Note. The Evaporative System Check (Automatic Mode) consists of 5 steps performed automatically by the Techstream. It takes a maximum of approximately 18 minutes. Do not perform the Evaporative System Check when the fuel tank is more than 90% full because the cut-off valve may be closed, making the fuel tank leak check unavailable. Do not run the engine during this operation. When the temperature of the fuel is 35°C (95°F) or more, a large amount of vapor forms and any check results become inaccurate. When performing the Evaporative System Check, keep the fuel temperature below 35°C (95°F).

When either of these DTCs, as well as other DTCs relating to electronic throttle control system malfunctions is stored, the hybrid vehicle control ECU enters fail-safe mode. During fail-safe mode, the hybrid vehicle control ECU cuts the current to the throttle actuator, and the throttle valve is returned to a 6.5° throttle angle by the return spring. The hybrid vehicle control ECU stops the engine and the vehicle can be driven using solely the hybrid system. If the accelerator pedal is depressed firmly and gently, the vehicle can be driven slowly.

RELATED DTCS

If any EVAP system DTCs are set, the malfunctioning area can be determined using the table below.

Scheme 114

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

Scheme 115

TEXT IN ILLUSTRATION

HINT

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

Scheme 116

TEXT IN ILLUSTRATION

Note. In this vehicle's EVAP system, 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 the 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 hybrid vehicle control ECU and stored fuel vapors in the canister are purged into the intake manifold.

The purge flow volume is affected by the intake manifold pressure (vacuum). To control the purge volume, the hybrid vehicle control ECU changes the duty cycle ratio of the purge VSV based on the pressure (vacuum) in the intake manifold. The hybrid vehicle control ECU uses values received from the manifold absolute pressure sensor to monitor the pressure (vacuum) in the intake manifold.

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 the appropriate EVAP system operation.

Scheme 117

Scheme 118

Scheme 119

Scheme 120

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 hybrid vehicle control ECU 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 hybrid vehicle control ECU monitors the purge flow by measuring the EVAP pressure change. If negative pressure is not created, the hybrid vehicle control ECU begins the 2nd monitor. The 2nd monitor The vent valve is turned off (open) and the EVAP pressure is measured. If the variation in the pressure is less than 0.5 kPa-g (3.75 mmHg-g), the hybrid vehicle control ECU interprets this as the purge VSV being stuck closed, and illuminates the MIL and sets 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 the purge flow monitor, is measured by the hybrid vehicle control ECU. TEXT IN ILLUSTRATION *1 EVAP Purge Flow *2 to Intake Manifold *3 Hybrid Vehicle Control ECU *4 Soak Timer *5 Purge VSV (on) *6 Fuel Cap *7 Canister Filter *8 Fuel Tank *9 Leak Detection Pump (off) *10 Canister Pressure Sensor *11 Reference Orifice (0.02 inch) *12 Vent Valve (off) *13 Canister Pump Module *14 Canister Component Operation Canister Contains activated charcoal to absorb EVAP (evaporative emissions) generated in fuel tank. Cut-off valve Located in fuel tank. Valve floats and closes when fuel tank is 100% full. Purge VSV (Vacuum Switching Valve) Opens or closes line between canister and intake manifold. The hybrid vehicle control ECU uses purge VSV to control EVAP purge flow. In order to discharge EVAP absorbed by canister to intake manifold, hybrid vehicle control ECU opens purge VSV. EVAP discharge volume to intake manifold is controlled by purge VSV duty cycle (current-carrying time) (Open: on; Closed: off). Manifold absolute pressure sensor Measures the pressure (vacuum) of the intake manifold. The hybrid vehicle control ECU changes the duty cycle ratio of the purge VSV based on measured values to control the purge flow volume. Soak timer Built into hybrid vehicle control ECU. To ensure accurate EVAP monitor, it 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, hybrid vehicle control ECU activates (Scheme 81) Canister pump module Consists of (a) to (d) below. Canister pump module cannot be disassembled. (a) Vent valve Vents and closes EVAP system. When hybrid vehicle control ECU turns valve on, EVAP system is closed. When hybrid vehicle control ECU 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 (b) Canister pressure sensor Indicates pressure as voltage. Hybrid vehicle control ECU supplies regulated 5 V to canister pressure sensor, and uses feedback from sensor to monitor EVAP system pressure see scheme 2 (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 indicates small leak of EVAP.

Reconnect the integration relay connector. Reinstall the integration relay. 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 L13-5 - Body ground Always Below 1 ohms Reconnect the fuel pump connector. NG --> REPAIR OR REPLACE HARNESS OR CONNECTOR OK: Go to next step
7. INSPECT FUEL PUMP Inspect the fuel pump assembly. Refer to «INSPECTION»(ref-398229-S12513094102011051600000) . NG --> See step 11 OK: Go to next step
8. CHECK HARNESS AND CONNECTOR (EFI MAIN RELAY - IGCT RELAY) Remove the integration relay from the engine room relay block. Disconnect the integration relay connector. Remove the IGCT relay from the engine room relay block. Measure the resistance according to the value(s) in the table below. Standard Resistance (Check for Open) Tester Connection Condition Specified Condition 1B-2 - IGCT relay terminal 5 Always Below 1 ohms Standard Resistance (Check for Short) Tester Connection Condition Specified Condition 1B-2 or IGCT relay terminal 5 - Body ground Always 10 kohms or higher Reconnect the integration relay connector. Reinstall the relay. NG --> REPAIR OR REPLACE HARNESS OR CONNECTOR OK --> See step 12
