Throttle CEL(s) No Power

Hello all!

I was driving along today and my car suddenly lost power, and went into reduced engine power mode. Normally, I know I can still get home like that, but in this case, the gas pedal did absolutely nothing to get me moving, and I had to get towed.

I plugged in my code reader and got these:

P1125
P2125
P2138

I know this is throttle system related, and i've had Accelerator pedal issues before, so I replaced it. I don't know if this is a throttle body thing, or a wiring thing, or what. Just wondering if anyone out there has any ideas!

2008 Pontiac Grand Prix, 3.8
 


P1125 - Throttle Position Sensor Intermittent
P2125 - Throttle/Pedal Position Sensor/Switch 'E' Circuit
P2138 - Accelerator Pedal Position Sensor Circuit Range/Performance

^ You should post the meanings of each to make it easier on us to understand all the codes.

It looks like the accelerator pedal position switch is out, which isn't uncommon. I'm not familiar with that system since only the series III's had them, so someone else will have to come in and describe it a bit more than I can.
