Common Questions

What does P087F mean and how does it affect my car?

DTC P087F indicates a performance issue with the transmission fluid temperature sensor. This sensor is crucial for optimal transmission operation, and if it fails, your vehicle may experience harsh shifting, decreased fuel efficiency, and potential transmission failure. It's important to address this issue promptly to avoid costly repairs and ensure safe driving.

What are the most common causes of P087F and how much does it cost to fix?

The most common cause of P087F is a faulty transmission fluid temperature sensor, with repair costs typically ranging from $150 to $300. Other causes can include wiring issues or low fluid levels, which can also be fixed for a similar cost. Regular maintenance can help prevent these issues.

Can I drive my car with P087F or should I stop immediately?

It’s advised to stop driving your vehicle if you see the P087F code. Continuing to drive can lead to severe transmission damage, increased repair costs, and potential safety risks, such as stalling or loss of control.

How can I diagnose P087F myself using GeekOBD APP?

To diagnose P087F using the GeekOBD APP, start by connecting the app to your vehicle's OBD2 port. Scan for trouble codes and freeze frame data. Check the live data for transmission fluid temperature readings to determine if the sensor is functioning properly.

What vehicles are most commonly affected by P087F?

P087F is commonly seen in vehicles such as the 2015-2018 Chevrolet Silverado, 2015-2018 GMC Sierra, and 2011-2017 Ford F-150. It's important to keep an eye out for any recalls or technical service bulletins related to these models.

How can I prevent P087F from happening again?

Prevent P087F by performing regular maintenance on your transmission, including fluid changes and inspections. Ensure electrical connections are clean and free from corrosion, and address any warning signs immediately.

What is P087F?

DTC P087F refers to a diagnostic trouble code indicating a performance issue with the transmission fluid temperature sensor. This sensor plays a critical role in monitoring the temperature of the transmission fluid, which is essential for ensuring proper transmission operation. When the engine control module (ECM) detects that the temperature readings from the sensor are outside the expected range, it triggers this code. This can lead to various transmission problems, including harsh shifting, slipping, or even complete transmission failure if left unaddressed. Commonly found in vehicles like the Chevrolet Silverado (2015-2018), GMC Sierra (2015-2018), and Ford F-150 (2011-2017), the P087F code signals a need for immediate attention. The implications of ignoring this code can lead to increased wear and tear on the transmission components, decreased fuel efficiency, and potentially costly repairs. Drivers may notice warning lights on their dashboards, and the vehicle may exhibit abnormal behavior such as stalling or difficulty in shifting gears. Therefore, understanding and addressing the P087F code is crucial for maintaining vehicle performance and reliability.

Symptoms

Common symptoms when P087F is present:

  • Check engine light stays on constantly, indicating a persistent issue that needs attention.
  • Engine hesitates during acceleration, causing a frustrating driving experience and potential safety hazards.
  • Fuel economy decreased by 10-15%, leading to increased costs at the pump and reduced efficiency.
  • Unusual transmission behavior, such as slipping or jerking during gear shifts, which can affect drivability.
  • Delayed or harsh shifting, particularly noticeable during stop-and-go traffic, which can be uncomfortable for drivers.

Possible Causes

Most common causes of P087F (ordered by frequency):

  1. Faulty transmission fluid temperature sensor, which is the most common cause at around 60% likelihood; this sensor may fail due to age or exposure to extreme temperatures.
  2. Wiring issues or poor connections, accounting for about 25% of cases; damaged wiring can disrupt the signal sent to the ECM.
  3. Issues with the transmission control module (TCM), which can malfunction and misinterpret sensor readings; regular maintenance can help prevent this.
  4. Fluid contamination or low transmission fluid levels can also trigger the P087F code, emphasizing the importance of routine fluid checks.
  5. Rarely, internal transmission problems may arise, which can be costly to repair and require professional diagnosis.
