P0124 Code: Sensor/Interruptor de Posición del Acelerador/Pedal A Circuito Intermitente
CodePage.genericDisclaimer
¿Qué significa esto?
El código P0124 indica una falla eléctrica intermitente en el circuito 'A' del Sensor de Posición del Acelerador (TPS) o del Sensor de Posición del Pedal del Acelerador (APPS). Esto significa que el voltaje de la señal del sensor 'A' no es estable y presenta caídas, picos o lecturas erráticas de forma intermitente, lo que el Módulo de Control del Tren de Potencia (PCM) interpreta como una falla. Esto puede llevar a un comportamiento impredecible del motor, como titubeos, tirones, pérdida de potencia o incluso el calado.
CodePage.howSerious
Un sensor de posición del acelerador intermitente puede provocar una velocidad del motor impredecible, aceleración o desaceleración repentina, pérdida de potencia o incluso el calado. Esto representa un riesgo de seguridad significativo, especialmente al conducir en tráfico o a velocidades de autopista, ya que puede comprometer el control del vehículo. Se recomienda encarecidamente diagnosticar y reparar este problema de inmediato.
Diagnostic system: Sensor circuit and live data
On a Tesla Model-3, the P0124 code should be diagnosed as part of the sensor circuit and live data group. Related codes and live data from this same system can change the repair priority, so avoid replacing parts from the code name alone.
Most Common Causes for Tesla Model-3
- Sensor de posición del acelerador (TPS) defectuoso
- Arnés de cableado dañado o roto
- Conector eléctrico corroído o suelto
Síntomas a tener en cuenta
- La luz de Check Engine está encendida
- RPM del motor fluctuante
- Titubeo o tropiezo al acelerar
- Velocidad de ralentí errática o fluctuante
CodePage.beforeReplacing
- Inspect the connector for corrosion, broken locks, oil intrusion, or heat damage.
- Verify 5V reference, ground, and signal with a multimeter where applicable.
- Compare live sensor data to realistic engine temperature, pressure, airflow, or throttle values.
- Check for blown fuses, weak battery voltage, and damaged connectors before buying major parts.
Cómo Diagnosticar
CodePage.commonMistakes
Replacing the named sensor without testing power, ground, signal, and wiring continuity first. Always confirm the fault with freeze-frame data, live data, visual inspection, and circuit checks before spending money on parts.
CodePage.faq
Can I drive with the P0124 code?
If the check engine light is solid, you can usually drive to a safe location or mechanic. If the light is flashing, pull over immediately to prevent catastrophic engine or catalytic converter damage.
Will the P0124 code clear itself?
Once the underlying problem is fixed, the engine computer will run its self-checks. If it passes over several drive cycles, the light will turn off automatically. You can also clear it immediately using an OBD2 scanner.
Will this code fail an emissions test?
Yes. If the Check Engine Light is on due to the P0124 code, your Tesla will automatically fail an OBD2 plug-in emissions or smog test.
What should I check first for P0124?
Inspect the connector for corrosion, broken locks, oil intrusion, or heat damage. Verify 5V reference, ground, and signal with a multimeter where applicable. Compare live sensor data to realistic engine temperature, pressure, airflow, or throttle values.

Estimación de reparación
Fuse, connector, wiring, cleaning, or basic inspection
Major component replacement after live data and circuit tests confirm failure
Sensor replacement can be moderate cost, but wiring and connector repairs are common and cheaper.
Dificultad de reparación (DIY)
Can usually be performed at home with basic hand tools.
