DTC P1225 TP SENSOR
Component Description INFOID:0000000004500287
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.
On Board Diagnosis Logic INFOID:0000000004500288
The MIL will not light up for this diagnosis.
DTC Confirmation Procedure INFOID:0000000004500289
NOTE:
If DTC Confirmation Procedure has been previously conduc ted, 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 10V at idle.
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.
5. If 1st trip DTC is detected, go to EC-1417, " Diagnosis Procedure " .
Diagnosis Procedure INFOID:00000000045002901.
CHECK ELECTRIC THROTTLE CONTROL ACTUATOR VISUALLY
1. Turn ignition switch OFF.
2. Remove the intake air duct.
3. Check if foreign matter is c aught between the throttle valve (1)
and the housing.
- : Vehicle front
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 EC-1084, " Throttle Valve Closed Position Learning " .
3. Perform EC-1084, " Idle Air Volume Learning " . PBIB0145E
