Sticking throttle

[Defyant]

Anyone else had this happen?

Scary as hell, all happened really fast too.

Left my brothers driveway flored it for a quik 50m blat went to brake for the corner and the throttle stayed flat chat, brakes went into abs mode managed to take the corner with a lotta unwanted noise and everything was good again...... I'm sure it wasn't the car mat.... I've seen a recall about this but didn't know our Aussie aurions were affected by this.

Two things:

- The recall in the States regarding the floor mat was with in relation to the all-weather rubber mats which are larger than the carpet mats and when sat on top of the standard mats, would be prone to sliding over the accelerator pedal. This can be a potential issue for anyone really, and is of no fault of the mat.

- Also in the States, the recall regarding the accelerator pedal was in relation to a locally sourced (CTS) accelerator pedal that operates quite differently to the Denso accelerator pedal found in the Australian Aurion. This issue in no way affects us.

But that said, thirdly:

- In questioning the possibility of an electronic failure or default in the ECU responsible for accelerator/throttle control, NASA were involved in looking at that and found there was nothing at fault there. Read the following for more details:

Toyota's Throttle-by-Wire System Cleared by NHTSA

Also, there has been discussion about "tin whiskers" that was brought up after all this discussion on the accelerator pedal which may have made some people think the accelerator pedal was really at fault. You can read more on that research here:

http://nepp.nasa.gov...-app-sensor.pdf

The accelerator pedal being referenced to in that paper however is a 2003 Camry Accelerator pedal which uses a potentiometer as the form of throttle control. The accelerator pedal used on the newer Camry (both CTS and Denso) utilise hall effect sensors to measure the throttle input and therefore are not affected like shown in the paper.

What you experienced would probably be something completely different to the cases experienced by those in the States. Just saying this so others don't get in a panic that "our Aussie aurions were affected by this". In saying that, it could be something as simple as some other obstruction around the pedal area to something as serious as a throttle body servo issue. If you are absolutely sure it wasn't caused by your own wrong-doing (eg. I've once hit both the accelerator and brake with my shoe before), then this is something that you should be inspecting with more detail.

Take it to Toyota and get them to do a full inspection including running scan tools, etc. I wouldn't speculate until you know for sure what caused it.

Cheers guys , shes due for an service in the next few weeks, i'll deff be getting toyota to check this right over.

[trentmeyer23]

If you are really concerned, it would be a good idea to have it checked immediately.

get it to toyota immediately, they'll be able to tell in the logs what the pedal request position, throttle plate angle and if the brake was on at the same time where it should have gone to failsafe.
