Turn the ignition switch ON.
Check the MIL blinks.
Is the MIL blinking?
NO - Loose or poor contact on the ECT sen-
sor connector.
YES - GO TO STEP 2.
2. ECT Sensor Resistance Inspection
Turn the ignition switch OFF.
Disconnect the ECT sensor connector.
Measure the resistance at the ECT sensor termi-
nals.
Connection: Yellow/blue(+)- Green/orange (-)
(sensor side terminals)
Standard: 2.3 - 2.6
n
(20 °C/68 °F)
Is the resistance within 2.3-2.6
n
(20 ° C/68 ° F)?
NO - Faulty ECT sensor.
YES - GO TO STEP 3.
3. ECT Sensor Power Input Line Voltage Inspection
Turn the ignition switch ON.
Measure the voltage between the ECT sensor
connector terminal of the wire harness side and
ground.

Is the voltage within 4. 75 - 5.25 V?
No - • Open or short circuit in Yellow/blue
wire.
• Loose or poor contact on the ECM
connectors.
YES - GO TO STEP 4.
4. ECT Sensor Signal Line Voltage Inspection
Measure the voltage at t he ECT sensor connec-
tor of the wire harness side.
Connection: Yellow/blue(+)- Green/orange(-)
Standard: 4.75- 5.25 V
Is the voltage within 4. 75 - 5.25 V?
No - • Open or short circuit in Green/
orange wire.
