Throttle Position Sensor
Reports how far the throttle plate is open. On drive-by-wire systems it is one of two or three redundant sensors reporting the same movement on different voltage slopes, so that no single failure can convince the module the driver is asking for power they are not.
Also known as: tps, throttle sensor, throttle pot, throttle potentiometer, tp 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.
