CANISTER PURGING VALVE CIRCUIT
1.DEF : Open circuit or short-circuit
CO : Open circuit
CC.O : Shot circuit at mass
CC.1 : Short circuit at + 12 V.
RECOMMENDATIONS
Conditions for diagnostic application for memorized failure:
Set the contact on or launch commend “AC016: Canister Purging Valve”
In case of failures addition, treat a s most important failure “DF009 actuators
relay control circuit
”.
* If the failure is memorized with OBD indicator on, check in the context part,

ndicator
lighting request is affirmative. In this case, proceed as per bellow mentioned
method.
Check the connection and the connector state of the canister purging valve .

Replace the canister purging valve if is necessary.
Check with the contact on, the presence
of +12 Volts at pin 1 of the purging valve
.
Fix if necessary.
Connect the 90 ways terminal box instead of the injection computer then check the
insulation and
the continuity of the line:
Pin 4 injection computer > pin 2 canister purging valve
Fix if necessary
Replace the canister purging valve if necessary.
If the problem is persisting after these checking, fix the other failures then perform the conformity
checking.
