What Is a DEQ Inspection?
A DEQ inspection, conducted by Oregon’s Department of Environmental Quality, is an emissions test that evaluates your vehicle’s environmental performance. If you live in certain areas of Oregon—like Clackamas County where Lake Oswego is located—your vehicle may be required to pass this inspection to be eligible for registration renewal.
The DEQ inspection focuses on your vehicle’s emissions system, looking for excess pollutants or malfunctions in key components such as the catalytic converter, oxygen sensors, and evaporative emissions systems. If your car doesn’t meet the required standards, it won’t pass, and you’ll need to get the necessary repairs before attempting a retest.
Common Causes of DEQ Inspection Failure
Failing a car emissions inspection isn’t uncommon, and most problems can be resolved quickly by professionals who understand the system. Some of the most common reasons cars fail include:
-
Check engine light is on
-
Faulty oxygen (O2) sensors
-
Leaking or damaged EVAP system components
-
Worn spark plugs or ignition coils
-
Failed or clogged catalytic converter
-
Loose or missing gas cap
-
Incomplete emissions system readiness (often due to battery disconnect or recent repairs)
Our experienced technicians at Accurate Auto Repair can inspect, diagnose, and resolve these issues, ensuring that your vehicle passes its DEQ retest.

Frequently Asked Questions (FAQs) About DEQ Service & Repair
What is the purpose of a DEQ inspection in Oregon?
A DEQ inspection ensures your vehicle meets Oregon’s emissions standards. It helps reduce air pollution and is required for vehicle registration in certain counties, including Clackamas County.
How do I know if my car needs a DEQ inspection?
If your vehicle is registered in a DEQ-required area and is gasoline-powered and newer than model year 1975, it likely needs testing every two years. Check your DMV renewal notice or the DEQ website for confirmation.
Can I clear the check engine light to pass the test?
No. Simply clearing the check engine light without fixing the problem won’t help. The DEQ also checks system readiness. If your car hasn’t completed enough drive cycles, it may be marked as “not ready.”
How long does a DEQ repair take?
Many repairs—like gas cap replacements or O2 sensors—can be done same-day. More complex issues like catalytic converter or EVAP repairs may take longer. We’ll provide a time estimate upfront.
Do you handle DEQ waivers if I can’t afford the repair?
Yes, if your repair costs exceed DEQ waiver thresholds and you qualify, we’ll help you prepare documentation for a potential waiver request through Oregon’s Department of Environmental Quality.
Can I drive my car if it fails the DEQ inspection?
Yes, but you cannot renew your registration until the emissions-related issues are resolved and your vehicle passes a retest.
