Canister Purge Solenoid: Testing and Inspection
Evaporative (EVAP) Emissions Canister Purge Valve Check
Circuit Description
Canister purge is controlled by a solenoid valve that allows manifold vacuum to purge the canister. The powertrain control module (PCM) supplies a
ground to energize the solenoid valve (purge "ON"). The EVAP purge solenoid control is turned "ON" and "OFF" several times a second. The duty
cycle (pulse width or "ON" time) is determined by engine operating conditions including load, throttle position, coolant temperature and ambient
temperature. The duty cycle is calculated by the PCM and the purge solenoid is enabled when the appropriate conditions have been met:
-
The engine run time after start is more than 60 seconds.
-
The engine coolant temperature is above 30 °C (86 °F).
-
The fuel control system is operating in the closed-loop mode.
Diagnostic Aids
-
Make a visual check of vacuum hoses.
-
Check the throttle body for possible cracked.
-
Check the malfunction indicator lamp for a possible mechanical problem.
