What to Do When the Check Engine Light Comes on for Honda Civic
When the check engine light comes on in your Honda Civic, it can be alarming, but there are steps you can take to address the issue.
1. Check the Gas Cap:
– One common cause for the check engine light to come on is a loose, broken, or missing gas cap. This can reduce fuel pressure and allow fuel vapors to escape, affecting fuel economy and emissions.
2. Get the Vehicle Checked:
– It is recommended to get your Honda Civic checked as soon as possible when the check engine light comes on. Ignoring the warning could potentially lead to major damage to expensive engine components.
3. Assess the Situation:
– When the check engine light comes on, carefully check all gauges and indicators, especially those related to engine overheating or low oil pressure. If there are obvious signs of a major problem, pull over to a safe spot and turn off the engine.
4. Professional Inspection:
– While it may be tempting to quickly look at the car yourself and reset the check engine light, it is best to have a professional inspect it to ensure there isn’t an underlying problem.
5. Resetting the Light:
– If you’ve addressed the issue causing the check engine light to come on, you can try resetting the light manually. This can be done by disconnecting the car’s battery for a few minutes or using an OBD II scanner to clear the codes. However, it’s important to note that resetting the light doesn’t address the underlying issue causing it to come on.
