Hello, thanks for posting

The check engine light turning on will also cause the vs/.trac lights to illuminate this is because these systems are disabled while the check engine light is on. The main concern is the check engine light at this time, do you have the code number information available? Has the car recently been serviced?

Check the vacuum hose coming from below the firewall to the side of the air filter housing, this is an evap system hose and it may be disconnected.
