Need more information - what is meant by 'my engine is blinking'? Are you referring to the check engine light? If yes, check the vehicle for fault codes to see if there are any sensors were involved to the malfunction of the engine.
1.Local auto parts stores such as Autozone ( not in California) or Advance Auto parts will scan and retrieve any diagnostic trouble codes ( dtc ) stored in the powertrain control module for free of charge..
2. Amazon.com has the code reader for less than $20.00 dollars.
3.Re-post the dtc's in here " answer question " for further assistance.
Note: we need the dtc's to identify the sensor, there are a dozen different sensors to operate the car.
Visit this site and see all the different sensors.
