Common Questions
What does P087D mean and how does it affect my car?
The P087D code indicates an issue with the transmission fluid pressure sensor. This can lead to poor shifting, reduced fuel economy, and potential transmission damage if not addressed. It's crucial to diagnose and repair this issue to maintain your vehicle's performance.
What are the most common causes of P087D and how much does it cost to fix?
Common causes of P087D include a faulty transmission fluid pressure sensor, low transmission fluid levels, and damaged wiring. Repair costs typically range from $150 to $300 depending on the specific repairs needed.
Can I drive my car with P087D or should I stop immediately?
While you can technically drive with a P087D code, it is not advisable. Continuing to drive can lead to more severe transmission issues and higher repair costs. It's best to address the problem as soon as possible.
How can I diagnose P087D myself using GeekOBD APP?
Using the GeekOBD APP, you can connect to your vehicle's OBD2 port to read the P087D code. The app will provide freeze frame data, which helps you understand the conditions under which the code was triggered, aiding your diagnosis.
What vehicles are most commonly affected by P087D?
P087D is frequently reported in vehicles such as the 2016-2020 Ford F-150, 2017-2019 Chevrolet Silverado, and 2015-2019 GMC Sierra. Make sure to check for any recalls or technical service bulletins related to your specific model.
How can I prevent P087D from happening again?
To prevent future occurrences of P087D, maintain regular transmission fluid checks and changes, avoid towing beyond your vehicle's capacity, and have your transmission inspected periodically by a qualified technician.
What is P087D?
The Diagnostic Trouble Code (DTC) P087D indicates a problem with the transmission fluid pressure sensor or switch, specifically for 'D' range or performance. This code is commonly seen in vehicles like the 2016-2020 Ford F-150 and other models equipped with similar transmission systems. The function of this sensor is crucial as it monitors the pressure of the transmission fluid, helping the vehicle's computer determine the appropriate shifting points for optimal transmission performance. When the signal from this sensor is out of range or not received, the powertrain control module (PCM) triggers the P087D code. In real-world terms, this can lead to issues like erratic shifting, slipping gears, or even transmission overheating, which can severely affect the drivability and longevity of your vehicle. If ignored, a P087D code can lead to more severe transmission damage and costly repairs, making it essential for vehicle owners to address this code promptly.
System: P - Powertrain (Engine, Transmission, Emissions)
Symptoms
Common symptoms when P087D is present:
- The check engine light stays on constantly, indicating an issue that requires immediate diagnosis.
- Engine hesitates during acceleration, which can lead to a frustrating driving experience and potential safety hazards.
- Fuel economy decreased by 10-15%, as the transmission struggles to shift properly, causing the engine to work harder.
- Rough or harsh shifting when changing from lower to higher gears, leading to a less smooth driving experience.
- Transmission may slip or fail to engage, which can leave the driver unable to accelerate effectively.
Possible Causes
Most common causes of P087D (ordered by frequency):
- The most common cause is a faulty transmission fluid pressure sensor, which has a likelihood of about 60%. If the sensor fails, it cannot provide accurate pressure readings, leading to erratic transmission behavior.
- The second most common cause is low transmission fluid levels, which can result from leaks or inadequate maintenance. Low fluid levels can lead to overheating and increased wear on transmission components.
- A third cause could be damaged wiring or connectors related to the sensor, which can prevent proper signal transmission. Regular inspections can help prevent issues with wiring.
- Less common but serious causes include internal transmission failure, which can be catastrophic and costly to repair if not caught early.
- Rarely, but possible, is a failing powertrain control module (PCM), which can misinterpret sensor readings and lead to unnecessary repairs.
