Details of the Hyundai p0221 OBD Code
Hyundai fault code P0221 relates to an issue with the throttle/pedal position sensor B circuit.
OBD code P0221 for Hyundai vehicles indicates an issue with the Throttle/Pedal Position Sensor/Switch B Circuit Range/Performance.
This code is triggered by the Engine Control Module (ECM) when it detects that the voltage signal from the throttle position sensor or pedal position sensor is outside the expected range or not performing as it should.
This sensor is crucial for the ECM to determine the driver’s desired throttle position and adjust engine performance accordingly.
If this sensor malfunctions, it can lead to drivability issues and poor engine performance.
Mechanic’s Tech Notes
Detailed information on Hyundai fault code P0221, including symptoms, causes, and diagnostic steps for resolution.
To diagnose and fix OBDII code P0221 in a Hyundai, start by checking the throttle position sensor (TPS) circuit.
Use a voltmeter to test the TPS sensor’s voltage signal.
Ensure the TPS is functioning correctly by checking for smooth voltage changes as the throttle is opened and closed.
Inspect the wiring harness and connectors for any damage, corrosion, or loose connections.
Verify the TPS signal using a scan tool to see if it matches the actual throttle position.
If necessary, replace the TPS sensor and clear the fault code.
Remember to perform a relearn procedure if required for proper sensor calibration.
FAQ
Common causes of OBD code P0221 in a Hyundai: faulty TPS, open/shorted TPS harness, poor TPS circuit connection, faulty throttle body motor, or APP sensor issues.
Diagnose P0221 in Hyundai: Check TPS harness for shorts, poor connections, or faulty TPS. Inspect wiring for damage or corrosion. Repair as needed.
