6. DATA LIST
HINT:
Using the DATA LIST displayed by the hand±held tester, you can read the value of the switches, sensors,
actuators and so on without parts removal. Reading the DATA LIST as a first step of troubleshooting is one
of the method to shorten diagnostic time.
NOTICE:
The values given below for ºNormal Conditionº are representative values. A vehicle may still be nor-
mal even if the measured values are a little different from those listed here. Do not decide whether
a part is faulty or not solely according to the ºNormal Conditionº here.
(a) Warm up the engine.
(b) Turn the ignition switch OFF.
(c) Connect the Hand±held tester to the DLC3.
(d) Turn the ignition switch ON.
(e) Push the ºONº button of the hand±held tester.
(f) Select the item ºDIAGNOSIS / OBD/MOBD / DATA LIST / ALLº.
(g) According to the display on tester, read the ºDATA LISTº.

16INSPECT ENGINE COOLANT TEMPERATURE SENSOR
(a)Remove the engine coolant temperature sensor.
(b)Measure the resistance between the terminals. Resistance:
2.32 to 2.59 k at 20 C (68 F)
0.310 to 0.326 k at 80 C (176 F)
NOTICE:
In case of checking the engine coolant temperature sensor
in the water, be careful not to allow water to go into the ter-
minals. After checking, dry the sensor.
HINT:
Alternate procedure: Connect an ohmmeter to the installed en-
gine coolant temperature sensor and read the resistance. Use
an infrared thermometer to measure the engine temperature in
the immediate vicinity of the sensor. Compare these values to
the resistance/temperature graph. Change the engine temper-
ature (warm up or allow to cool down) and repeat the test.
