Have Toyota Questions? Ask a Mechanic for Answers ASAP
I am Nelson, I am an automotive technician with over 12 years experience, and currently working at a Toyota dealership.
this problem does seem quite odd, I have run into a similar problem before. Is there any possibility that you could be hitting the brake pedal at the same time as the gas pedal?
Ever since the "accidental acceleration" some people had complaints of, Toyota now has prevented this from happening by causing the engine to idle and not accelerate if both the gas pedal and brake pedal are applied at the same time. maybe try to apply the brake pedal lightly while trying to accelerate to see if the same symptom occurs.
Hope this helps, and please feel free to ask for any more information if you need.
Also if you have found this helpful please leave feedback accordingly, Thank you
ok i just wanted to ensure that, that wasn't the cause, have there been any fault codes stored or check engine lights on when this does occur or when engine dies?
OK, this does seem quite odd the only thing that comes to mind in this situation is that there may be a problem with the accelerator pedal. It seems like it may not be sending a signal out to operate the throttle. But it does seem quite odd that there are no codes stored in t computer, because the "drive by wire" throttle body has many different sensors to ensure proper operation.
Unfortunately It seems like there is a problem with the Toyota website. I have been disconnected and will not reconnect for me. seems like the system may be down. But I will check back again in the morning and update you with anything that I am able to find.
After quite a bit of searching on the Toyota dealer website I was unable to find any helpful information that could help diagnose your intermittent problem.
The only suggestion that I could make is to if possible, leave the truck at the dealership for a few days so that they could try to duplicate the problem. Because unfortunately with an intermittent problem like this any diagnostic process needs to be made while the problem is occurring.
Also I know that not too many technicians are aware but one of the vehicles computers stores a detailed log of vehicle information while driving. This log is usually stored in the SRS (air bag) module. This can be a useful tool to help them diagnose your intermittent problem.
I am sorry that I could not help resolve the problem with your truck, but if you have any new information related to this problem I'ld like to hear it to try and help find the cause of your problem.
Also if there is a solution found I'ld like to hear what the cause of this problem might have been.
If you have found any of this helpful, please feel free to leave feedback accordingly, Thank you
Just checking to see if there has been any solution found to your acceleration problem?
If there has been a solution I'l like to hear what it was
Hello and welcome to just answer, my name is ***** ***** Toyota master tech here to help you. cannot see or hear your vehicle so I rely on your input to my questions so I can help you better. I read your questions and notes that have been done . There are three things that an engine needs to operate properly (1) spark, (2) fuel , (air). So reading your notes you have spark, so now we can look at fuel and air. Because you have no codes we will focus on none sensor areas. How many miles are on the Tundra? Have you had it tuned up recently?
Aw I'm sorry I must of missed that what you said it was going on that long. I will give you a link to show you what to do to check if you have a bad pedal sensor and if you do it should be covered by Toyota as it was a safety recall. https://www.youtube.com/watch?v=TR-3nMD-f6U
