CIRCUIT DESCRIPTION
This circuit sends a signal to the ECU that DTC output is required.
WIRING DIAGRAM
INSPECTION PROCEDURE
1 Check voltage between terminals Tc and E1 of DLC1.
CHECK:
(a) Turn ignition switch ON.
(b) Measure voltage between terminals Tc and E1 of DLC1.
OK:
Voltage: 10 − 16 V
NG Proceed to next circuit inspection shown on
matrix chart (See page DI−336).
OK

Actuator Control Cable Inspection
CHECK:
(a) Check that the actuator, control cable and throttle link are properly installed and that the cable and link
are connected correctly.
(b) Check that the actuator and bell crank are operating smoothly.
(c) Check that the cable is not loose or too tight.
HINT:
If the control cable is very loose, the vehicle’s loss of speed going uphill will be large.
If the control cable is too tight, the idle RPM will become high.

1996 RAV4 (RM447U)
EMISSION CONTROL SYSTEM
PURPOSE
The emission control systems are installed to reduce the amount of HC, CO and NOx exhausted from the
engine ((3), (4) and (5)), to prevent the atmospheric release of blow−by gas−containing HC (1) and evapo-
rated fuel containing HC being released from the fuel tank (2).
The function of each system is shown in the following table.
SystemAbbreviationFunction
(1) Positive Crankcase Ventilation
(2) Evaporative Emission Control
(3) Exhaust Gas Recirculation
(4) Three−Way Catalytic Converter
(5) Sequential Multiport Fuel Injection*PCV

INSPECTION
1. REMOVE PCV VALVE
2. INSTALL CLEAN HOSE TO PCV VALVE
3. INSPECT PCV VALVE OPERATION
(a) Blow into the cylinder head side, and check that air
passes through easily.
CAUTION:
Do not suck air through the valve. Petroleum substances
inside the valve are harmful.
(b) Blow air into the intake manifold side, and check that air
passes through with difficulty.
If operation is not as specified, replace the PCV valve.
4. REMOVE CLEAN HOSE FROM PCV VALVE
5. REINSTALL PCV VALVE
6. VISUALLY INSPECT HOSES, CONNECTIONS AND
GASKETS
Check for cracks, leaks or damage.

INSPECTION
1. VISUALLY INSPECT LINES AND CONNECTIONS
Look for loose connections, sharp bends or damage.
2. VISUALLY INSPECT FUEL TANK
Look for deformation, cracks or fuel leakage.
3. VISUALLY INSPECT FUEL TANK CAP
Check if the cap and/or gasket are deformed or damaged.
If necessary, repair or replace the cap.
4. DISCONNECT EVAP HOSES FROM CHARCOAL CAN-
ISTER
5. VISUALLY INSPECT CHARCOAL CANISTER
Look for cracks or damage.
6. CHECK FOR CLOGGED FILTER, AND STUCK CHECK
VALVE AND DIAPHRAGM
(a) Install a plug to port E.
(b) While holding port B closed, blow air (1.76 kPa, 18
gf/cm
2, 0.26 psi) into port A and check that air flows from
port D.
(c) While holding port B and port D closed, blow air (1.76 kPa,
18 gf/cm
2, 0.26 psi) into port A and check that air does not
flow from port C.

(d) Apply vacuum (3.43 kPa, 26 mmHg, 1.01 in.Hg) to port B,
check that the vacuum does not decrease when port C is
closed, and check that the vacuum decreases when port
C is released.
(e) While holding port C closed, apply vacuum (1.23 kPa, 9.2
mmHg, 0.36 in.Hg) to port A and check that air flows into
port B.
If a problem is found, replace the charcoal canister.
(f) Remove the plug.
7. RECONNECT EVAP HOSES
8. INSPECT VSV FOR EVAP (See page SF−45)
9. INSPECT VSV FOR VAPOR PRESSURE SENSOR (See
page SF−47)
10. INSPECT VAPOR PRESSURE SENSOR (See page
