Ford P0228 OBD-II Trouble Code Definition:

P0228 Throttle Pedal Position Sensor/Switch C Circuit High

P0228 Ford OBD-II Trouble CodeDescription:

OBD Trouble Code P0228
Throttle/Pedal Position Sensor/Switch “C” Circuit High
What does the code mean? OBD-ii Code P0228 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 Sumptoms of OBD code P0228
– Engine Light ON (or Service Engine Soon Warning Light) – No throttle response
Causes Causes of the OBD-II code P0228
– Harness or connector (The TP sensor circuit is open or shorted.) – Electric Throttle Control Actuator (or Throttle Body Motor) – Accelerator Pedal Position Sensor (APP) The Error code is generally activated on detection of the following conditions: An excessively high voltage from the Accelerator Pedal Position Sensor (APP) is sent to ECM.
