P2129: Throttle/Pedal Position Sensor/Switch E Circuit Intermittent
Do not keep driving
Brief losses of power that then recover deserve prompt attention rather than being lived with. Mention whether they relate to pedal position or to rough surfaces.
What this code means
Sensor E's signal drops out or jumps briefly, producing momentary power restrictions. The urgency argument under P2124 applies unchanged: a power loss that comes and goes is worse to drive with than one that stays, because it arrives without warning at whatever moment it chooses.

Information, not instruction
CarGeek is a reference, not a service manual. Its pages are written from public sources and from what other people have found, never from a manufacturer's own service information, so they can be wrong or incomplete for your particular vehicle. Some of what they describe carries real risk: high voltage, fuel under pressure, stored energy, hot and moving parts.
Have anything you intend to act on checked by a trained person against the manufacturer's own procedure for your vehicle. Nothing here replaces that procedure.

What makes one worth reading:
- The car — make, model, year and engine. The same fault behaves differently on each.
- What you measured, not only what you replaced.
- What actually fixed it — or that nothing did, which is worth knowing too.
