Question about 2006 Toyota Sienna

Toyota error code P2118

I jump started my 2005 toyota Sienna and accidentally reversed the jumper cables. All the engine dash lights come on and the gas pedal would no longer work. My OBD II had error code P2118 and P2118 P. I have since replaced the battery and the 10A fuse for the throttle motor and the gas pedal now works but the dash lights icons are still staying on.

    Where is the dash cluster and the diode. Is it a part I can just buy and replace it?

I don't have a Sienna but I do have a 2008 Toyota Camry SE. After it being in the garage for many months, 8 months I think, I had to give the battery a jump to finally start it up. Well The jumper cables I used weren't that great. They flickered and seemed to smoke a little. So i removed them and put a better set on to get a charge. I didn't think anything of it. After that charge came through and i was able to accelerate at all... The throttle was to the floor and the car would not even go up .5 RPMs... After several days and talking to the dealer, I was about to call a Tow to have it taken to the dealer. Luckily my friend came by with one of those diagnostic readers and it spit out the P2118 error code. Immediately we looked it up and found this site. Thanks to Fixya.com I was able to determine that it was a freakin measly fuse that blew due to bad jumper cables... Thank god for the Fuse and thank you to Fixya.com that I was able to determine this so quickly!!!

    Another round of thanks to you guys on Fixya.com. Some helpful young men said they'd be glad to jump start my wife's 2007 Camry V6. As above, the first cables kind of sizzled. The second set was successful in getting the car started. Several minutes later, wife had to drive home maxed out at 20 mph.
    I replaced the 10A fuse and we're good to go.
    On a side note, the fuse map on the inside lid of the fuse box didn't match the layout of the fuses, but believe it or not, there was an accurate map and circuit listing in the owners manual.
    Thank you again!

    Hi all:

    Thanks for the tip on this! I did the same ******** move as everyone else. Couldn't see the markings on the battery properly because it was so badly corroded and it was pitch black out. Anyway, replaced the 10A fuse and all was good. I'd like to add a little more information for anyone in trouble:

    The fuse is located in what Toyota calls the Engine Room Junction Block. It's the big black box on the right side of the engine compartment behind the battery. Pop it open to get the offending fuse. The 10A fuse you're looking for is in the upper-left corner. There are 2 relays to the left of it and 20A fuse to the right of it. If you are in a tight spot and need to get back on the road without a spare fuse, use the 10A fuse in the same row, second from the right. It goes to the horn. You'll need to replace it as soon as you can, but at least you'll be on your way.

    FYI, Toyota's official name for the throttle body control system is the ETCS or Electronic Throttle Control System. You might come across the acronym if you're searching literature on the subject. Also, I was able to get the "Check Engine" light to go out by disconnecting the battery AFTER replacing the fuse. I'm guessing the system does a complete status check when it gets power re-applied and will find all is well.

    Thanks again to all contributors. Saved my *** big time!

Do this: Take off the positive terminal for the battery, and leave it off for about 1-5 minutes. After atleast 1 minute, reconnect the battery terminal, and the code should be cleared!

I also ran into this issue with my 2012 Toyota Camry. I attempted to get the battery recharged and the guy crossed the cables. I was told I would have to get the computer reset and almost towed it in. Like others, could not increase MPH over 15. Saw this post, decided I could give it a try and it worked!!!

Just want to post here that the details of changing this fuse were exactly what I needed to know to fix the same issue on my 2008 Camry after trying to jump it with a car start box (Stanley Fat Max-didn't work but was connected properly). I can read the codes but didn't know what to do until I stopped here at Fixya and read your posts. So a big THANK YOU to everyone for saving me time and money!

I have a 2010 Toyota Corolla and I had check engine light come on 3 x. The 1st was because I left the gas cap untighten per dealer. The 2nd I took it to advance auto because as I was making a turn my check engine came on and suddenly I could not increase speed almost getting hit by another car. It stated it was the throttle. I took it to the dealer they stated I needed a new battery so I bought one. today the light came on again and I had to sit with the car off to see if the ilde would go down finalyy it did and i was able to drive slowly to my destination

No acceleration gas pedal


Sorry to say, sounds as if you had cables hooked up backwards, or possibly just had very poor connection between battery and battery cable terminal. If you may have had jumper cables connected backwards, you may have fried some electrical component. Get someone to read the codes which are making the check engine light come on, and perhaps this will give a clue as to what component is blown. Could have damaged anything from a small sensor to the main computer, in which case I would check with salvage yard for a used unit. The main computer is quite pricey.

2005 nissan murano jump started witnow it will only idle but will not accelerateh jumper cables reversed


NOT SURE WHAT YOU SAYING ? WHEN GETTING JUMP STARTED, THE BATTERY FROM THE GOOD VEHICLE MUST PLACE JUMPER CABLES ON BATTERY TERMINALS, THE CAR BEING JUMPED, YOURS, THE (+) TERMINAL IS JUMPED FROM GOOD BATTERY, THEN THE (-) JUMPER CABLE FROM GOOD BATTERY GETS CLAMPED TO YOUR CARS FRAME OR ENGINE BLOCK, NOT YOUR DEAD BATERY !!!!!!! YOU MAY HAVE SHORTED SOMETHING OUT, MAYBE EVEN YOUR COMPUTER CHIP IN THE ECM ! YOU NEED A MASTER TECH TO HELP YOU ON THIS ONE, I WOULD'NT TOUCH THIS WITH A TEN FOOT POLE ! SORRY, I COULD BE WRONG, BUT, NOT AN EASY ISSUE OVER THE NET !!!!!!

My 1990 mercury grand marquis was boosted wrong


Might need to check the main circuits for a blown fuse or fuseable link.
There is a fuse wire between the alternator and battery.

I just changed my battery, alternator on my 2006 toyota sienna(4 cylinder) and when i put my foot on the gas pedal, the engine shut off. I had several jump starts but the battery light stays on. also when...


Check and make sure you have all your connectors and cables tight. Also check to make sure your alternator fuse didnt blow, it has a seperate fuse from the battery and if blown it will cause this problem.
