Circuit Description
The ECT sensor uses a thermistor to control the signal voltage to the ECM. The ECM supplies a voltage on the signal
circuit to the sensor. When the engine coolant is cold, the resistance is high; therefore the ECT signal voltage will be high.
Engine Coolant Temperature Sensor Inspection
1. Turn the ignition switch to “ON” position.
2. Measure the voltage between the ECM pin No. 78 and No. 79.

3. Turn the ignition switch to “OFF” position.
4. Disconnect the ECT sensor connector.
5. Turn the ignition switch to “ON” position.
6. Measure the resistance between the ECT sensor terminal pin No. 1 and No. 4.

ACCELERATOR PEDAL MODULE
The Acceleration Pedal Position (APP) sensor is mounted on the accelerator pedal assembly. The sensor is actually
two individual APP sensors and one housing. This sensor works with the Throttle Position (TP) sensor to provide input
to the Engine Control Module (ECM) regarding driver requested accelerator pedal and throttle angle at the throttle body.
When the APP Sensor is Defected
When the APP1 or APP 2 sensor is defected condition, the engine is still running at idle condition but, the accelerator
pedal reaction is not response correctly and also, the engine rpm will be reacted to 4,000 rpm slowly. If the APP 1
sensor is out of order, the APP 2 sensor will be conducted with signal as a default signal but, the throttle valve opening
is limited 60% and delayed opening speed.
When the TP Sensor or Servo Motor is Defected
When the TP 1, 2 sensor or servo motor is defected condition, the throttle valve will be closed to the spring capsule by
spring force, at this condition, the throttle valve will open 10° ~ 20°and engine rpm will be controlled by ECM with opening
(ON/OFF) time of injector. The engine rpm will be maintaining 900 rpm (at idle) to 1,800 according to the engine load.
