PREPARATION:
(a) Remove the glove compartment (See page SF±73).
(b) Turn the ignition switch ON.
CHECK:
Check VSV function.
(1) Connect between terminal EVA1 of the ECM
connector and body ground (ON).
(2) Disconnect between terminal EVP of the ECM con-
nector and body ground (OFF).
OK:
(1) VSV is ON:
Air from pipe E is flowing out through pipe F.
(2) VSV is OFF:
Air does not flow from pipe E to pipe F.
OK Go to step 9.

INSPECTION PROCEDURE
HINT:

If DTCs ºP0110º (Intake Air Temp. Circuit Malfunction), ºP0115º (Engine Coolant Temp. Circuit Mal-
function), ºP0120º (Throttle/Pedal Position/Switch ºAº Circuit Malfunction), ºP1410º (EGR Valve Posi-
tion Sensor Circuit Malfunction) are output simultaneously, E2 (Sensor Ground) may be open.

Read freeze frame data using TOYOTA hand±held tester or OBD II scan tool. Because freeze frame
records the engine conditions when the malfunction is detected, when troubleshooting it is useful for
determining whether the vehicle was running or stopped, the engine warmed up or not, the air±fuel
ratio lean or rich, etc. at the time of the malfunction.
1 Check voltage between terminal VC of wire harness side connector and body
ground.
PREPARATION:
(a) Disconnect the vacuum hose from EGR valve.
(b) Disconnect the EGR valve position sensor connector.
(c) Turn the ignition switch ON.
CHECK:
Measure voltage between terminal 1 of wire harness side con-
nector and body ground.
OK:
Voltage: 4.5 ~ 5.5 V
NG Go to step 4.
OK
2 Check EGR valve position sensor.
PREPARATION:
Disconnect the EGR valve position sensor connector.
CHECK:
Measure resistance between terminals 1 (VC) and 2 (E2) of
EGR valve position sensor.
OK:
Resistance: 1.5 ~ 4.3 kW
NG Replace EGR valve position sensor.
OK
