VSC light and Check Engine Light On at same time 2003 RX300

I just traveled 180 miles to the beach and upon arrival, both lights came on. I looked in the manual and checked the suggested items such as the gas cap and then took to Jiffy Lube for a quick diagnostic. Nothing else was open to perform the check. Was told the O2 filter was bad but that it could just be cleaned and didn't need replacing. As for the VSC light, the manual said not to worry. Now that I have returned and both lights are still on I'm wondering the proper route to take for repairs or just resetting the lights.

    Yes I do mean o2. Upon researching on the 'net I found several people with the same issues. apparently the VSC is somehow related to the check engine light from what I gathered. However, they also suggested checking the hose behind the air filter if that had recently been changed... which it has when the oil was changed. Can an o2 just be cleaned or reseated and why would Toyota/Lexus have those 2 lights illuminate at the same time??

Why is the engine light and VSC light on in my 2003 Highlander with 136,000 miles.


There is some of a sensor attached to the oil filter assembly, sometimes after regular oil change mechanic forgets to check this connection. So no harm to the engine, but the light stays on. Just ask them to re-connect.
Happened to my Highlander like 5 times :)

Car sat in parking lot for 3 days, with a lot of rain. Upon start up Check Engine & VSC began to flash. Car ran normally for 2 miles. Pulled over shut down car, waited 10 seconds re-started engine...


It likely had water on the ignition system. The check engine light will flash for misfire. The VSC light is on just because the check engine light is on. You likely have it dried out now and its fine. You just need to clear the codes. Autozone will do this for free.

VSC means Vehicle Stability Control.

It comes on when the sensor send a signal that the vehicle is not stable on the ground.....check the wheel balancing and alignment and the air pressure of your tires too.
