2004 Toyota Camry LE 2.4L MIL Lamp on, No acceleration VIN: 4T1BE32K54
P2121: Accelerator Pedal Position Sensor Performance. ... sudden no acceleration. Check Engine Light Came on. P2121 Code. Turned Engine off then restarted it then Pedal Acceleration was responsive. Toyota has a TSB for a Throttle Body issue but I don't think it applies this this problem.
