Can Car Pass Emissions with Check Engine Light On?

Introduction

The check engine light is a warning light that illuminates on the dashboard of a vehicle to indicate that there is a problem with the engine or emissions system. When the check engine light is on, it means that the vehicle’s computer has detected a fault that needs to be addressed.

In some cases, the check engine light may be illuminated due to a minor issue, such as a loose gas cap. However, in other cases, the check engine light may indicate a more serious problem, such as a faulty catalytic converter or oxygen sensor.

If the check engine light is on, it is important to have the vehicle inspected by a qualified mechanic as soon as possible. The mechanic will be able to diagnose the problem and make the necessary repairs.

Can a Car Pass Emissions with the Check Engine Light On?

The answer to this question is: it depends. In some states, it is illegal to drive a vehicle with the check engine light on. In other states, it is permissible to drive a vehicle with the check engine light on, but the vehicle may not pass an emissions test.

The emissions test is a test that measures the amount of pollutants that are emitted from a vehicle’s exhaust system. In order to pass an emissions test, the vehicle must meet certain emissions standards.

If the check engine light is on, it is likely that the vehicle will not pass an emissions test. The reason for this is that the check engine light indicates that there is a problem with the engine or emissions system. This problem may cause the vehicle to emit excessive pollutants.

What to Do if the Check Engine Light Is On

Once the repairs have been made, the check engine light should turn off. If the check engine light remains on, it is important to have the vehicle inspected by a mechanic again to ensure that the repairs were successful.
