Located in the engine coolant passage of the cylinder, the
Engine Coolant Temperature Sensor (ECTS) is used to detect the engine
coolant temperature. The ECTS uses a thermistor whose resistance changes
with the temperature.
The electrical resistance of the ECTS decreases as the
temperature increases, and increases as the temperature decreases. The
reference +5V is supplied to the ECTS via a resistor in the ECM. That
is, the resistor in the ECM and the thermistor in the ECTS are connected
in series. When the resistance value of the thermistor in the ECTS
changes according to the engine coolant temperature, the output voltage
also changes.
During cold engine operation, the ECM increases the fuel
injection duration and controls the ignition timing using the
information of engine coolant temperature to avoid engine stalling and
improve drivability.
Good braking practices
Check to be sure the parking brake is not engaged and the parking brake
indicator light is out before driving away.
Driving through water may get the brakes wet. They can also get wet when
