Diagnostic Procedure
EBS00QJ6
1.
CHECK ECT SENSOR POWER SUPPLY CIRCUIT
1.
Turn ignition switch “OFF”.
2.
Disconnect engine coolant temperature (ECT) sensor harness
connector.
3.
Turn ignition switch “ON”.
4.
Check voltage between ECT sensor terminal 1 and ground with
CONSULT-II or tester.
OK or NG
OK
>> GO TO 2.
NG
>> Repair open circuit or short to ground or short to power
in harness or connectors.
2.
CHECK ECT SENSOR GROUND CIRCUIT FOR OPEN AND SHORT
1.
Turn ignition switch “OFF”.
2.
Check harness continuity between ECT sensor terminal 2 and engine ground.
Refer to Wiring Diagram.
3.
Also check harness for short to ground and short to power.
OK or NG
OK
>> GO TO 4.
NG
>> GO TO 3.
3.
DETECT MALFUNCTIONING PART
Check the following.
●
Harness for open or short between engine coolant temperature sensor and ECM
●
Harness for open or short between engine coolant temperature sensor and TCM (A/T models only)
>> Repair open circuit or short to ground or short to power in harness or connectors.
4.
CHECK ENGINE COOLANT TEMPERATURE SENSOR
Refer to
EC-192, "Component Inspection"
.
OK or NG
OK
>> GO TO 5.
NG
>> Replace engine coolant temperature sensor.

.
>> INSPECTION END
Component Inspection
EBS00QJ7
ENGINE COOLANT TEMPERATURE SENSOR
1.
Check resistance between engine coolant temperature sensor
terminals 1 and 2 as shown in the figure.
<Reference data>
*: These data are reference values and are measured between ECM terminal
72 (Engine coolant temperature sensor) and ground.
2.
If NG, replace engine coolant temperature sensor.

Component Description
EBS00QJ9
The heated oxygen sensor 1 is placed into the exhaust manifold. It
detects the amount of oxygen in the exhaust gas compared to the
outside air. The heated oxygen sensor 1 has a closed-end tube
made of ceramic zirconia. The zirconia generates voltage from
approximately 1V in richer conditions to 0V in leaner conditions. The
heated oxygen sensor 1 signal is sent to the ECM. The ECM adjusts
the injection pulse duration to achieve the ideal air-fuel ratio. The
ideal air-fuel ratio occurs near the radical change from 1V to 0V.
CONSULT-II Reference Value in Data Monitor Mode
EBS00QJA
Specification data are reference values.
On Board Diagnosis Logic
EBS00QJB
To judge the malfunction, the diagnosis checks that the heated oxy-
gen sensor 1 output is not inordinately high.
