Code U1424 Jeep Description
The U1424 code for Jeep vehicles indicates that an implausible engine torque signal has been received by the Engine Control Module (ECM). This means that there is a discrepancy between the expected engine torque and the actual engine torque being produced by the vehicle. This can lead to a variety of performance issues, including rough idling, hesitation during acceleration, decreased fuel efficiency, and potentially even engine stalling. The code is typically triggered when the ECM detects a signal that is outside of the normal operating range, indicating a malfunction in the engine torque sensor or a related component.
Common Causes of U1424 Jeep
- Faulty engine torque sensor
- Wiring or connector issues in the engine torque sensor circuit
- ECM software issues
- Mechanical problems in the engine affecting torque output
- Inaccurate engine torque calculations due to sensor malfunctions
Symptoms of U1424 Jeep
- Rough idling or engine misfires
- Hesitation or lack of power during acceleration
- Decreased fuel efficiency
- Engine stalling
- Illumination of the check engine light
How to Fix U1424 Jeep
- Perform a thorough inspection of the engine torque sensor and its wiring for any signs of damage or corrosion.
- Test the engine torque sensor using a multimeter to check for proper voltage and resistance readings.
- Check and reset the ECM to clear any stored fault codes and recalibrate the engine torque sensor.
- If necessary, replace the engine torque sensor with a new, OEM-quality part.
- After the repair, conduct a test drive to ensure that the engine torque signal is now within the expected range and that the vehicle's performance has been restored.
Cost to Fix U1424 Jeep
The typical repair costs for addressing an implausible engine torque signal code like U1424 in a Jeep can range from $200 to $500, including parts and labor. However, the specific diagnosis time and labor rates at auto repair shops can vary based on factors such as location, vehicle make and model, and engine type. It's recommended to check with local repair shops for a more accurate estimate.

I changed the oil cooler on a 2015 Jeep
Cherokee trailhawk. I had to remove the plenum and air intake manifold. After installing the new cooler, reinstalling the plenum and manifold, my Jeep went into limp mode showing
Codes U1424, P0456, P0457, P0441. Any advice is appreciated. -
P0456, P0457, P0441 Codes are for the EVAP system and will not send the engine into a limp mode. Check for loose or misplace EVAP system hoses.
For the U1424 check Battery for proper State of Charge (SOC) and Charging System for proper operation.
Have you try clearing the codes?

I’ve found the problem. I cleared the codes and let it idle. All the codes returned, the dashboard flashed electronic throttle control. I removed the air filter assembly and hoses connected to the throttle body. I found a small piece of the boot/hose obstructing the butterfly from opening or closing correctly. I removed that piece of debris, cleaned and lubricated the throttle body, reassembled everything. I cranked my Jeep and everything is back to normal. The electronic throttle control light and engine light were gone. I cleared the codes and to it for a test ride. No codes. Thanks for the replies.

Bonjour ,un jeep SRT 8 2014,j'ai des codes P0335,P1DD2,U1424
j'ai changé le capteur P0335 malgré le code reste la vitesse est fige à D4 qui ne varie pas
PUI6JE AVOIR CONSEIL-
Bonjour, merci pour votre message.
Sur votre Jeep SRT8 2014, les codes P0335, P1DD2, et U1424 ensemble indiquent un problème de communication entre les capteurs moteur et le module de transmission. Le fait que la boîte reste bloquée en D4 confirme que le véhicule est probablement en mode dégradé (limp mode).
Voici une explication rapide des codes :
- P0335 : Problème de signal du capteur de vilebrequin (CKP). Même après remplacement, le code peut rester si le problème vient du faisceau ou du connecteur, pas du capteur lui-même.
- P1DD2 : Défaut de communication entre le module moteur (PCM) et le module transmission (TCM).
- U1424 : Signal de couple moteur incohérent reçu par le TCM.
Voici ce que je vous conseille de vérifier :
- Faisceau du capteur de vilebrequin – Vérifiez le connecteur, nettoyez les broches, et suivez le faisceau pour détecter toute coupure ou court-circuit. Ce capteur est très sensible à la qualité du signal.
- Masse moteur et batterie – Des masses faibles ou un voltage instable peuvent perturber la communication entre modules.
- Effacer les codes après réparation – Parfois, le code reste en mémoire tant qu’il n’est pas effacé avec un bon outil de diagnostic.
- Mise à jour logiciel ou reprogrammation – Si tout est en bon état, certains véhicules ont besoin d’une mise à jour du PCM ou TCM chez le concessionnaire pour corriger des erreurs de communication.
Votre problème semble plus lié à la communication entre modules qu’à une pièce en panne. Si vous avez accès à un outil de diagnostic complet (comme Launch, Autel ou équivalent), vous pouvez lire les données en direct pour voir si le capteur de vilebrequin donne un signal constant.
Si besoin, je peux vous aider à localiser et tester le faisceau.
