I have a 1990 civic. There service engine light came on. I get one blink. What is the error and how do I fix it?

You have a problem in the Oxygen Sensor circuit. First, check the pigtail connector for corrosion--don't use WD-40 or any cleaner on the connector. Second, reset the ECM. If this does not solve the problem, replace the Oxygen Sensor.
