The P2102 code on your 2023 Ford F-150 indicates an open circuit condition in the throttle actuator control motor. This code affects your F-150's 2.7L EcoBoost, 3.5L EcoBoost, 5.0L V8, or 3.5L PowerBoost hybrid engine's electronic throttle body motor, preventing proper throttle operation.
Understanding P2102 on F-150
The throttle actuator motor is an electric motor inside the throttle body that opens and closes the throttle plate based on driver input and PCM commands. Code P2102 sets when the PCM detects an open circuit in the motor windings or wiring, meaning no current can flow to operate the throttle.
Common Symptoms
- Check engine light on
- Engine will not respond to accelerator pedal
- Engine may only idle
- Reduced power mode or limp mode
- Vehicle may be undriveable
- Possible engine stall
- Wrench icon or throttle warning light
Primary Causes
- Faulty throttle body with open motor windings
- Broken wire in throttle body motor circuit
- Corroded or disconnected throttle body connector
- Damaged wiring harness
- PCM motor driver circuit failure
- Throttle body motor frozen or seized
Diagnostic Procedure for 2023 F-150
Check throttle body motor resistance - typically 1-5 ohms depending on specification. Compare to specification in service manual. With connector disconnected, use an ohmmeter across the motor terminals. Infinity or very high resistance indicates open motor windings. Inspect wiring between PCM and throttle body for damage. Test PCM output voltage to motor circuit when commanded. Check for seized throttle plate that may have damaged motor.
Repair Solutions
If throttle body motor tests open, throttle body replacement is required. Repair or replace damaged wiring between PCM and throttle body. Clean severely corroded connectors, though replacement is recommended if damage is extensive. After throttle body replacement, perform relearn procedure. Clear codes and verify proper throttle response through full range.
