Hi, recently I've seen that on my 2007 Lexus RX350, there's the engine check light as well as the VSC light that comes up on the dashboard. What do I do or need to get changed in order to fix that problem?

 

Did you just fill up the car? Make sure your Gas Cap is on tight. If that doesn't fix it then you will have to get the Check Engine code read.

 

How many miles do you have on your RX350? High mileage Lexus (and Toyota) have this problem when O2 sensors start failing.

Have you also checked for any leaks in your exhaust manifold or engine intake manifold? A leak in the engine intake or exhaust manifold can allow extra air which causes faulty readings with the O2 or MAF sensors. You'll also notice a drop in MPG

 

 

VSC is Vehicle Stability Control. Hence, you have some issues related to ABS/VSC module. Sometimes it's as easy fix as cleaning ABS sensor heads. Better off, obtain ABS CAN BUS capable scanner and read error codes associated with VSC MIL. That will be good starting point. Go to HFT, buy one, read codes, return it. Or keep it. They come handy.

 

The VSC light normally comes on with the check engine light. It doesn't mean there's necessarily an issue with the VSC system. For example, a cylinder misfire code will trigger both the check engine light and VSC light.

When the VSC and CEL BOTH come on, it's a general fault indicating a problem with the engine, power train, or with the sensors (commonly the O2 sensors).

I had this problem as well on a late 90s Toyota and that turned out to have been a bad oxygen sensor.

If you have an OBD II scanner, you can plug it into the port on the driver side and take a reading to determine what the issue is.
