Canister Purge Solenoid: Testing and Inspection
Component Inspection
PURGE SOLENOID VALVE INSPECTION
Simulation Test
1. Carry out the "Purge Control Inspection".
-
If not as specified, perform the further inspection for the purge solenoid valve.
Airflow inspection
NOTE: Perform the following test only when directed.
1. Remove the purge solenoid valve.
2. Inspect airflow between the ports under the following conditions.
-
if as specified but the "Purge Control Inspection" is failed, inspect the vacuum hoses for improper routing, kinks or leakage, and inspect
"Circuit Open/Short Inspection".
-
If not as specified, replace the purge solenoid valve.
Circuit Open/Short Inspection
Open circuit
-
GND circuit (Purge solenoid valve connector terminal B and PCM connector terminal 3C through common connector)
-
Power circuit (Purge solenoid valve connector terminal A and main relay connector terminal D through common connector)
Short circuit
-
Purge solenoid valve connector terminal B and PCM connector terminal 3C to GND.
