P1120 throttle plate
P1138 throttle position sensor 1
P1140 throttle potentiometer 2
P0103 hot film MAF sensor
P0132 o2 sensor before cat
P0152 o2 sensor before cat
P0138 02 behind cat
P0158 o2 behind cat
Sounds to me like all of these are connected in a circuit that’s shorted out somewhere.
Pedal value is 30.08%
Pedal encoder potentiometers are reading 4.54v
Actual value throttle is 118% even though it’s fully closed
Throttle position sensor 1&2 are both getting 5v
I’m truly at a loss. I pulled my ecu and everything looks okay nothing obvious, I saw some weird cracking but not sure if it’s just age or what. This car is supposed to get in the body shop the end of this week and I still don’t even know if it’s going to be totaled out or not. Would love to get back running again. Any help will be greatly appreciated.

Throttle position sensor and the throttle potentiometer could be on the same circuit.
But O2 sensor and MAF with the above??? very doubtful.
I would look at a wiring schematic and see if they have a common ground.
A bad common ground for the circuits or for the ECU "could" cause your issue.
