10) Maintain the following conditions for at least 5 consecutive
seconds.
ENG SPEED 2,000 - 2,800 rpm
VHCL SPEED SE 10 km/h (6 MPH) or more

THRTL POS SEN (X + 0.23) − (X + 0.74) V
X = Voltage value measured at step 7
Selector lever Suitable position
11) If 1st trip DTC is detected, go to “Diagnostic Procedure”,

Overall Function Check
NGEC0345
Use this procedure to check the overall function of the EGR tem-
perature sensor. During this check, a 1st trip DTC might not be
confirmed.
PROCEDURE FOR MALFUNCTION B
NGEC0345S01
Without CONSULT-II
1) Start engine and warm it up to normal operating temperature.
2) Run engine at idle for at least 2 minutes.
3) Confirm that EGR valve is not lifting. If NG, perform trouble
diagnosis for DTC P1402. Refer to EC-466.
4) Check voltage between ECM terminal 63 (EGR temperature
sensor signal) and ground at about 1,500 rpm with EGR valve
lifted up to the full position by hand.
Voltage should decrease to less than 1.0V.
5) If NG, go to “Diagnostic Procedure”, EC-463.
If OK, perform trouble diagnoses for DTC P0400 and P1400.
Refer to EC-327, 452.
