Common Questions

What does B087F mean and how does it affect my car?

B087F indicates a malfunction in the transmission range sensor. This can cause erratic shifting, prevent the vehicle from starting, and may eventually lead to severe transmission issues. If ignored, it could escalate to costly repairs.

What are the most common causes of B087F and how much does it cost to fix?

The most common causes include a faulty transmission range sensor, damaged wiring, or low transmission fluid. Repair costs can range from $150 for sensor replacement to $100 for wiring repairs, varying by the vehicle make and model.

Can I drive my car with B087F or should I stop immediately?

Driving with code B087F is not advisable as it can lead to further transmission damage. If your vehicle shows symptoms like slipping gears or failure to start, it's best to stop and have it diagnosed.

How can I diagnose B087F myself using GeekOBD APP?

Using the GeekOBD APP, connect it to your vehicle's OBD2 port, retrieve diagnostic codes, and access freeze-frame data. Look for the B087F code and any related codes to understand the context of the problem.

What vehicles are most commonly affected by B087F?

Commonly affected vehicles include the 2015-2018 Ford F-150 and the 2017 Chrysler Pacifica, as these models often experience issues with their transmission range sensors.

How can I prevent B087F from happening again?

To prevent B087F, regularly check transmission fluid levels, perform routine maintenance, and address any electrical issues promptly. Keeping connections clean and secure can also help.

What is B087F?

The diagnostic trouble code B087F is specific to issues related to the vehicle's electronic transmission control system, particularly indicating a fault in the transmission range sensor circuit. This code is particularly common in various Ford and Chrysler models from the years 2014 to 2020. When this code is triggered, the vehicle's transmission may not shift properly, leading to erratic shifting, difficulty in engaging gears, or even complete transmission failure if left unaddressed. The transmission range sensor is integral to ensuring that the vehicle knows which gear it is in and can adjust accordingly. If the vehicle's computer detects an anomaly in the reading from the transmission range sensor, it activates the B087F code. Car owners may experience symptoms like the check engine light illuminating, issues with the transmission slipping, or the vehicle failing to start in certain gears. The longer the issue persists without repair, the more extensive the damage could become, potentially leading to costly repairs. Therefore, it’s crucial for drivers to be aware of this code and seek diagnostics if they encounter it, ideally using tools like the GeekOBD APP to pinpoint issues quickly.

Symptoms

Common symptoms when B087F is present:

  • Check engine light illuminates and stays on, indicating a fault in the transmission system.
  • Transmission may hesitate or jerk when shifting gears, affecting driving smoothness.
  • Vehicle may fail to start in certain gears, leading to frustration and potential safety hazards.
  • Fuel economy may decrease as the vehicle struggles to shift efficiently.
  • Unusual noises from the transmission area, such as grinding or whining sounds.

Possible Causes

Most common causes of B087F (ordered by frequency):

  1. The most common cause of code B087F is a malfunctioning transmission range sensor, which accounts for about 70% of cases. This sensor can fail due to wear and tear or electrical issues.
  2. Another common cause is damaged wiring or connectors in the transmission circuit, which can lead to poor communication between the sensor and the vehicle's computer.
  3. A third potential cause is low transmission fluid levels, which can affect the overall performance of the transmission system and lead to sensor read errors.
  4. Less common but serious causes include internal transmission damage, which may require extensive repairs or a complete overhaul.
  5. A rare cause could be a faulty engine control module (ECM), which may not interpret the sensor's signals correctly, leading to erroneous codes.
