2003 Toyota Tundra Accelerator

  • V8
  • 2WD
  • 10,300 MILES
So I left the dome light on overnight in my 2003 Toyota Tundra, and needless to say it ran the battery down. I accidentally crossed the jumper cables on the car I tried to use to jump my truck (no joke. It was dark, I was in a hurry and connected the positive cable to the negative post and vice versa). So I used the seccond car that day, and jump started the truck that evening. I let it run for about ten minutes to charge the battery, turn it off, let it sit for a couple minutes then started it back up to make sure the battery held the charge. Everything seemed to work fine.

The next morning I go out start up the truck, put it in gear (auto transmission), and discover the accelerator no longer works. The truck will go into all gears and will move forward and reverse, but it will not accelerate. The check engine light is now on, and the transmission is rough when I shift into reverse (reverse only; drive is a smooth transitiion) as well. Did I short out an electrical sensor / transmitter? Is the problem the transmission or the accelerator? Any / all help will be greatly appreciated.

Wow this is may be fun to track what happened just so you know this upfront ok. First off never jump start these newer cars with another car use a jump box ok. Next never use the altinator to charge the battery as that is not the disign of an alternator it is ment to maintain and keep up with the demand of the system with a fully charged battery. THe old day of generators this was ok but not any more as these alternators are high amp and get very hot and can cook them. So it maybe fine this time but not in the future.
Now as for what happened it may have fried the computer so what I need to know is weather or not you have digital multi meter and with the check engine light on can you get it to your local parts store for a scan? Call first make sure they do a free scan. Get back to me with what you can and we will take it from there.
