The check engine light appears when the vehicle detects a concern in an engine-management or emissions-related system. Causes vary, and a stored trouble code points to an area for investigation rather than automatically identifying a part that needs replacement.
A steady light and a flashing light can call for different responses. If the light flashes or the vehicle runs roughly, loses substantial power, or behaves abnormally, stop safely and follow the manual's instructions before continuing.
Record when the warning started and avoid erasing diagnostic information before the concern is checked. Contact Oxford Automotive Tire & Repair Sunbury with the symptoms and any recent refueling, maintenance, or repairs.
