Pinpoint Tests
PINPOINT TEST A : EVAPORATIVE SYSTEM INCORRECT PURGE FLOW
TEST
CONDITIONS
DETAILS/RESULTS/ACTIONS
A1: CHECK FUEL FILLER CAP INSTALLATION AND CONDITION OF CANISTER, PIPES AND CONNECTORS
Make sure that the fuel filler cap is correctly installed and tightened.
Check the condition of the carbon canister.
Check the condition of all accessible pipes and connectors in the vapor line.
Are the canister and all pipes and connectors in good condition?
Yes
GO to A2
.
No
REPAIR as necessary. CLEAR the DTC, test the system for normal operation.
A2: CHECK THAT THE PURGE VALVE IS OPERATING
Disconnect the vapor pipe from the inlet port of the evaporative purge valve.
RUN the engine for 2 minutes, making sure that the engine reaches normal operating temperature.
Check that the evaporative purge valve is operating, by touch or by sound (using a stethoscope, it
will be possible to hear the valve operating).
Is the valve operating?
Yes
CHECK for related DTCs. Refer to the DTC Index above.
No
CHECK for purge valve related DTCs and refer to DTC Index.
