SEF599K
Component DescriptionNLEC1627The EGR temperature sensor detects temperature changes in the
EGR passageway. When the EGR volume control valve opens, hot
exhaust gases flow, and the temperature in the passageway
changes. The EGR temperature sensor is a thermistor that modi-
fies a voltage signal sent from the ECM. This modified signal then
returns to the ECM as an input signal. As the temperature
increases, EGR temperature sensor resistance decreases. This
sensor is not used to control the engine system.
It is used only for the on board diagnosis.

*: These data are reference values and are measured between ECM terminal 72
(EGR temperature sensor) and ground.
When EGR system is operating.
Voltage: 0 - 1.5V
CAUTION:
Do not use ECM ground terminals when measuring input/
output voltage. Doing so may result in damage to the ECM's
transistor. Use a ground other than ECM terminals, such as
the ground.
On Board Diagnosis LogicNLEC1628
DTC No. Malfunction is detected when ... Check Items (Possible Cause)
P1401 A) An excessively low voltage from the EGR tempera-
ture sensor is sent to ECM even when engine cool-
ant temperature is low.+Harness or connectors
(The EGR temperature sensor circuit is shorted.)
+EGR temperature sensor
+Malfunction of EGR function
B) An excessively high voltage from the EGR tempera-
ture sensor is sent to ECM even when engine cool-
ant temperature is high.+Harness or connectors
(The EGR temperature sensor circuit is open.)
+EGR temperature sensor
+Malfunction of EGR function
DTC Confirmation ProcedureNLEC1629Perform ªPROCEDURE FOR MALFUNCTION Aº first. If 1st trip
DTC cannot be confirmed, perform ªPROCEDURE FOR MAL-
FUNCTION Bº.
NOTE:
If ªDTC Confirmation Procedureº has been previously conducted,
always turn ignition switch ªOFFº and wait at least 10 seconds
before conducting the next test.
