Why Emissions Inspections Are Essential

Emissions inspections play a critical role in protecting public health and the environment.

These regular checks pinpoint repairs that can boost your vehicle's efficiency and cut down on harmful emissions.





Our Emissions Inspection Approach

At Moncur's Automotive, we conduct detailed emissions inspections using cutting-edge diagnostic equipment. Our certified technicians are trained to precisely measure your vehicle's emissions and pinpoint any compliance issues with state and federal regulations.

Emissions Inspection Checklist


Exhaust System Evaluation

We meticulously examine your vehicle's exhaust system for any leaks or faults that could impact emissions.

Emissions Control Systems Checks

We check your vehicle's emissions control mechanisms, such as the catalytic converter and evaporative emissions system, to ensure they are functioning effectively.

Onboard Diagnostics (OBD) Analysis

We perform an OBD test to confirm that your vehicle's computer system is operational and accurately identifying emissions problems.

Common Reasons for Failing an Emissions Test

Vehicles often fail emissions tests due to issues like defective oxygen sensors, catalytic converter problems, or faults in the evaporative emission control system. At Moncur's Automotive, we specialize in diagnosing and fixing these problems efficiently.

How to Prepare for Your Emissions Inspection

To ready your vehicle for an emissions test, ensure it is well-maintained and the check engine light is off. Driving for about 30 minutes prior to the test can warm the engine to the optimal temperature, potentially enhancing the outcome.

Highly recommend Moncur's Automotive!! A different place told my husband that our car needed the CV axels replaced and that it was a "hazard to drive." An expensive repair! He took our car to Moncur's Automotive to have it looked at. Kerry helped him out and told him that that there was absolutely nothing wrong with our car, and then would not accept any payment for a diagnostic fee. We're thrilled to have found an honest, reliable mechanic in the East Valley. If you need auto repair in Mesa, definitely give Moncur's Automotive a call!
