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

The backup throttle position sensor is sending readings that are outside the normal expected range, suggesting the sensor may be failing or its signal is unreliable. This can cause the engine to hesitate, stall, or run poorly because the computer can't accurately determine how much throttle you're applying. Have the sensor tested or replaced to restore normal operation.
