July 1: So it begins. Don't worry, this is not in the correct legal jurisdiction!

Inspection Procedure

  1. Turn ignition off. Remove the EVAP canister purge solenoid. See EVAP CANISTER PURGE SOLENOID  . Lightly tap the EVAP canister purge solenoid on a hard surface.
  2. Inspect for carbon particles exiting either of the vacuum ports. If no carbon particles were detected, but a blockage was detected during a diagnostic procedure, install the original EVAP canister purge valve. Continue with the cleaning procedure.
  3. If carbon particles are found during the inspection procedure, continue with the cleaning procedure. If a diagnostic procedure directed you to replace the EVAP canister purge valve and no carbon particles were detected, replace the EVAP canister purge valve. Return to the diagnostic procedure that sent you here.
