Purge Valve
Purge Valve And Hoses Location
The purge valve is located at the rear of the engine on a bracket which is attached to the transmission bell housing. The purge valve is a solenoid
operated valve which is closed when de-energized. The purge valve is controlled by a 10 Hz PWM (pulse width modulation) signal from the ECM (
engine control module). When the engine operating conditions are correct, the ECM (engine control module) opens the purge valve which causes fuel
vapor and fresh air to be drawn through the charcoal cannister. The fresh air is drawn through the charcoal cannister via the DMTL pump fresh air vent.
