DTC P1225 TP SENSOR





Component Description





Electric throttle control actuator consists of throttle control motor, throttle position sensor, etc. The throttle position sensor responds to the throttle valve movement.
The throttle position sensor has two sensors. These sensors are a kind of potentiometers which transform the throttle valve position into output voltage, and emit the voltage signal to the ECM. In addition, these sensors detect the opening and closing speed of the throttle valve and feed the voltage signals to the ECM. The ECM judges the current opening angle of the throttle valve from these signals and the
ECM controls the throttle control motor to make the throttle valve opening angle properly in response to driving condition.

The MIL will not light up for this self-diagnosis.









DTC Confirmation Procedure

NOTE:
If DTC Confirmation Procedure has been previously conducted, always turn ignition switch OFF and wait at least 10 seconds before conducting the next test.
TESTING CONDITION:
Before performing the following procedure, confirm that battery voltage is more than 10 V at idle.
1. Turn ignition switch OFF and wait at least 10 seconds.
2. Turn ignition switch ON.
3. Check 1st trip DTC.
4. If 1st trip DTC is detected, go to For California.




Diagnosis Procedure
1.CHECK ELECTRIC THROTTLE CONTROL ACTUATOR VISUALLY
1. Turn ignition switch OFF.
2. Remove the intake air duct.





3. Check if foreign matter is caught between the throttle valve (1) and the housing.
Arrow Indicates Vehicle front
- Illustration shows the view with intake air duct removed.
OK or NG
OK - GO TO 2.
NG - Remove the foreign matter and clean the electric throttle control actuator inside.
2.REPLACE ELECTRIC THROTTLE CONTROL ACTUATOR
1. Replace the electric throttle control actuator.
2. Perform For California.
3. Perform For California.
