P2113 Throttle/Pedal Position Sensor B Minimum Stop Performance

Check engine lightOn
EmissionsRelevant
Drive cycleNot required
Limp modePossible

The engine computer checks whether position signal B reports a plausible value when the throttle or pedal rests against its lower mechanical stop. At key-on many systems learn this minimum and compare it with a tolerance window; a reading outside that window sets the code. Ford and GM label their second throttle position sensor as B, so on those layouts B means the throttle body, but neither maker publishes P2113 itself. No manufacturer documents this code publicly; Subaru uses the A version (P2109). Ice, coking or a bent stop are typical triggers. P0220-P0223 cover the B circuit, P2109 and P2114-P2117 the other letters. The driver may see a warning lamp and reduced power.

Likely causes

Carbon deposits or ice keep the throttle plate off its rest stop
Position sensor B worn or drifted at the low end of its track
Minimum position not relearned after cleaning or part replacement
Corroded connector shifting the sensor B signal

Symptoms

  • Engine or ETC warning lamp on
  • Unstable or raised idle speed
  • Reduced engine power (limp mode)

Repair estimate
