engine light is on

Hi, this is Bo, an auto expert on RepairPal's Car Genius team! If the check engine light is on in your 2002 Lexus SC430 and it’s hanging out near the tire indicator, that’s your car’s way of saying, “Hey, something’s not quite right under the hood.” Even if it’s running fine, the light could be triggered by anything from a loose gas cap to a failing sensor. Since it’s been on for a week, your best move is to get the codes scanned. Most auto parts stores will do it for free. Once you have the code(s), you’ll know whether it’s something simple—like an EVAP leak—or something that needs more attention, like an O2 sensor or catalytic converter issue. Ignoring it too long could lead to bigger problems or a failed emissions test, so don’t let it become dashboard wallpaper.
