(2) Turn the ignition switch to ON.
(3) Select the “ PID/DATA MONITOR AND
RECORD” function on the NGS tester display
and press TRIGGER.
(4) Select “ ECT V” on the NGS tester display and
press START. The NGS tester measures and
shows the voltage.

Inspection of Resistance
1. Remove the engine coolant temperature sensor.
2. Place the engine coolant temperature sensor in
water with a thermometer, and heat the water
gradually.
3. Measure the resistance of the sensor by using an
ohmmeter.
