TP Sensor For California

P1225 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 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.

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 and wait at least 10 seconds.
3.Turn ignition switch ON.
4.Check 1st trip DTC.
Is 1st trip DTC detected?
YES- Go to "Diagnosis Procedure".
NO- INSPECTION END


Diagnosis Procedure


1. CHECK ELECTRIC THROTTLE CONTROL ACTUATOR VISUALLY

1.Turn ignition switch OFF.
2.Remove the intake air duct. Service and Repair.





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, and then perform throttle valve closed position learning. [1][2][3][4][5][6][7]Component Tests and General Diagnostics, "THROTTLE VALVE CLOSED POSITION LEARNING : Special
Repair Requirement".

2. REPLACE ELECTRIC THROTTLE CONTROL ACTUATOR

Replace electric throttle control actuator. Service and Repair.
- INSPECTION END


Component Inspection


1. CHECK THROTTLE POSITION SENSOR

1.Turn ignition switch OFF.
2.Reconnect all harness connectors disconnected.
3.Perform Special Repair Requirement.
4.Turn ignition switch ON.
5.Set shift lever to D (CVT) or 1st (M/T) position.





6.Check the voltage between ECM harness connector and ground.





Is the inspection result normal?
YES- INSPECTION END
NO- GO TO 2.

2. REPLACE ELECTRIC THROTTLE CONTROL ACTUATOR

Replace electric throttle control actuator. Service and Repair.
- INSPECTION END
