P2113: Throttle/Pedal Position Sensor B Minimum Stop Performance

What it means

The module detects that throttle or pedal position sensor B does not behave as expected at its minimum stop. It sets the code when the sensor reading or its relationship to the expected minimum position falls outside the calibrated range.

How it works

Throttle or pedal position sensor B reports the position of its assigned component to the control module. P2113 sets when the B reading at the minimum stop, or its relationship to the expected minimum position, falls outside the calibrated range; the exact component monitored depends on the vehicle's system design.

Common causes

Most likely first.

1. Faulty position sensor
2. Throttle body contamination or sticking
3. Damaged wiring or connector
4. Throttle actuator fault
5. Control module fault

Symptoms

• Check engine light
• Reduced engine power
• Poor or uneven acceleration
• Limp mode

How to diagnose it

1. Use a scan tool to record freeze-frame data and watch the live B position reading at rest and during slow pedal or throttle movement, checking for an incorrect minimum reading or dropouts.
2. Use vehicle service information to identify whether sensor B is at the pedal or throttle body, then inspect that component's connector and wiring for loose pins, corrosion, or damage.
3. Inspect the throttle body for deposits or sticking if sensor B monitors throttle position, and follow the service procedure for checking the minimum stop.
4. Compare sensor B with any redundant position channel through the full movement range and check for a consistent relationship.
5. If the wiring and mechanism are sound, test the B sensor signal and related actuator or module circuits against the manufacturer's specification.

Common fixes

• Repair a loose, corroded, or damaged connector or wire serving position sensor B.
• Clean the throttle body if deposits are preventing it from reaching its expected minimum position.
• Replace the faulty position sensor or assembly if its B signal fails the manufacturer's checks.
• Repair a confirmed throttle actuator fault affecting the minimum position.
• Address a control module fault only after sensor, wiring, and actuator tests pass.

Can I keep driving?

If reduced power or limp mode is active, avoid fast traffic and journeys that require dependable acceleration; stop if throttle response becomes unpredictable. The vehicle may have limited ability to respond to pedal input until the minimum-position fault is corrected.
