P0121 2007 chevy silverado

My check engine light came on and when i scan it i get a "PO121 throttle pedal position sensor a circuit range performace" code. I replaced the throttle pedal with the sensor built on it. The next day my light was back on showing the same code. I'm at a lose here. Any advice or tips would be much appreciated. Thanks
