- Start the engine.
- Disconnect the vacuum hose between the purge solenoid valve and the charcoal canister.
- Put a finger to the purge solenoid valve and verify that there is no vacuum applied when the engine is cold.
- If there is a vacuum, inspect the following:
- Wiring harness and connectors (Purge solenoid valve terminal B-PCM terminal 2S)
- Purge solenoid valve (stuck open) (See PURGE SOLENOID VALVE INSPECTION ).
- If there is a vacuum, inspect the following:
- Warm up the engine to the normal operating temperature.
- Stop the engine.
- Connect the M-MDS to the DLC-2 and verify that the DTC P0443:00 is shown. Perform the DTC inspection. (See DTC P0443:00 [MZR 1.5] ).
- Switch the ignition to ON.
- Access the ECT1 PID. (See ON-BOARD DIAGNOSTIC TEST [MZR 1.5] ).
- Verify that the engine coolant temperature is more than 60 °C {140 CF}
.
- If the M-MDS indicates less than 60 °C {140 °F} , perform the ECT sensor No.1 inspection. (See ENGINE COOLANT TEMPERATURE (ECT) SENSOR INSPECTION ).
- Put a finger to the purge solenoid valve and verify that there is vacuum applied with engine at idle and warmed up.
