P0229 Throttle/Petal Position Sensor/Switch C Circuit Intermittent
P0229 OBD Code Description:

OBD2 Code P0229 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

Possible sumptoms of P0229
– Engine Light ON (or Service Engine Soon Warning Light) – No throttle response Possible Causes

Possible causes of P0229
– 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 Intermittent voltage from the TP sensor 1 is sent to ECM.
