What vehicles are most commonly affected by B0287?

DTC B0287 is commonly found in models like the 2014-2019 Dodge Ram and 2014-2019 Jeep Cherokee. Check for any recalls or technical service bulletins related to your specific vehicle.

How can I prevent B0287 from happening again?

Regular vehicle maintenance, including inspections of the brake system and wiring, can help prevent DTC B0287 from recurring. Keeping electrical connections clean and free from moisture is also essential.

What is B0287?

DTC B0287 is a diagnostic trouble code that indicates an issue with the brake pedal position sensor (BPPS). This sensor plays a crucial role in conveying the position of the brake pedal to the vehicle's electronic control unit (ECU). When this sensor fails or sends incorrect signals, the ECU cannot accurately determine whether the brake pedal is engaged, which can lead to various operational problems. Commonly found in vehicles such as the 2014-2019 Dodge Ram and the 2014-2019 Jeep Cherokee, this code often triggers the check engine light and can negatively affect vehicle safety systems like traction control and anti-lock brakes. If left unresolved, the consequences can range from decreased fuel efficiency to more serious safety hazards, making it essential for car owners to diagnose and fix the underlying issues promptly. Addressing DTC B0287 typically involves inspecting wiring, checking the sensor for faults, and possibly replacing the brake pedal position sensor if it is found to be defective.

Symptoms

Common symptoms when B0287 is present:

  • The check engine light illuminates and remains on, indicating a potential issue that needs to be addressed.
  • The vehicle experiences erratic braking behavior, such as the brakes engaging without pressing the pedal, which can be alarming and dangerous.
  • Drivers may notice a significant drop in fuel economy, with reports suggesting a decrease of 10-15% due to improper braking system function.
  • In some cases, the vehicle may fail to start if the ECU cannot determine the brake pedal's status, leading to frustrating delays.
  • The anti-lock braking system (ABS) warning light may also turn on, indicating that the vehicle's safety systems are compromised.

Possible Causes

Most common causes of B0287 (ordered by frequency):

  1. The most common cause of DTC B0287 is a faulty brake pedal position sensor, which can occur in about 60% of cases. This failure often results from wear and tear over time or exposure to moisture and road debris.
  2. Another frequent issue is damaged wiring or poor connections in the sensor circuit, accounting for roughly 25% of cases. Corrosion or frayed wires can disrupt the flow of information to the ECU.
  3. Improper installation or adjustment of the brake pedal position sensor can also trigger this code, especially during prior repairs or replacements, making it crucial to follow manufacturer specifications.
  4. Less commonly, a malfunctioning ECU may misinterpret sensor signals, leading to this error code. This scenario is rare but can complicate repairs significantly.
  5. In very rare instances, software glitches in the vehicle's onboard computer system may cause DTC B0287 to appear, necessitating a software update or reprogramming.
