Order of inspection

  1. P2129 Throttle/Pedal Position Sensor/Switch E Circuit Intermittent High

    The P2129 code means the signal from the pedal or throttle position sensor E 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.
