P0463 - CEL - Goes into Reduced Power Mode......After researching the P0463 code - Fuel Level Circuit Low Input - I had a local mechanic change the fuel tank sending unit. He said the gauge still was stuck on empty and did not complete the install. More research - Could be the Throttle body Sensor? - Could Be the Instrument cluster ? Truck runs Great!! Although it goes into reduced power mode every once in a while. I pull off and shut it down....wait 1-2 minutes and start her up and she is good for another week or so. Fuel gauge is stuck on empty, which is a pain. The fuel gauge being stuck on empty - could very well be the instrument cluster....but will that cause the REDUCED POWER MODE???? HELP!!!
