Unhappy Pedal Position Sensor Pot failing

Crap! Another SES light! I got this error on Monday, I cleared it, and it reappeared today; about 100 miles between instances:

Carsoft says:
168 Pedal position sensor potentiometer supply channel 1

...and I believe this is the generic equivalent:

P1624 Pedal Position Sensor Potentiometer Supply Channel 1 Electrical

My searches yielded no helpful results, other than it's not uncommon. My accelerator pedal is also crunchy, for which a TSB was created several years ago, and I'd LOVE to remedy that problem, but clearing the SES is more important. Perhaps I can do both in one shot?

Is replacing the accelerator pedal module the answer? (see the attached image, label #1, part # 35426786282)

Does anyone know if that will solve my SES error? Is there a DIY anywhere, or perhaps someone has the TSB? If anyone has done it, is it a PITA?

If the code is generated by the fault in the pedal assembly, it should clear itself after you replace the assembly. Removing the assembly is very simple. Press down on the clip you see on the side of the assembly and push the whole thing to the left

OK! Thanks for the input! Do you know if there are other conditions that would cause this error code that I could troubleshoot? The pedal assembly is a pricey part; something I was planning on replacing in the future once monies begin flowing again, but was willing to live with until then. However, if the SES light keeps coming on, I don't really want to have a "Toyota" on my hands! WOT without warning is not fun, especially in a reasonably fast car.

I can't directly answer your question, but I can say that the pedal assembly was the only part listed on the service invoice I have from the dealer for the repair of this TSB, and p/n 35426786282 is what they installed.

Thanks Cliff. I found two TSB numbers. Do either of these look familiar? 67665 or 106671 or NHTSA number 635883

I was looking for a TSB number referenced on my invoice and I found nothing. I'm afraid I can't help you there.

Well, thanks for looking! Now the big question! Did that repair solve the sticky accelerator?

I didn't have one, but I wasn't about to ignore a TSB while the car was still under warranty either. The repair was done in October 2002, about 4 months after I took delivery. I can say my accelerator isn't throwing codes...

You know, heheh, I probably hosed my own accelerator in an attempt to smooth out the stickiness. I shot a decent amount of WD-40 down the shaft.

It didn't help at all, and now the unit is throwing codes.

damn man... our pedals are electronic....

i think you damaged your pedal and the elecetronics in the assembly. you might just have to replace and call it a day... or a weekend

Well, it still works, and I've driven it this morning, and the SES light didn't come back on, but I just know it's going to. I tried removing the accelerator just to see what's in there, but I can't move it.

Tangent says it's an easy removal, but I must be pressing the wrong tab or something. Anyone removed their accelerator pedal?

Cliff-

I don't know what to say, but thanks a million.
I was just going to remove it to see if there was anything to clean, such as contacts, etc, but the FIRST thing I read from your pdfs (see attached).

Now I know I better have a new one right beside me before I attempt this!!

Did you ever replace the pedal? Did it remove the code?

Yes, and yes. Well, I had to clear the code, but it did not return.

Thanks.

I began getting this code as well as "mix deviation" codes. I think they are somehow related.

I'm ordering the pedal. hopefully it'll solve my problem.

Gently press on the release tab behind the notch (left bottom middle of pedal housing) and slide the assembly toward the brake. It appears the base is brittle; my release clip broke off, and I had to buy a new base. (Note the red circles on the diagram for locations)

Replacing the pedal did not work. Does anyone have the ETK to trouble shoot this code?
