The OBD II mandated monitors have often been responsible for turning the check engine light on and sending the customer to your shop. Evaporative emission codes are common and repairing them can be difficult.  Often flow charts are dedicated to OEM test equipment.  Is there really a leak? Understanding how the system is designed to operate is crucial to efficient and accurate diagnosis and repair.  Monitoring how the evaporative emission system operates can be done in a number of ways.  Each of the three domestic manufacturers' uses more than one method to monitor the EVAP System. This course will teach system operation, scan tool diagnosis and pressure testing. Three different types of pressure and or smoke testing will be performed in class. A working model of a Ford EVAP system will be used in class to provide testing experience.

Note: This EVAP course will have additional testing displayed and performed in class.  Don't miss this opportunity to learn helpful information to fix your customer's car.
