p060b, p2104, p2110 codes - in failsafe engine mode

Did anybody ever resolve the " P060B, P2104, P2110 dilemma? Mine started after replacing the throttle body and pedal sensor. Mechanic said it was the PCM computer. The throttle body and pedal sensor were aftermarket. Have read that could be causing it. Mine is a 2008 Base Mustang with 133,000 ish miles on it. All stock except aftermarket sensors. Wanted input before replacing PCM

The stock PCM rarely fails and when it does, it's invariably because someone stupidly managed to short it out.
I'd say either the aftermarket TB or pedal sensor is faulty right out of the box.
