Canister Purge Solenoid: Testing and Inspection
EVAP Purge Solenoid Testing and Inspection
NOTE:
Use only fuel resistant hoses when servicing evaporative emission control system.
PROCEDURE
1.
Disconnect Solenoid electrical connector, and apply vacuum. Using two jumper wires, energize the solenoid by connecting one of the solenoid
terminals to ground, and the other terminal to battery positive.
^
A "click" should be heard as voltage is applied to terminal.
^
Vacuum should hold when voltage is applied, and bleed off when disconnected.
2.
Disconnect jumper wires.
3.
Measure resistance between Purge Solenoid terminals.
^
Resistance should be between 36 and 44 ohms.
4.
If solenoid failed any test, replace solenoid. See COMPONENT REPLACEMENT AND REPAIR PROCEDURES.
