LEARNING OBJECTIVE
This training event provides technicians with alternative methods for diagnosing driveability concerns
using scan tool data and oscilloscope waveform analysis. Course content includes using scan tool features to analyze Short-Term and Long-Term Fuel Trims (STFT / LTFT), Single Edge Nibble Transport (SENT) sensor signals, narrowband and wide-band oxygen sensors and circuits, and fuel system controls / actuators. Oscilloscope setup procedures are covered in depth to obtain waveform measurements and further isolate complex drivability concerns present under various engine operating conditions.
