A flashing check engine light indicates a serious engine problem. You should pull the vehicle to a safe location, turn off the engine and have it towed to a repair facility. A check engine light that illuminates intermittently or remains illuminated can indicate a wide variety of problems. The diagnostic code helps to narrow the troubleshooting process.

The S10メs onboard computer system constantly scans the operation of the engine and makes adjustments to maximize the vehicle's operation. If it detects a problem that causes the engine to operate outside of the manufacturerメs specifications, it illuminates the check engine light. Sometimes the cause of the issue is relatively simple. If you do not tighten the gas cap after fueling the tank, the excess air in the fuel system causes the light to send a warning. At other times, the computer detects a major problem. Using diagnostic codes to determine the issue may lower repair costs by ruling out issues that cause similar problems in engine performance.
