The "check engine" light in a Chevy Tahoe is a sign that the onboard diagnostics have detected issues like an exhaust leak, misfire, or engine timing problem. It's important to address this promptly to avoid potential problems like overheating or catalytic converter failure. The warning could be as minor as a loose gas cap or more serious, such as excess unburned fuel in the exhaust system. While a flashing light might be due to a faulty spark plug, which is not urgent but should be replaced soon. Other potential triggers for the light include O2 sensor failure, a weak battery, or alternator issues. A professional service center can use an OBDII scanner to pinpoint the problem.
How much time should you keep the brakes engaged to allow the ABS light system to reset?
Typically, when the check engine light is illuminated, it's often related to a problem within the ABS system or the transmission.
