DTC P1226 TP SENSOR
Component DescriptionINFOID:0000000006342113
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 LogicINFOID:0000000006342114
The MIL will not light up for this diagnosis.
DTC Confirmation ProcedureINFOID:0000000006342115
