P2113
Throttle/Pedal Position Sensor B Minimum Stop Performance
Throttle actuator control
Generic OBD-II
Medium
What it means
P2113 sets when throttle position sensor B doesn't reach the expected voltage at its closed (minimum) stop, so the ECM can't trust where "closed throttle" really is. It's usually caused by carbon buildup in the throttle bore or a failing sensor, and often puts the car into a reduced-power limp mode.
Medium
Can I keep driving? Usually drivable, but the car can drop into a reduced-power limp mode with sluggish throttle response until it's fixed.
Common symptoms
What you'll notice
- Check-engine light on
- Reduced power, often a limp/failsafe mode
- Hesitation or surging when you first press the throttle
- Rough or unstable idle
Common causes
Most likely first
- Carbon buildup in the throttle bore skewing the learned closed (minimum-stop) positionLikely
- Faulty throttle position sensor B or throttle body assemblyCommon
- Open, shorted, or chafed sensor signal wiringCommon
- Poor connection or corrosion at the throttle/pedal sensor connectorLess often
- Rarely, a faulty ECM/PCMLess often
How to diagnose & fix
Work through it in order
- Read freeze-frame data and confirm the B sensor circuit is the one flagged.
- Inspect and clean the throttle bore and plate, then relearn the throttle closed/idle position.
- Backprobe the sensor connector (key on, engine off) for a steady 5V reference and a good ground.
- Wiggle-test the harness and connector for opens, shorts, or corrosion.
- If the reference and ground are good and buildup is cleared, replace the throttle body/sensor and retest.
FAQ
Quick answers
Is it safe to drive with P2113?+
Short trips are usually fine, but the car may enter a reduced-power limp mode with poor throttle response, so get it fixed soon.
Can I just clear P2113?+
It returns until the throttle body is cleaned and relearned or the sensor/wiring is repaired.
