Conditions for purging the adsorber (Renault Megane 2)

The control signal to the electromagnetic valve for purging the adsorber is supplied via contact C-E1 of the ECU connector under the following conditions:

• coolant temperature above 55°C;
• air temperature above 10°C;
• the engine is not in idle mode;
• the specified load threshold has been reached;
• the throttle position sensor is not in the idle position.

When performing diagnostics using the "on-board diagnostic system", purging the adsorber is not permitted.

The cyclic opening degree of the canister purge solenoid valve can be determined using the diagnostic tool by reading parameter PR102 (degree of cyclic opening of the solenoid valve of the absorber purge).

The solenoid valve is closed when the parameter value is below 1.2%.
