Garage Gurus | Volumetric Efficiency Testing

Performing a volumetric efficiency test is helpful when diagnosing engine issues with a vehicle. Designed to measure the engine’s ability to breathe and use air, volumetric efficiency testing reveals the accuracy of the mass airflow sensor and can expose engine issues like intake restrictions and exhaust flow restrictions. In this video, Master Trainer John Dixon of Garage Gurus takes you step-by-step through the process of executing a volumetric efficiency test.

John starts by showing how to set up your scan tool and how to qualify the mass airflow sensor before taking the vehicle for a drive. Using the data gathered on the drive, he then takes you through the math of the equation for determining the volumetric efficiency showing how to compute each step of the formula. Once John arrives at the results, he explains how to use it to determine possible engine problems. Count on Garage Gurus to help you get your vehicle repair done right.
