What is P0924?

The diagnostic trouble code (DTC) P0924 indicates a range or performance problem with the transmission fluid pressure sensor or switch 'A'. This code is primarily associated with modern vehicles equipped with automatic transmissions, including popular models like the 2014-2018 Ford F-150 and the 2013-2017 Dodge Ram 1500. When this code is triggered, it means that the Engine Control Module (ECM) has detected that the signal from the transmission fluid pressure sensor is either out of the expected range or is not functioning properly. This can lead to various performance issues, including erratic shifting, slipping gears, or even complete transmission failure in severe cases. In real-world terms, drivers may experience symptoms like the check engine light coming on and poor vehicle performance, which can be both frustrating and potentially dangerous. Ignoring this code can result in more extensive damage to the transmission system, leading to costly repairs. Therefore, it is crucial for car owners to understand what this code means and to address it promptly to maintain vehicle safety and reliability.

System: P - Powertrain (Engine, Transmission, Emissions)

Symptoms

Common symptoms when P0924 is present:

  • Check engine light stays on constantly, indicating a fault detected in the transmission system.
  • Transmission may hesitate or jerk during acceleration, leading to a jerky driving experience.
  • Fuel economy decreased by 10-15%, as the vehicle may work harder to compensate for transmission issues.
  • Delayed or harsh shifting between gears, making the driving experience uncomfortable.
  • Unusual noises coming from the transmission area, which might indicate internal damage.

Possible Causes

Most common causes of P0924 (ordered by frequency):

  1. The most common cause of P0924 is a faulty transmission fluid pressure sensor, which has a likelihood of about 60%. This sensor is essential for monitoring fluid pressure and ensuring proper transmission function.
  2. A second common cause can be electrical issues, such as damaged wiring or poor connections, affecting the sensor's operation. This can lead to intermittent signals and erratic shifting.
  3. A third cause might be low transmission fluid levels due to leaks; therefore, regular checks of fluid levels can help prevent this issue.
  4. Less common but serious causes include internal transmission malfunctions, which could necessitate a complete transmission rebuild.
  5. A rare cause could be a software glitch in the ECM, which may require a reprogramming or update to resolve the issue.
