How to Easily Reset Check Engine Light After Replacing Purge Valve
As I was driving home from work a few weeks ago, the dreaded check engine light illuminated on my dashboard. I knew it was only a matter of time before this happened, as my car had been running rough and was having trouble starting lately. I took it to my mechanic, and he told me that the problem was the purge valve. He replaced the valve for me, and the car was running much better. However, the check engine light was still on. I asked him how to reset the check engine light, and he told me to follow these steps:
1. Turn the ignition to the “on” position, but do not start the engine.
2. Press the gas pedal all the way down and hold it for 10 seconds.
3. Release the gas pedal and turn the ignition to the “off” position.
4. Wait 10 seconds.
5. Turn the ignition to the “on” position and start the engine.
Why Does the Check Engine Light Stay On After Replacing the Purge Valve?
The check engine light is designed to illuminate when there is a problem with the vehicle’s emissions system. The purge valve is a part of this system, and when it is replaced, the computer needs to be reset so that it can recognize the new valve and turn off the check engine light.
