Scheme 106

Note. If the reference pressure difference between the first and second checks is more than the specification, all the DTCs relating to the reference pressure (P043E, P043F, P2401, P2402 and P2419) will all be stored.

TEXT IN ILLUSTRATION

HINT

The canister pressure sensor, the leak detection pump and the vent valve are built into the canister pump module.

Scheme 108

TEXT IN ILLUSTRATION

Note. In the EVAP system of this vehicle, turning on the vent valve does not seal off the EVAP system. To check for leaks in the EVAP system, disconnect the air inlet vent hose and apply pressure from atmospheric side of the canister.

While the engine is running, if a predetermined condition (closed-loop, etc.) is met, the purge VSV is opened by the ECM and fuel vapors stored in the canister are purged to the intake manifold. The ECM changes the duty cycle ratio of the purge VSV to control purge flow volume.

The purge flow volume is also determined by the intake manifold pressure. Atmospheric pressure is allowed into the canister through the vent valve to ensure that the purge flow is maintained when negative pressure (vacuum) is applied to the canister.

The following two monitors run to confirm appropriate EVAP system operation.

Scheme 109

Scheme 110

Scheme 111

Scheme 112

1. Key-off monitor This monitor checks for EVAP (evaporative emission) system leaks and canister pump module malfunctions. The monitor starts 5 hours* after the power switch is turned off. At least 5 hours are required for the fuel to cool down to stabilize the EVAP pressure, thus making the EVAP system monitor more accurate. The leak detection pump creates negative pressure (vacuum) in the EVAP system and the pressure is measured. Finally, the ECM monitors for leaks from the EVAP system, and malfunctions in both the canister pump module and purge VSV based on the EVAP pressure. HINT: *: If the engine coolant temperature is not below 35°C (95°F) 5 hours after the power switch is turned off, the monitor check starts 2 hours later. If it is still not below 35°C (95°F) 7 hours after the power switch is turned off, the monitor check starts 2.5 hours later.
2. Purge flow monitor The purge flow monitor consists of the 2 monitors. The 1st monitor is conducted every time and the 2nd monitor is activated if necessary. The 1st monitor While the engine is running and the purge VSV (Vacuum Switching Valve) is on (open), the ECM monitors the purge flow by measuring the EVAP pressure change. If negative pressure is not created, the ECM begins the 2nd monitor. The 2nd monitor The vent valve is turned on (closed) and the EVAP pressure is then measured. If the variation in the pressure is less than 0.5 kPa(gauge) [3.75 mmHg(gauge)], the ECM interprets this as the purge VSV being stuck closed, and illuminates the MIL and stores DTC P0441 (2 trip detection logic). Atmospheric pressure check: In order to ensure reliable malfunction detection, the variation between the atmospheric pressures, before and after of the purge flow monitor, is measured by the ECM.

In order to discharge EVAP absorbed by canister to intake manifold, ECM opens purge VSV. EVAP discharge volume to intake manifold controlled by purge VSV duty cycle (current-carrying time). (Open: on, Close: off) Soak timer Built into ECM. To ensure accurate EVAP monitor, measures 5 hours (+/-15 min) after power switch is turned off. This allows fuel to cool down, stabilizing EVAP pressure. When approximately 5 hours elapsed, ECM activates ( see scheme 3(Scheme 112) ). Canister pump module Consists of (a) to (d) below. Canister pump module cannot be disassembled. (a) Vent valve Vents and closes EVAP system. When ECM turns valve on, EVAP system is closed. When ECM turns valve off, EVAP system is vented. Negative pressure (vacuum) is created in EVAP system to check for EVAP leaks by closing purge VSV, turning on vent valve (closing it) and operating leak detection pump ( see scheme 1(Scheme 108) ). (b) Canister pressure sensor Indicates pressure as voltages. ECM supplies regulated 5 V to pressure sensor, and uses feedback from sensor to monitor EVAP system pressure ( see scheme 2(Scheme 111) ). (c) Leak detection pump Creates negative pressure (vacuum) in EVAP system for leak check. (d) Reference orifice Has opening with 0.02 inch diameter. Vacuum is produced through orifice by closing purge VSV, turning off vent valve and operating leak detection pump, to monitor reference pressure. Reference pressure is used when checking for small EVAP leaks.

1. PERFORM ACTIVE TEST USING TECHSTREAM (OPERATE C/OPN RELAY) Connect the Techstream to the DLC3. Turn the power switch on (IG). Turn the Techstream on. Enter the following menus: Powertrain / Engine and ECT / Active Test / Control the Fuel Pump / Speed. Check whether the fuel pump operation sound occurs when performing the Active Test on the Techstream. OK Fuel pump operating sound occurs. NG --> See step 2 OK --> See step 9
2. INSPECT INTEGRATION RELAY (C/OPN RELAY) Inspect the integration relay. Refer to «INSPECTION»(ref-551525-S40824678752013051500000) . NG --> See step 10 OK: Go to next step
3. CHECK HARNESS AND CONNECTOR (C/OPN RELAY - ECM) Disconnect the ECM connector. Remove the integration relay from the engine room relay block. Disconnect the integration relay connector. Measure the resistance according to the value(s) in the table below. Standard Resistance (Check for Open) Tester Connection Condition Specified Condition 1B-7 - A57-8 (FC) Always Below 1 ohms NG --> REPAIR OR REPLACE HARNESS OR CONNECTOR OK: Go to next step
4. CHECK HARNESS AND CONNECTOR (C/OPN RELAY - IG2 RELAY) Remove the integration relay from the engine room relay block. Disconnect the integration relay connector. Measure the resistance according to the value(s) in the table below. Standard Resistance (Check for Open) Tester Connection Condition Specified Condition 1A-4 - 1B-6 Always Below 1 ohms NG --> REPAIR OR REPLACE HARNESS OR CONNECTOR OK: Go to next step
5. CHECK HARNESS AND CONNECTOR (C/OPN RELAY - FUEL PUMP) Disconnect the fuel pump connector. Remove the integration relay from the engine room relay block. Disconnect the integration relay connector. Measure the resistance according to the value(s) in the table below. Standard Resistance (Check for Open) Tester Connection Condition Specified Condition 1B-8 - R11-4 (B) Always Below 1 ohms Standard Resistance (Check for Short) Tester Connection Condition Specified Condition 1B-8 or R11-4 (B) - Body ground Always 10 kohms or higher NG --> REPAIR OR REPLACE HARNESS OR CONNECTOR OK: Go to next step
6. CHECK HARNESS AND CONNECTOR (FUEL PUMP - BODY GROUND) Disconnect the fuel pump connector. Measure the resistance according to the value(s) in the table below. Standard Resistance (Check for Open) Tester Connection Condition Specified Condition R11-5 (E) - Body ground Always Below 1 ohms NG --> REPAIR OR REPLACE HARNESS OR CONNECTOR OK: Go to next step
7. INSPECT FUEL PUMP Inspect the fuel pump. Refer to «INSPECTION»(ref-551530-S42605726372013051500000) . NG --> See step 11 OK: Go to next step
8. CHECK ECM POWER SOURCE CIRCUIT Check the ECM power source circuit. Refer to «ECM Power Source Circuit»(ref-551526-S33310737362013051500000) . NG --> REPAIR OR REPLACE ECM POWER SOURCE CIRCUIT OK --> See step 12
