What is B0F54?

DTC B0F54 is a diagnostic trouble code that indicates a malfunction in the fuel level sensor circuit within the vehicle's powertrain control module (PCM). This code is particularly common in models such as the 2015-2020 Toyota Camry and RAV4. When this code is triggered, it generally means that the PCM has detected a discrepancy in the readings provided by the fuel level sensor, which is responsible for measuring the amount of fuel in the tank. A malfunctioning fuel level sensor can lead to inaccurate fuel readings, leaving drivers unaware of their actual fuel level. This can result in running out of fuel unexpectedly, which poses risks to driver safety and could lead to engine damage if the vehicle runs dry. Ignoring this code can also result in poor fuel economy, as the engine may not operate at optimal efficiency without proper fuel level management. Therefore, it is essential to address DTC B0F54 promptly to ensure the vehicle’s reliability and performance.

Symptoms

Common symptoms when B0F54 is present:

  • The check engine light remains on, indicating a persistent issue that needs attention.
  • Drivers may notice the fuel gauge displaying erratic readings, making it difficult to determine fuel levels accurately.
  • Fuel economy may decrease significantly, with reports of up to 15% reduction in efficiency due to improper fuel management.
  • The vehicle may experience stalling or hesitation during acceleration, which can occur if the engine is not receiving the correct fuel supply.
  • In some cases, the dashboard may show a 'Low Fuel' warning even when the tank is nearly full.

Possible Causes

Most common causes of B0F54 (ordered by frequency):

  1. The most common cause of DTC B0F54 is a faulty fuel level sensor, which has a likelihood of around 60%. This sensor can wear out over time due to exposure to heat and fuel vapors.
  2. Another cause may be damaged wiring or connectors in the fuel level sensor circuit, which can disrupt signals being sent to the PCM.
  3. Issues with the PCM itself can also trigger this code, though this is less common. Regular software updates and maintenance can help prevent such failures.
  4. In rare instances, the problem can stem from a defective fuel pump, which can affect the overall fuel delivery system and cause inaccurate readings.
  5. Environmental factors, such as corrosion from moisture or debris in the fuel tank, can also lead to sensor malfunction.
