OBD II engine management systems are required to monitor evaporative (Evap) Emissions. These systems are utilized in all 1995 and newer OBD II vehicles. OBD II mandates that the PCM not only monitors the Evap system, but also performs self test diagnostics which in some models have an air pump to pressurize the entire system including the fuel tank.
The student will be able to diagnose and repair these systems upon completion of this course.
