Engine Light, TRAC OFF, VSC Track Light all went On on my 2004 Toyota RAV4.

put a new gas cap, or tighten the old one correctly, have the codes erased and see what happens

Yes, tightened it.. code erased by advanced, all lights went off. No issues today..thank you!!

Can you just take off battery cable tireder?

Yes

i had the VSC trac & check engine light on .. my mechanic played with gas cap and the lights went off for a week now theyre back on... can someone help

Same here. have driven like that for almost 2 years without any problems.

Has anyone had the sensor for the VSC replaced, as my mechanic changed the gas cap and apparently did something to the piece that reaches up to the gas cap, but the light went back on when a made a quick turn, as it had initially.

My car drives fine with both lights on however I cant pass inspection in New York state! Can anyone help ke get the vsc trac and check engine lights off???

What I noticed with mine is that when I’m on the highway the lights don’t come up, but when I’m around town driving under 50mph is when it seem to always happen.

2007 lights were on due to vacuum tube disconnect. Dealer service put the tube on as intended and all is OK.
