What Is a DEQ Inspection?

A DEQ inspection is an emissions test required by Oregon’s Department of Environmental Quality to ensure your vehicle meets air quality standards. If you live in Tigard or other parts of Washington County, your vehicle must pass this inspection to renew its registration. The test checks whether your car’s onboard diagnostic system (OBD-II) and emissions control components are working correctly and within legal emission limits.

If your vehicle fails, you’ll receive a report indicating the issue. Before you can renew your registration, those problems must be resolved. Accurate Auto Repair is here to make that process easy.

Common Reasons Vehicles Fail Car Emissions Inspections

Many vehicles fail car emissions inspections due to issues that are simple to identify and fix—especially if caught early. Some of the most common causes of a failed DEQ test include:

• Check engine light is on
• Faulty oxygen (O2) sensor
• Evaporative emissions (EVAP) system leak
• Worn-out or failed catalytic converter
• Loose, cracked, or missing gas cap
• Malfunctioning mass air flow sensor
• Incomplete readiness monitors (due to recent battery reset or repair)
• Misfires, bad spark plugs, or ignition system issues

At Accurate Auto Repair, our ASE-certified technicians use advanced diagnostic tools to pinpoint the exact reason for your vehicle’s failure and recommend only the repairs necessary to help it pass.

Frequently Asked Questions (FAQs) About DEQ Inspection

What is included in a DEQ inspection?
DEQ inspections in Oregon include a connection to your car’s onboard diagnostic system (OBD-II). The test checks for emissions system trouble codes and ensures all emissions monitors are in a “ready” state.

Can I drive my car if it fails a DEQ inspection?
Yes, you can continue to drive your car temporarily, but you will not be able to renew your registration until the issue is resolved and the vehicle passes a retest.

What should I do after failing a DEQ inspection in Tigard?
Bring your failure report and your vehicle to Accurate Auto Repair. We’ll run diagnostics, identify the problem, make the necessary repairs, and help you get ready for a successful retest.

How long does it take to complete DEQ repairs?
It depends on the issue. Many common repairs like replacing sensors or fixing a gas cap can be done same-day. More complex issues like catalytic converter replacement may take longer.

Do I need to complete a drive cycle after repairs?
Yes. Your vehicle must complete specific driving conditions (a drive cycle) so the emissions system can reset its monitors. We perform these for you or guide you on how to do it correctly.

Do you help with DEQ waivers if my car can’t be repaired?
Yes. If your repair costs exceed the DEQ’s waiver threshold and your vehicle still fails, we’ll help you apply for a waiver through Oregon’s Department of Environmental Quality.
