Re: P2121 and P2122 OBD codes, "Reduced Engine Performance" message, engine will not rev above 1,000 RPM in Drive on 200
UPDATE! Problem solved! I removed the FMI1 relay for the A/C, replaced the 10A fuse in the #8 position of the underhood fuse box and everything was normal again. Now, my next task is to track down the short in the A/C compressor/clutch wiring. Luckily, here in the Pacific NW, I won't be needing A/C ...

Have you checked the fuses in the engine compartment? I read one of the fixes for these codes was replacing a blown 10A fuse (slot 11?) in the engine compartment, It's the fuse for the accelerator pedal sensor, cooling fan for electronics box engine compartment and AC compressor solenoid switch. I ...
