Wait til those huggers find out that they have to buy a new battery... and what's left of the old one is about as toxic and it gets!

And this is why i will only buy GM products I have never had a problem with them. I wish that Toyota would own up to it if they did make a mistake at least that would show me they are human and care about the customer's that they put in danger. I have drove and rode in Toyota's line nice lineup but not for me. To me they felt cheap. And now i am really glad i bought GM. Ok off my soap box.

With all the driving that I do, I always see a Prius in the fast lane doing 80 plus mph. I really wonder how efficient they are at 80. The electric motor and gas engine have to both be running their little guts outs.

With Toyota be the darling of the media for the past few years it is refreshing to see them turn on them like everyone else.

Boy I sure do miss my good ol throttle "CABLE", man those were the days. All this to save a cable and a return spring.

plus the extra parts not needed for cruise or traction control (cost, weight, packaging), plus better control over 'torque management' for reduced warranty issues.


although this is making me rethink my want of DBW in my 67.

Isn't that the truth?:lol:

No one ever talks about the battery disposal,what a nightmare that'll be.

Hey guys, I have been following this very close and also got my hands on both the denso and a CTS pedal. I can confirm what was posted in that first link, however there is a twist.

The CTS pedal I took from a 2008 Camry had a WHITE plastic on the tip of the two teeth that fit into the groove.

Also - the Toyota uses MAGNETS in both pedals to send the signal to the PCM for throttle input.

The CTS uses a pair of banna shaped magnets fixed to the top of the lever. The sensor sits inbetween them. As you press the throttle the magnetic field increases. The Denso pedal does the same thing, but has the magnets fixed in the pivot of the center of the pedal.

Some folks have experimented with putting EMI signals through the cars and were able to raise the RPM as if they were pushing the pedal.

As far as I know, Toyota is the only one using the magnets. GM at least uses a contact sensor (just like the TPS, etc).

Now, for giggles and grins I put the CTS pedal in hot water for an extended amount of time trying to encourage swelling and moisture collection on the drag assembly. Guess what? No drag - no snag, no sticking.

My money is on there being a known problem where the sensor picks up EMI and translates that into throttle request causing the vehicle to race.

Finally - I can say for a fact that if you pump the brake on the 2.4 four banger Camry while holding the throttle down, then try to hold it down...all the vacuum is depleted and the vehicle will overpower the brakes. I'm talking standing on the pedal as hard as you can to the point of bending the seat and it will at first slow, then little by little overpower them and begin to accelerate.

IF you simply hammer the brake ONE TIME and hold it while going wide open, the car will stop. Problem is, in a panic most drivers would end up pumping the pedal and losing all the vacuum assist prior to crashing.
