Can a Car Pass Inspection with the Check Engine Light On?
What is the Check Engine Light?
The check engine light is a warning light that illuminates on the dashboard of a car when the engine control unit (ECU) detects a problem with the engine or its emissions systems. The ECU monitors various sensors and systems in the car, such as the oxygen sensors, catalytic converter, and fuel injection system. When a problem is detected, the ECU will illuminate the check engine light to alert the driver that something is wrong.
Can a Car Pass Inspection with the Check Engine Light On?
The answer to this question depends on the state in which you live. In some states, a car will not be able to pass inspection if the check engine light is on. In other states, the car may be able to pass inspection, but the inspector will note the presence of the check engine light and may recommend that the problem be fixed before the next inspection.
What to Do if the Check Engine Light Comes On
If the check engine light comes on, it is important to have the problem diagnosed and repaired as soon as possible. Ignoring the check engine light can lead to more serious problems down the road. Here are some steps you can take if the check engine light comes on:
- Check the gas cap. A loose or missing gas cap can cause the check engine light to come on. Tighten the gas cap and see if the light goes off.
- Have the car scanned for codes. An auto parts store or mechanic can use a code reader to scan the car’s computer for trouble codes. These codes can help identify the cause of the check engine light.
- Fix the problem. Once the cause of the check engine light has been identified, it is important to have the problem fixed as soon as possible. Ignoring the problem can lead to more serious problems down the road.
Conclusion
Whether or not a car can pass inspection with the check engine light on depends on the state in which you live. However, it is always important to have the problem diagnosed and repaired as soon as possible. Ignoring the check engine light can lead to more serious problems down the road.
