HD24 - Check Canister Purge Solenoid (CANP)
This Pinpoint Test Step will verify the mechanical integrity of the Canister Purge Solenoid (CANP). The solenoid and circuit have been checked electrically and reported during KOEO Self-Test.
- Key Off.
- Disconnect CANP solenoid.
- Connect 12 volt DC power source to solenoid. CAUTION must be observed for proper pin orientation. Refer to the vehicle electrical block diagram. Electrical Diagrams
- Connect positive power source to VPWR circuit and negative lead to CANP circuit at the CANP solenoid harness connector.
- Apply 53 kPa (16 inHg) of vacuum to the manifold side of the CANP solenoid. Apply power source.
- Does the solenoid open and pass air freely?
YES -- Evaporative System is functioning properly. GO to HD25 for Base Engine concerns. HD25 - Check For Base Engine Concerns
NO -- REPLACE Canister Purge solenoid. Rerun quick test. Diagnostic Subroutines (DSR) - Extracting Codes
