EVAPORATIVE EMISSION (EVAP)
CONTROL SYSTEM
INSPECTION
1. INSPECT LINES AND CONNECTIONS
Visually check for loose connections, sharp bends or damage.
2. INSPECT FUEL TANK
Visually check for deformation, cracks or fuel leakage.
3. INSPECT FUEL TANK CAP
Visually check if the cap and/or gasket are deformed or dam-
aged.
If necessary, repair or replace the cap.
4. INSPECT EVAP SYSTEM LINE
(a) Warm up the engine and stop the engine.
Allow the engine to warm up to normal operating tempera-
ture.
(b) Install a vacuum gauge (EVAP control system test equip-
ment vacuum gauge) to the EVAP service port on the
purge line.
(c) TOYOTA Hand-Held tester:
Forced driving of the VSV for the EVAP.
(1) Connect a TOYOTA hand-held tester to the DLC3.
(2) Start the engine.
(3) Push the TOYOTA hand-held tester main switch
ON.
(4) Use the ACTIVE TEST mode on the TOYOTA
hand-held tester to operate the VSV for the EVAP.
(d) If you have no TOYOTA Hand-Held Tester:
Forced driving of the VSV for the EVAP.
(1) Disconnect the VSV connector for the EVAP.
(2) Connect the positive (+) and negative (-) leads from
the battery to the VSV terminals for the EVAP.
(3) Start the engine.

CO/HC
INSPECTION
HINT:
This check is used only to determine whether or not the idle CO/
HC complies with regulations.
1. INITIAL CONDITIONS
(a) The engine is at normal operating temperature.
(b) Air cleaner is installed.
(c) All pipes and hoses of the air induction system are con-
nected.
(d) All accessories are switched OFF.
(e) All vacuum lines are properly connected.
HINT:
All vacuum hoses should be properly connected.
(f) SFI system wiring connectors are fully plugged.
(g) Ignition timing is set correctly.
(h) Transmission is in neutral range.
(i) Tachometer and CO/HC meter are calibrated by hand.
2. START ENGINE
3. RACE ENGINE AT 2,500 RPM FOR APPROX. 180
SECONDS
4. INSERT CO/HC METER TESTING PROBE AT LEAST
40 cm (1.3 ft) INTO TAILPIPE DURING IDLING
5. IMMEDIATELY CHECK CO/HC CONCENTRATION AT
IDLE AND/OR 2,500 RPM
HINT:
When performing the 2 mode (2,500 rpm and idle) test, follow
the measurement order prescribed by the applicable local regu-
lations.

[N]: Explains the system outline.
[O]: Indicates values or explains the function for reference during troubleshooting.
[P]: Indicates the reference page showing the position on the vehicle of the parts in the system circuit.
Example : Part ºL4º (Light Failure Sensor) is on page 36 of the manual.
*The letter in the code is from the first letter of the part, and the number indicates its order in parts
starting with that letter.
Example : L 4 Parts is 4th in order
Light Failure Sensor
[Q]: Indicates the reference page showing the position on the vehicle of Relay Block Connectors in the system circuit.
Example : Connector º1º is described on page 18 of this manual and is installed on the left side of the instrument
panel.
[R]: Indicates the reference page showing the position on the vehicle of J/B and Wire Harness in the system circuit.
Example : Connector º3Cº connects the Instrument Panel Wire and J/B No.3. It is described on page 22 of this
manual, and is installed on the instrument panel left side.
[S]: Indicates the reference page describing the wiring harness and wiring harness connector (the female wiring
harness is shown first, followed by the male wiring harness).
Example : Connector ºIE1º connects the floor wire (female) and Instrument panel wire (male). It is described on
page 42 of this manual, and is installed on the left side kick panel.
[T]: Indicates the reference page showing the position of the ground points on the vehicle.
Example : Ground point ºBOº is described on page 50 of this manual and is installed on the back panel center.

The ºCurrent Flow Chartº section, describes which parts each power source (fuses, fusible links, and circuit breakers)
transmits current to. In the Power Source circuit diagram, the conditions when battery power is supplied to each system
are explained. Since all System Circuit diagrams start from the power source, the power source system must be fully
understood.
