...I'm going to get a code readed today to double check but I have a feeling from what I've been reading that you're correct!

Something that happened to me, may not be the same but similar:

I was driving, and accelerating a good bit, and I guess I caught one of the revs a bit too soon, and it's like the transmission went out of gear. It wouldn't accelerate anymore, I had to stop the car, put it in park, and back in drive.

I did a transmission fluid flush/filter change, and new transmission mounts, and I never had that problem again.

Although in your case it appears that it's a throttle issue with the pedal, since I think code p0120 means that. I never got any codes.

Yes, P0120 is a pedal sensor. You need the entire scissors-pedal assembly.

Maybe you could take the parts out of a new Toyota and rebuild the pedal? Sorry couldn't resist.

Buying off negative feedback is shameful. Offer the refund without conditioning it on removal of negative comments. And for god sakes post in the right thread!

Base on my experience, it's your transmission may seem to be the problem...

Your experience would be incorrect, its an electronic pedal issue.

No revving. P0120 is the code, and it DEFINITELY not a transmission issue. The part is readily available both new and used.

I have a E430, but my pedal does not have a sensor. Do I have something else?

E430
Also an E430

I also have an E430 that did the same thing yesterday. I was barely able to get home. And toward the end there was a whirring noise coming out of the engine area and the engine light was on.

Press on the accelerator and the engine revs up but won't go anywhere - won't engage. After turning it off and waiting a few minutes (maybe to cool) it starts up again, and will go for a few miles then quit again.

Have to go to the shop with it this week, but any input is appreciated.

I have a E430 with the same problem. Nothing happens when you step on the gas. I replaced the accelerator position sensor, but it did not fix my problem. Could the part I received from Autohaus be bad? Or do I have another issue? What next?
