Order of inspection
P0221 Throttle/Pedal Position Sensor/Switch B Circuit Range/Performance High
The P0221 code means the second throttle position signal is inside valid ranges but does not behave as it should, showing jumps, dead spots or an inconsistent progression. It is usually caused by wear on the potentiometer track in the rest zone, where it works the most.
