DTC P0217 ENGINE OVER TEMPERATURE

DTC P0217 ENGINE OVER TEMPERATUREPFP:21481
System DescriptionEBS01205
COOLING FAN CONTROL
*: These signals are sent to the ECM through CAN communication line.
The ECM controls the cooling fan corresponding to the vehicle speed, engine coolant temperature, air condi-
tioner ON signal. The control system has 3-step control [HIGH/LOW/OFF].
OPERATION
CONSULT-II Reference Value in Data Monitor ModeEBS01206
Specification data are reference values.
ECM Terminals and Reference ValueEBS01207
Specification data are reference values and are measured between each terminal and ground.
CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
age to the ECM's transistor. Use a ground other than ECM terminals, such as the ground.

DTC P0222, P0223 APP SENSOR

DTC P0222, P0223 APP SENSORPFP:18002
DescriptionEBS0120E
The accelerator pedal position sensor is installed on the upper end
of the accelerator pedal assembly. The sensors detect the accelera-
tor pedal position and sends a signal to the ECM. The ECM uses the
signal to determine the amount of fuel to be injected.
CONSULT-II Reference Value in Data Monitor ModeEBS0120F
Specification data are reference values.
*: These signals are converted by ECM internally. Thus, these differ from ECM terminals voltage.
ECM Terminals and Reference ValueEBS0120G
Specification data are reference values and are measured between each terminal and ground.
CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
age to the ECM's transistor. Use a ground other than ECM terminals, such as the ground.
