Code P0223 2002 Toyota Corolla Description
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 Engine Control Module (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.
What are the Possible Causes of the DTC P0223 2002 Toyota Corolla?
- Faulty Throttle position sensor
- Throttle position sensor harness is open or shorted
- Throttle position sensor poor electrical connection
