OBD-II Trouble Code Description for P0221 Skoda

Throttle/Pedal Position Sensor/Switch “B” Circuit Range/Performance

What does this mean?

OBD2 Code P0221 Skoda definition:
Electric Throttle Control Actuator consists of throttle control motor, throttle position (TP)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 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.

Symptoms

Causes

Possible causes of OBD code P0221 Skoda
– Harness or connector (The TP sensor 1 circuit is open or shorted.) – Electric throttle control actuator (TP sensor 1) may be faulty The Error code is generally activated on detection of the following conditions: An unexpected voltage from the TP sensor 1 is sent to ECM.
