Diagnostics by the Numbers presented in person by Jeff Bly Sponsored by NAPA Auto Parts & NAPA Autotech Training
Learn what the Mass Air Flow Sensor (MAF) should read at any idle RPM, on any vehicle, as well as what the MAF should read at wide open throttle (WOT), using volumetric efficiency calculator methods & simple, real world, scan data analysis. b Learn how the MAF effects Fuel Trim numbers, the exact amount of fuel volume any
specific engine requires, and how to quickly decode the scan data to find faults quickly & easily. b We'll also review exactly what to expect from the front & rear oxygen sensors, not only as it applies to catalyst efficiency, but also how you can use those numbers to verify fuel control. v This class is for novice to advanced diagnosticians looking to fine tune their skills.
