P2113

Throttle/Pedal Position Sensor B Minimum Stop Performance

Q: 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.

Q: Can I just clear P2113?

It returns until the throttle body is cleaned and relearned or the sensor/wiring is repaired.

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.
