Vsc flashing and traction control on.

this happened today and yesterday and i’m confused. read it is the #7 cylinder. just worried to put money into the truck if it is about to die.

 

Get the codes read. Autozone, etc will do it for free.

Report back here and someone knowledgeable will speak up.

 

is it a misfire?? like stated above check codes and give us a little more input.. Some questions before you go, have you changed the spark plugs?? When you identify cylinder 7 pull the coil pack and swap it with the coil next to it and restart to see if anything changes, so you may get a better answer like that coil pack is dead.

 

It seems like the ECU triggers these along with a CEL.... I had both turn on for a crankshaft position sensor, and they had no relation.... May be a scare tactic to prevent the owner from driving it and preventing further damage. I just pulled it out of my ass, but when those lights came on it did scare the ish out of me... but I still moved it anyway....

 

So trip to dealership or autozone?

 

go to autozone where its free99, and take a small bag with a 12, 14, 10 (because I don't remember the coil's size but its probably a 12mm) and a ratchet so when you pull codes you can be ready to swap the coils and run a diagnostic again... if its under warranty, then let Toyota deal with it....
