Question about Jeep Wrangler
P0122 - Throttle Position (TP) Sensor Circuit Low Voltage
P0123 - Throttle Position (TP) Sensor Circuit High Voltage
without checking it 1st I would guess the TPS is most likely defective.
P0432 - Catalyst System Low Efficiency Bank 2, you may have to replace the Catalytic convertor, it may be worn out,
A WORD OF CAUTION: Don't use aftermarket cats, they tend to reset the same code due to compatibility issues, also replace the cat monitor sensor (looks like an O2 sensor) located just to the rear of the bank 2 cat converter.
