Course Description:

Although gasoline is the most commonly used fuel, several alternative flex-fuels can be used in some of today’s vehicles. Diesel fuels contain less amounts of sulfur and this allows the introduction of many new clean-burning diesel engines and biodiesel fuels. Air/fuel ratios are affected by octane rating and fuel trim will react accordingly. Monitors and Mode $06 are essential diagnostic tools that can help identify difficult drivability concerns by looking at the results of the PCM tests on the various emissions systems. Beginning July 1, 2019, 2010MY and newer vehicles with an OBD II Permanent Diagnostic Trouble Code (PDTC) stored in the vehicle’s computer memory will fail the BAR-OIS Smog Check. This additional check increases existing inspection requirements and failure criteria for OBD II vehicles. Understanding PDTCs and the process to delete codes stored in permanent memory is an essential skill to verify emission repairs are successful.

Course Objectives:

Upon completion of this course the student will be able to:

  • Explain air-fuel ratios, normal/abnormal combustion, and octane rating.
  • Explain alternative fuel vehicles and discuss the safety procedures when working with alternative fuels.
  • Discuss E85, methanol, propane, CNG, LNG, and P-series fuels.
  • Discuss synthetic fuels and compare diesel, biodiesel, and E-diesel fuel
  • Explain the purpose and function of fuel trim and compare STFT and LTFT.
  • Discuss the difference between speed density and mass air flow fuel control.
  • Explain how the PCM determines base injector pulse width.
  • Describe how volumetric efficiency can help diagnose performance concerns.
  • List and explain common OBD II Monitors
  • List the steps for diagnosing drivability concerns using Mode $06.
  • Explain how to convert Mode $06 raw numbers to usable data.
  • Explain new PDTCs regulations for MY2010 and newer vehicles
  • Access and follow Universal Drive Pattern procedures to erase permanent memory trouble codes and/or manufacturer dedicated monitor cycles.
