ON BOARD REFUELING VAPOR RECOVERY (ORVR)
DescriptionINFOID:0000000005398624
From the beginning of refueling, the air and vapor insi
de the fuel tank go through refueling EVAP vapor cut
valve and EVAP/ORVR line to the EVAP canister. The v apor is absorbed by the EVAP canister and the air is
released to the atmosphere.
When the refueling has reached the full level of the fuel tank, the refueling EVAP vapor cut valve is closed and
refueling is stopped because of auto shut-off. The vapor which was absorbed by the EVAP canister is purged
during driving.
WARNING:
When conducting inspectio ns below, be sure to observe the following:
• Put a “CAUTION: FLAMMABL E” sign in workshop.
• Do not smoke while servicing fuel system. Keep open flames and sparks away from work area.
• Be sure to furnish the workshop with a CO
2 fire extinguisher.
CAUTION:
• Before removing fuel line parts, carry out the following procedures:
- Put drained fuel in an explosion-proof containe r and put lid on securely.
- Release fuel pressure from fuel line. Refer to FL-5, "
Checking Fuel Line".
- Disconnect battery ground cable.
• Always replace O-ring when the fu el gauge retainer is removed.
• Do not kink or twist hose and tube when they are installed.
• Do not tighten hose and clamps excessively to avoid damaging hoses.
• After installation, run engine and check for fuel leaks at connection.
• Do not attempt to top off the fuel tank after the fuel pump nozzle shuts off automatically.
Continued refueling may cause fuel overflow, resulting in fuel spray and possibly a fire.
Component Function CheckINFOID:0000000005398625
1.CHECK ORVR FUNCTION
Check whether the following symptoms are present.
• Fuel odor from EVAP canister is strong.
• Cannot refuel/Fuel odor from the fuel filler opening is strong while refueling.
Is any symptom present?
YES >> Go to EC-443, "Diagnosis Procedure".
NO >> INSPECTION END
Diagnosis ProcedureINFOID:0000000005398626
1.INSPECTION START
Check whether the following symptoms are present.
A: Fuel odor from EVAP canister is strong.

POSITIVE CRANKCASE VENTILATION
DescriptionINFOID:0000000005398629
This system returns blow-by gas to the intake manifold.
The positive crankcase ventilation (PCV) valve is prov
ided to conduct crankcase blow-by gas to the intake
manifold.
During partial throttle operation of the engine, the intake manifold
sucks the blow-by gas through the PCV valve.
Normally, the capacity of the valve is sufficient to handle any blow-by
and a small amount of ventilating air.
The ventilating air is drawn from t he air inlet tubes into the crank-
case. In this process the air passes through the hose connecting air
inlet tubes to rocker cover.
Under full-throttle condition, the manifold vacuum is insufficient to
draw the blow-by flow through the valve. The flow goes through the
hose connection in the reverse direction.
On vehicles with an excessively high blow-by, the valve does not
meet the requirement. This is because some of the flow will go
through the hose connection to the air inlet tubes under all conditions.
Component InspectionINFOID:0000000005398630
1.CHECK PCV VALVE
With engine running at idle, remove PCV valve from rocker cover. A
properly working valve makes a hissing noise as air passes through
it. A strong vacuum should be felt immediately when a finger is
placed over valve inlet.
Is the inspection result normal?
YES >> INSPECTION END
NO >> Replace PCV valve.

REFRIGERANT PRESSURE SENSOR
REFRIGERANT PRESSURE SENSOR
DescriptionINFOID:0000000005398631
The refrigerant pressure sensor is installed at the condenser of the air conditioner system. The sensor uses an
electrostatic volume pressure transducer to convert refrigerant pressure to voltage. The voltage signal is sent
to ECM, and ECM controls cooling fan system.
Component Function CheckINFOID:0000000005398632
1.CHECK REFRIGERANT PRESSURE SENSOR OVERALL FUNCTION
1. Start engine and warm it up to normal operating temperature.
2. Turn A/C switch and blower fan switch ON.
3. Check the voltage between ECM harness connector and ground.
Is the inspection result normal?
YES >> INSPECTION END
NO >> Go to EC-451, "
Diagnosis Procedure".

VALUES ON THE DIAGNOSIS TOOL
Remarks:
• Specification data are reference values.
• Specification data are output/input values which are
detected or supplied by the ECM at the connector.
*Specification data may not be directly relat ed to their components signals/values/operations.
I.e. Adjust ignition timing with a timing light before m onitoring IGN TIMING, because the monitor may show the
specification data in spite of the ignition timing not bei ng adjusted to the specification data. this IGN TIMING
monitors the data calculated by the ECM according to the signals input from the camshaft position sensor and
other ignition timing related sensors.
