INSPECTION PROCEDURE
HINT:
Read freeze frame data usingthe hand−held tester.Freeze frame data records the engine conditions when
a malfunction is detected. When troubleshooting, freeze frame data can help determine if the vehicle was
running or stopped, if the engine was warmed up or not, if the air−fuel ratio was lean or rich, and other data
from the time the malfunction occurred.

1 CHECK HARNESS AND CONNECTOR(EGR VALVE POSITION SENSOR VOLTAGE)
(a) Disconnect the E18 EGR valve position sensor connec-
tor.
(b) Measure the voltage between the specified terminals of
the E18 EGR valve position sensor connector.
Standard:
Tester ConnectionSpecified Condition
VC (E18 −1) − E2 (E18 −2)4.5 to 5.5 V
(c) Reconnect the EGR valve position sensor connector.

1CHECK OTHER DTC OUTPUT(IN ADDITION TO P0400)
(a) Connect the hand−held tester to the DLC3.
(b) Turn the ignition switch to ON and turn the hand−held tester ON.
(c) Select the item ”DIAGNOSIS / OBD/MOBD / DTC INFO / CURRENT CODES”.
(d) Read DTCs.

INSPECTION PROCEDURE
HINT:
S After completing repairs, confirm that P0380 is not present again.
S Read freeze frame data using the hand −held tester. Freeze frame data records the engine conditions
when a malfunction is detected. When troubleshooting, freeze frame data can help determine if the
vehicle was running or stopped, if the engine was warmed up or not, if the air −fuel ratio was lean or
rich, and other data from the time the malfunction occurred.
1 CHECK OTHER DTC OUTPUT(IN ADDITION TO DTC P0380)
(a) Connect the hand −held tester to the DLC3.
(b) Turn the ignition switch to ON and turn the hand −held tester ON.
(c) Select the item ”DIAGNOSIS / OBD/MOBD / DTC INFO / CURRENT CODES”.
(d) Read DTCs.
Result:
