Can a Car Pass Inspection with Check Engine Light?

Introduction

The check engine light (CEL) is a warning light that illuminates on your dashboard when your car’s engine control unit (ECU) detects a problem. The ECU is responsible for monitoring and controlling the engine’s performance, and when it detects a problem, it will illuminate the CEL to alert you to the issue.

There are many different reasons why the CEL can illuminate, from minor issues like a loose gas cap to major problems like a blown head gasket. In most cases, the CEL will illuminate when the ECU detects a problem that could potentially damage the engine or other components of the car.

Can a Car Pass Inspection with Check Engine Light?

The answer to this question depends on the specific state in which you live. In some states, a car can pass inspection with the CEL illuminated, while in other states, it is an automatic fail.

In states where a car can pass inspection with the CEL illuminated, the inspector will typically note the issue on the inspection report. However, they will not be able to diagnose the problem or fix it. If the CEL is illuminated, it is important to have your car inspected by a qualified mechanic as soon as possible to determine the cause of the problem and have it repaired.

In states where a car cannot pass inspection with the CEL illuminated, you will need to have the problem diagnosed and repaired before you can get your car inspected.

What to Do If Your CEL Illuminates

If the CEL illuminates on your dashboard, the first thing you should do is check your gas cap to make sure it is tight.

If the gas cap is tight, you should have your car inspected by a qualified mechanic as soon as possible to determine the cause of the problem.

The mechanic will use a diagnostic tool to scan the ECU for trouble codes. The trouble codes will indicate the specific problem that is causing the CEL to illuminate.

Once the mechanic has diagnosed the problem, they will recommend a course of action to repair the issue.

Conclusion

The CEL is an important warning light that should not be ignored. If the CEL illuminates on your dashboard, it is important to have your car inspected by a qualified mechanic as soon as possible to determine the cause of the problem and have it repaired.
