    Connector Terminal
    F16 2 Ground Battery voltage

Is the inspection result normal?

YES>>

GO TO 3.

NO>>

GO TO 2.

CHECK EVAP CANISTER PURGE VOLUME CONTROL SOLENOID VALVE POWER SUPPLY CIRCUIT

  1. Turn ignition switch OFF.

  2. Disconnect IPDM E/R harness connector.

  3. Check the continuity between EVAP canister purge volume control solenoid valve harness connector and IPDM E/R harness connector.

    + Continuity

    F16 2 F35 73 Existed
  4. Also check harness for short to ground.

Is the inspection result normal?

YES>>

Perform the trouble diagnosis for power supply circuit.

NO>>

Repair or replace error-detected parts.

CHECK EVAP CANISTER PURGE VOLUME CONTROL SOLENOID VALVE GROUND CIRCUIT

  1. Turn ignition switch OFF.

  2. Disconnect ECM harness connector.

  3. Check the continuity between EVAP canister purge volume control solenoid valve harness connector and ECM harness connector.

    + Continuity

    Connector Terminal Connector Terminal
    F16 1 F71 126 Existed
  4. Also check harness for short to power.

Is the inspection result normal?

YES-1>>

With CONSULT: GO TO 4.

YES-2>>

Without CONSULT: GO TO 5.

NO>>

Repair or replace error-detected parts.

CHECK EVAP CANISTER PURGE VOLUME CONTROL SOLENOID VALVE OPERATION

With CONSULT

  1. Reconnect all harness connectors disconnected.

  2. Start engine.

  3. Perform “PURG VOL CONT/V” in “ACTIVE TEST” mode of “ENGINE” using CONSULT.

  4. Check that engine speed varies according to the valve opening.

Does engine speed vary according to the valve opening?

YES>>

Check intermittent incident. Refer to Intermittent Incident.

NO>>

GO TO 5.

CHECK EVAP CANISTER PURGE VOLUME CONTROL SOLENOID VALVE

Check the EVAP canister purge volume control solenoid valve. Refer to Component Inspection.

Is the inspection result normal?

YES>>

Check intermittent incident. Refer to Intermittent Incident.

NO>>

Replace EVAP canister purge volume control solenoid valve. Refer to Exploded View.
