1. What is a California Smog Check?
A smog check is an emissions test required by the California Bureau of Automotive Repair (BAR) to measure the amount of pollutants your vehicle emits. The goal is to reduce air pollution by ensuring cars meet state emissions standards.
Types of Smog Checks in California
- Basic Smog Check: Standard test for most vehicles.
- Enhanced Smog Check: Required in high-pollution areas (like Los Angeles, San Francisco, and San Diego).
- Diesel Smog Check: For diesel-powered vehicles (1998 and newer, or with a GVWR under 14,000 lbs).
- OBD-II Test: For vehicles model year 2000 and newer, using the onboard diagnostic system.
Most Mitsubishi vehicles will undergo a basic or OBD-II smog check, depending on the model year.
2. Why is a Smog Check Required for Mitsubishi Vehicles?
California has the strictest emissions laws in the U.S., and all gasoline-powered vehicles (model year 1976 and newer) must pass a smog check. Mitsubishi vehicles, like all cars, must comply to:
- Reduce air pollution (carbon monoxide, nitrogen oxides, hydrocarbons).
- Improve public health by minimizing smog-related respiratory issues.
- Ensure vehicles are running efficiently and not wasting fuel.
Exemptions
- Electric vehicles (EVs) like the Mitsubishi i-MiEV.
- Hybrids (but some may still require testing).
- Gasoline-powered vehicles older than 1975.
- Diesel vehicles older than 1997 or over 14,000 lbs GVWR.
If your Mitsubishi is 8 years old or newer, you may be exempt from biennial smog checks (but still need one when selling).
3. How Often Do You Need a Smog Check?
The frequency depends on your vehicle type and location:
| Vehicle Type | Smog Check Requirement |
|---|---|
| New Mitsubishi (first 8 years) | No smog check (unless selling) |
| Mitsubishi (8+ years old) | Every 2 years (biennial) |
| Change of ownership | Required before sale |
| Out-of-state vehicle registration | Required upon registration |
You’ll receive a DMV notice when your smog check is due.

5. What to Expect During a Smog Test
A typical Mitsubishi smog check includes:
1. Visual Inspection
- Check for modified emissions parts (illegal modifications will fail).
- Ensure the catalytic converter, gas cap, and exhaust system are intact.
2. Functional Tests
- OBD-II Scan (2000+ models): Checks for error codes (e.g., P0420 catalytic converter issues).
- Dynamometer Test (pre-2000 models): Measures tailpipe emissions under simulated driving conditions.
3. Emissions Test
- Analyzes hydrocarbons (HC), carbon monoxide (CO), and nitrogen oxides (NOx) levels.
The entire process takes 20-30 minutes and costs $30-$80, depending on location.
6. How to Pass a Smog Check
Follow these tips to ensure your Mitsubishi passes:
✅ Drive Your Car Before the Test – A warm engine burns fuel more cleanly.
✅ Check the “Check Engine” Light – If it’s on, you’ll fail. Get diagnostics first.
✅ Use a Fuel System Cleaner – Helps reduce carbon buildup.
✅ Ensure Proper Tire Pressure – Needed for dynamometer tests.
✅ Change the Oil & Air Filter – Dirty oil increases emissions.
✅ Fix Any Exhaust Leaks – Can cause false high readings.
✅ Use Premium Gas Before the Test – Burns cleaner than regular fuel.
7. Common Reasons for Failing a Smog Test
If your Mitsubishi fails, common causes include:
❌ Check Engine Light On (automatic fail)
❌ Faulty Oxygen (O2) Sensor
❌ Bad Catalytic Converter
❌ Dirty Air Filter
❌ Rich Fuel Mixture (High HC/CO)
❌ Exhaust Leaks
❌ Old or Contaminated Engine Oil
8. What to Do If Your Mitsubishi Fails
If your car fails:
- Get a Detailed Report – The station must provide a failure report.
- Make Necessary Repairs – Common fixes:
- Replace O2 sensor ($100-$300)
- Fix exhaust leaks ($150-$500)
- Replace catalytic converter ($500-$2,500)
- Retest Within 30 Days – Some repairs qualify for a free retest.
- Apply for a Waiver (If Eligible) – If repair costs exceed $650, you may qualify for a waiver.
9. Tips for Maintaining Your Mitsubishi for Smog Compliance
- Follow the Manufacturer’s Maintenance Schedule
- Use OEM or CARB-Compliant Parts
- Avoid Aftermarket Tuning Chips (can cause emissions failures)
- Keep Your Gas Cap Tight (a loose cap can trigger a fail)
