Correct Failed Emissions with Reliable Auto Services at Twin Peaks Auto Repair

If your car recently failed emissions, you’re not alone. Many Colorado drivers experience this at some point, especially as vehicles age. While it can feel inconvenient or stressful, the good news is that most issues are fixable with the right auto repair and proper auto maintenance. At Twin Peaks Auto Repair, your trusted ASE Certified auto repair shop in Longmont, CO, we help drivers get back on the road quickly with reliable emissions services and expert diagnostics.

Below, we break down what to do next, why emissions failures happen, and how to prevent them in the future.

Don’t Panic—Review the Emissions Report

When your car fails, the testing station provides a detailed report outlining the problem areas. This report gives clear direction on what needs attention. Bring this information with you when you visit an auto repair shop so technicians can quickly identify the cause and recommend the right auto services.

Schedule a Diagnostic Inspection

A “failed emissions” result is usually tied to one or more issues in your vehicle’s engine, exhaust, or onboard computer system. Common causes include:

• A faulty oxygen sensor
• Check engine light errors
• Damaged catalytic converter
• Exhaust leaks
• Worn spark plugs or ignition problems
• Evaporative emissions system leaks

At Twin Peaks Auto Repair, our ASE Certified technicians use advanced diagnostic tools to pinpoint the root of the failure. Accurate diagnosis saves you time, money, and return trips to the testing station.

Get the Necessary Auto Repairs

Once the issue is identified, the next step is completing the needed auto repair. Depending on your vehicle’s condition, repairs may include:

• Replacing sensors
• Fixing exhaust system issues
• Correcting engine misfires
• Repairing EVAP system leaks
• Servicing or replacing the catalytic converter
• Updating or reprogramming your vehicle’s computer

Our team ensures repairs meet Colorado emissions standards so you can pass with confidence.

Perform Any Required Drive Cycles

Some vehicles need a “drive cycle” after repairs to reset monitors within the onboard computer system. This involves driving your vehicle under specific conditions, speed, temperature, and time, so the system can run its internal tests. If this step is skipped, your vehicle may not be ready for retesting, even after repairs.

Twin Peaks Auto Repair can advise you on the proper drive cycle for your make and model.

Return for a Retest

After repairs and drive cycles are completed, it’s time to return to an emissions testing station. In many cases, retesting is offered at a reduced cost or even free if done within a certain timeframe. Check your inspection notice for details.

Keep Up with Routine Auto Maintenance

Emissions problems often stem from neglected maintenance. Keeping up with scheduled auto maintenance not only improves fuel efficiency and performance but also reduces the likelihood of failing future emissions tests.

Regular maintenance that helps prevent emissions issues includes:

• Oil changes
• Air filter replacements
• Spark plug and ignition service
• Fuel system cleanings
• Exhaust system inspections

Twin Peaks Auto Repair offers complete auto services to help keep your vehicle running clean and efficient all year long.
