What Is a California Smog Check?

California requires most gasoline-powered vehicles to undergo periodic emissions testing to help reduce air pollution and improve air quality. A Smog Check evaluates your vehicle's emissions system to verify it is operating within state standards.

Our certified technicians perform thorough emissions testing using state-approved equipment, ensuring your inspection is completed accurately and efficiently.

We're a California Test & Repair Facility

Unlike a Test Only station, Westlake Independent Automotive is licensed as a Test & Repair facility. That means if your vehicle doesn't pass its initial inspection because of an emissions-related issue, we can diagnose the problem and perform the necessary repairs right here in our shop.

Instead of visiting multiple locations, you'll have one trusted team to handle the entire process—from testing and diagnosis to repair and retesting.

Because our technicians work with these manufacturers every day, we understand the emissions systems and common issues that can affect their performance. This specialized knowledge allows us to diagnose problems efficiently and recommend the right repairs when needed.

Common Reasons a Vehicle May Fail a Smog Check

A failed emissions test doesn't always indicate a major repair. Some common causes include:

  • Check Engine Light is illuminated
  • Faulty oxygen sensors
  • Catalytic converter problems
  • EVAP system leaks
  • Worn spark plugs or ignition components
  • Failed emissions monitors
  • Engine performance issues

If your vehicle doesn't pass inspection, we'll explain the results, identify the cause, and discuss your repair options before any work begins.

Thinking about heading to the dealership for your next service? Before you book that appointment, here are five questions worth asking yourself:  Will my car get the attention it really deserves? Dealerships often feel rushed and impersonal, with long lines and packed service bays. At Westlake Independent, we take the time to thoroughly inspect and care for your vehicle—because you’re not just a number on a service ticket. Will I actually see the same people each time? At dealerships, you never know who you’ll get. At Westlake Independent, our team is small, local, and here for the long haul. Customers love that they can count on familiar faces every visit. How clearly will I understand what’s going on with my car? Nobody likes confusing checklists or vague explanations. That’s why we send you a digital inspection with photos and notes—so you see exactly what we see. Will this visit fit into my life—or disrupt it? Dealerships often leave you waiting or arranging your own ride. We make it easy with courtesy shuttles, on-site rentals, and even concierge pick-up and delivery when you need it. Am I supporting a business that values relationships—or just numbers? Dealerships often work toward corporate goals and quotas. Since 1988, Westlake Independent has been family-owned and deeply rooted in the Conejo Valley. Our focus is on building trust, caring for our neighbors, and keeping your vehicle reliable for the long run. At Westlake Independent Automotive, we welcome these questions—because our answers are what set us apart from the dealership.
