DTC P1225 TP SENSOR
PFP:16119
Component Description
EBS00MK4
Electric throttle control actuator consists of throttle control motor,
acceleration pedal position sensor, throttle position sensor, etc. The
throttle position sensor responds to the throttle valve movement.
The throttle position sensor has the 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 addi-
tion, 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 sig-
nals and the ECM controls the throttle control motor to make the
throttle valve opening angle properly in response to driving condi-
tion.
On Board Diagnosis Logic
EBS00MK5
The MIL will not light up for this diagnosis.
DTC Confirmation Procedure
EBS00MK6
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 10V at idle.
WITH CONSULT-II
1.
Turn ignition switch “ON”.
2.
Select “DATA MONITOR” mode with CONSULT-II.
3.
Turn ignition switch “OFF” and wait at least 10 seconds.
4.
Turn ignition switch “ON”.
5.
If 1st trip DTC is detected, go to
EC-522, "Diagnostic Procedure"
.
WITH GST
Follow the procedure “WITH CONSULT-II” above.
