P2113: Throttle/Pedal Position Sensor B Minimum Stop Performance
What to do
Usually a cheap fix — throttle body cleaning and a relearn. If codes for both sensor A and sensor B are present, that points at the throttle plate itself rather than at a sensor.
What this code means
The learned closed position for sensor B no longer matches expectation. The full argument is under P2109 and applies unchanged: the position is learned, carbon moves it, and cleaning plus a relearn usually resolves it.
What B adds is the redundancy point. Sensors A and B are the deliberately-mismatched pair — different slopes or opposite directions — that make a single fault detectable. So a minimum-stop code on B alone points at that sensor's own drift, while A and B reporting together points at the mechanical position both are measuring, which is the throttle plate and its carbon.

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.
