Can Your Car Pass Inspection with Check Engine Light On?

What is the Check Engine Light?

The check engine light is a dashboard indicator that illuminates when the engine control unit (ECU) detects a problem with the vehicle’s emissions control system. The ECU monitors various sensors throughout the engine and exhaust system to ensure that the vehicle is operating within acceptable limits.

Can You Pass Inspection with Check Engine Light On?

In most states, vehicles with a check engine light on will not pass inspection. The only exception is if the problem is related to an emissions control system component that is not required for the vehicle to pass inspection. For example, if the check engine light is on due to a faulty oxygen sensor, the vehicle may still pass inspection if the oxygen sensor is not required for the vehicle’s emissions system to function properly.

What to Do if Your Check Engine Light is On

If your check engine light is on, the first thing you should do is have the code read by a mechanic. The code will indicate the specific problem that is causing the light to illuminate. Once you know the cause of the problem, you can decide whether or not to have it repaired before taking the vehicle for inspection.

Consequences of Ignoring the Check Engine Light

Ignoring the check engine light can lead to serious problems down the road. The problem that is causing the light to illuminate could worsen over time, leading to more expensive repairs or even engine damage. In addition, driving with a check engine light on can lead to increased emissions, which can contribute to air pollution.

Conclusion

In most cases, vehicles with a check engine light on will not pass inspection. It is important to have the code read by a mechanic and have the problem repaired before taking the vehicle for inspection. Ignoring the check engine light can lead to serious problems down the road.
