2007 tundra with 5.7v8 lack of acceleration "vsc off" light flashing traction control light on check engine light on

The warning lights can be connected - the traction control uses the engine to function, so if one system is acting up it can affect other systems.
You would need to have the engine and body computers scanned for trouble codes to proceed.

Seeing as how you go to a dealer vs: a repair
shop,take it back to the dealer

What else can you do?

You can not resolve yourself without factory service
& diagnostic manuals,you could purchase them

I currently have the same issue on my 2008 Tundra. I have noticed that one of the 12v acces plugs don't work. The problem is intermittent and started when the air was damp or after it rained. Now the same lights are on, the 12v doesn't work and the remote door locks don't work. Toyota want to run a diagnostic check at $125 an hour. Did you solve your problem?

no , it will not hurt it vsc=vehicle-stability-control its wont haver traction control so it will spin the tires easier when its wet/snow

Blinking your now in limp mode Your looking at the APP for the souce of fault. Once the APP has detected a fault your VDIM( vehicle Dynamics Intergrated Management system controls function such as ABS, w/EBD,BA,ECB,HAC,TRAC and VSC this allow operation together. ) gets disabled. Have the APP sensor troubleshooted. it is part of throttle pedal assembly and is not serviceable.

Hello you can guess this might be one of several switch malfunctions but a guess would be a waist of money and unnecessary repairs.The best solution you will need to go in to a garage and have a scan performed this will pin point the problem and you can repair the fault exactly with a guess.Most garages charge 425.00 to $75.00 dollars for these scans.

The key of your problem is to know what is the check engine light, there is several codes that send the computer to safe mode diminishing engine output, vsc and track off come with the check engine light.

try to unplug the nagtive battery for 15 min.

I would suggest having your mechanic scan the computer for viable trouble codes. WIthout that information, it is hard to determine the exact cause of your problem.

However, my experiences with the Tundra leads me to suggest that you have a bad Mass Air Flow Sensor...A concise scan and any codes would alow us to really help you out a lot better.

check air filter for dirty , how many miles or kms have your car? , maybe need to replace spark plugs, try to reset the ecu for a momentany malfunction, remove the negative battery terminal few minutes and reconnect,start engine and drive, check if lights goes off , please write me
