P1226 TP SENSOR





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 potentiometer which transform the throttle valve position into output voltage, and emit the voltage signals to the ECM. The ECM judges the current opening angle of the throttle valve from these signals and controls the throttle valve opening angle in response to driving conditions via the throttle control motor.

DTC CONFIRMATION PROCEDURE
1.PRECONDITIONING
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.
- GO TO 2.
2.PERFORM DTC CONFIRMATION PROCEDURE
1. Turn ignition switch ON.
2. Turn ignition switch OFF, wait at least 10 seconds.
3. Turn ignition switch ON.
4. Repeat steps 2 and 3 for 32 times.
5. Check 1st trip DTC.
Is 1st trip DTC detected?
YES - Go to For Mexico.
NO - INSPECTION END




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.

Is the inspection result normal?
YES - GO TO 2.
NO - Remove the foreign matter and clean the electric throttle control actuator inside.
2.REPLACE ELECTRIC THROTTLE CONTROL ACTUATOR
1. Replace electric throttle control actuator.
2. Go to For Mexico.
- INSPECTION END




Special Repair Requirement
1.PERFORM THROTTLE VALVE CLOSED POSITION LEARNING
For Mexico
- GO TO 2.
2.PERFORM IDLE AIR VOLUME LEARNING
For Mexico
- END
