Accelerator Pedal Position Sensor
Reports how far the driver has pressed the pedal. On drive-by-wire vehicles there is no cable to the throttle, so this signal is the only expression of driver intent — which is why it is duplicated and why disagreement between the copies triggers a limp mode rather than a guess.
Also known as: app sensor, apps, pedal sensor, pedal position sensor, throttle pedal sensor, gas pedal sensor

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.
