AUT 4011 - Engine Performance I


Clock Hours: 258

Delivery Mode
on-ground

Industry Certifications ASE Engine Performance certification

Course Description:
In this course students are taught to diagnose and repair today’s complicated engine and powertrain management systems. Topics include: general engine diagnosis, ignition systems, fuel and air systems, emissions systems, computerized engine controls, and engine electrical systems. Special emphasis is placed on the computer and the different systems it controls. The course prepares students for the Engine Performance Technician certification test administered by ASE.

Student Learning Outcomes:
Students will be able to demonstrate knowledge of:

A. General

  1. Research vehicle service information such as fluid type, vehicle service history, service precautions, technical service bulletins, and recalls including vehicles equipped with advanced driver assistance systems (ADAS).
  2. Retrieve and record DTC’s, OBD monitor status, and freeze frame data; clear codes and data when directed.
  3. Verify proper engine cooling system operation; determine needed action.
  4. Verify correct camshaft timing including engines equipped with variable valve timing (VVT) systems; determine needed action.
  5. Identify and interpret engine performance concerns; determine needed action.
  6. Diagnose abnormal engine noises or vibration concerns; determine needed action.
  7. Diagnose the cause of excessive oil consumption, coolant consumption, unusual exhaust color, odor, and sound; determine needed action.
  8. Perform engine manifold pressure tests (vacuum/boost); determine needed action.
  9. Perform cylinder power balance test; determine needed action.
  10. Perform cylinder cranking and running compression tests; determine needed action.
  11. Perform cylinder leakage test; determine needed action.
  12. Diagnose engine mechanical, electrical, electronic, fuel, and ignition concerns; determine needed action.

 

VIII. ENGINE PERFORMANCE

B. Computerized Controls

  1. Identify computerized control system components and configurations.
  2. Access and use service information to perform step-by-step (troubleshooting) diagnosis.
  3. Perform active tests of actuators using a scan tool; determine needed action.
  4. Describe the use of OBD monitors for repair and verification.
  5. Inspect and test computerized engine control system sensors, powertrain/engine control module (PCM/ECM), actuators, and circuits using a graphing multi-meter (GMM), digital storage oscilloscope (DSO), and/or scan tool; determine needed action.
  6. Describe the process for reprogramming or recalibrating the powertrain/engine control module (PCM/ECM)

C. Ignition System

  1. Identify ignition system components and configurations.
  2. Remove and replace spark plugs; inspect secondary ignition components for wear and damage; determine needed action.
  3. Diagnose ignition system related problems such as no-starting, hard starting, engine misfire, poor drive-ability, spark knock, power loss, poor mileage, and emissions concerns; determine needed action.
  4. Inspect and test crankshaft and camshaft position sensor(s); determine needed action.
  5. Inspect, test, and/or replace ignition control module and/or powertrain/engine control module; determine needed action.
