Toyota VSC light?

Question

2004 toyota 4runner v6 4wd
I changed my spark plugs, 4 last week (no problem driving several hours) and the last 2 today, driver's side rear 2, and an hour later the check engine light and VSC came on and it ran rough. I saw in some previous answers the VSC light will come on just because the check engine light is on.
I checked my wires and clicked the connector onto the coil tower a little better and the engine runs smooth again but the lights are still on. I only ran about 5 minute since then.


I also have a little hose from the back of the block to the a small square housing on the underside of the intake"Upper Deck" that I removed to get to the plugs. It slipped right off with the squeeze ring clamp still connected. I would call this rotted. I taped around the tube to make it thicker until I can get a new hose.

So should the light go off by itself if the loose electrical connector was the cause and is now fixed?
And where is the OBD connector?

Thanks
Jeff

Answer 1

The light should go off by itself if the computer determines that there are no current malfunctions. I would get that hose replaced. After that, you can reset the computer by disconnecting the battery for a few minutes (10 min) to be sure. The light will now only come on if there is still a problem.
