If the OBD2 fuse is blown, emissions tests will not work properly, as the vehicle’s emissions data cannot be read. This can result in a failed emissions test and ultimately lead to the vehicle being unable to pass inspection.

It’s essential to address the blown fuse before attempting an emissions test to ensure accurate readings. Without proper communication between the vehicle’s systems and the emissions testing equipment, the results may be inaccurate and lead to potential issues with compliance.

Addressing the blown OBD2 fuse promptly will help ensure the vehicle meets emissions standards and can pass inspection without any complications.

Frequently Asked Questions For Would Emissions Test Work If Obd2 Fuse Is Blown

Can A Blown Obd2 Fuse Affect Emissions Test Results?

Yes, a blown OBD2 fuse can affect emissions test results. When the fuse is blown, the onboard diagnostic system cannot communicate with the emissions control system, leading to an incomplete test. It is important to replace the fuse before undergoing an emissions test for accurate results.

What Are The Symptoms Of A Blown Obd2 Fuse?

Symptoms of a blown OBD2 fuse include the check engine light not illuminating when turning the ignition on, the inability to connect to the OBD2 scanner, and the emissions test not completing. If you experience any of these symptoms, it is likely that your OBD2 fuse is blown and needs to be replaced.

How Do I Know If My Obd2 Fuse Is Blown?

To check if your OBD2 fuse is blown, use a fuse tester or a multimeter to test the continuity of the fuse. If the tester indicates an open circuit or the multimeter shows no reading, it means the fuse is blown.

Additionally, visual inspection can also help identify a blown fuse, such as a broken filament or discolored appearance.

Can I Still Drive My Vehicle With A Blown Obd2 Fuse?

Yes, you can still drive your vehicle with a blown OBD2 fuse. However, it is important to note that driving with a blown fuse may result in inaccurate diagnostic information and prevent you from passing an emissions test. It is recommended to replace the fuse as soon as possible to ensure the proper functioning of the emissions control system.


If the OBD2 fuse is blown, it can negatively impact the emissions testing process. Without a functioning fuse, the onboard diagnostic system cannot communicate with the emissions control devices, leading to inaccurate test results. It is crucial to ensure the fuse is in good condition to ensure the effectiveness and accuracy of emissions testing.

Proper maintenance and regular fuse checks are essential to ensure compliance with emissions regulations and minimize air pollution.
