A flashing Service Engine Soon or Check Engine light is a serious warning sign that there is a problem with your vehicle's engine. The most common cause of a flashing check engine light is an engine misfire, which can damage the catalytic converter. Other possible causes include:

      • Low oil pressure
      • Overheating
      • Fuel delivery problems
      • Emissions control problems

If the check engine light is flashing, you should not continue driving your vehicle. The problem could get worse and damage your car, or even cause a fire. Instead, you should take your car to a mechanic as soon as possible to have the problem diagnosed and repaired.

Here are some tips to help you stay safe if your check engine light starts flashing:

      • Pull over to the side of the road as soon as possible.
      • Turn off your engine and wait for it to cool down.
      • Do not restart your engine until you have had it diagnosed and repaired.
      • If you are unable to pull over to the side of the road, you can continue driving for a short distance, but only at a reduced speed.

It is important to remember that a flashing check engine light is a serious warning sign. If you ignore it, you could damage your car and put yourself and others at risk.
