Order of inspection
P2124 Throttle/Pedal Position Sensor/Switch D Circuit Intermittent High
The P2124 code means the signal from the pedal or throttle position sensor D drops out or jumps intermittently. The main effect is limp mode with limited power. A bad contact in the connector or a damaged wire is almost always behind it, and you find it by reproducing the fault.
