TROUBLE DIAGNOSIS Ð General Description
Symptom Matrix Chart (Cont'd)
EC-49
Charge Air Temperature Sensor
The charge air temperature sensor is used to detect the charge air
temperature. The sensor modi®es a voltage signal from the ECM.
The modi®ed signal returns to the ECM as the charge air tempera-
ture input. The sensor uses a thermistor which is sensitive to the
change in temperature. The electrical resistance of the thermistor
decreases as temperature increases.
The ECM uses this signal for the charge air cooler control.

*1: When nothing is displayed or the meaningless symbol is displayed in the ``Self-diag result'' mode with CONSULT, perform ``Diagnostic Test Mode II
(Self-diagnostic results)'' with ECM. Refer to EC-32.
DIAGNOSTIC TROUBLE CODE CONFIRMATION
PROCEDURE
1) Turn ignition switch ``ON'' and wait at least 5 seconds.
2) Turn ignition switch ``OFF'', wait at least 5 seconds and then turn ``ON''.
3) Perform ``Diagnostic Test Mode II (Self-diagnostic results)'' with ECM.
