Common Questions

What does P087E mean and how does it affect my car?

The P087E code indicates a problem with the transmission fluid pressure sensor circuit's range or performance. This can lead to poor shifting, slipping gears, and potential damage to the transmission. Addressing this issue promptly is essential for maintaining vehicle performance.

What are the most common causes of P087E and how much does it cost to fix?

The most common causes of P087E include a faulty transmission fluid pressure sensor, wiring issues, and low transmission fluid levels. Repair costs can range from $150 for sensor replacement to over $1,200 if the transmission control module needs replacing.

Can I drive my car with P087E or should I stop immediately?

It's advisable to minimize driving if you see the P087E code, as continuing to drive can lead to serious transmission damage. If you must drive, do so cautiously and avoid heavy acceleration.

How can I diagnose P087E myself using GeekOBD APP?

To diagnose P087E with GeekOBD APP, connect the device to your vehicle's OBD2 port, run a complete scan to retrieve codes, and check the freeze frame data to analyze the conditions when the code was triggered.

What vehicles are most commonly affected by P087E?

The P087E code is commonly seen in models such as the 2015-2018 Ford F-150 and the 2016-2019 Chevrolet Silverado. Always check for manufacturer recalls or technical service bulletins related to this code.

How can I prevent P087E from happening again?

Regularly check and maintain your transmission fluid levels, get periodic inspections of the transmission system, and address any electrical issues promptly to prevent the recurrence of P087E.

What is P087E?

The diagnostic trouble code (DTC) P087E indicates a problem with the transmission fluid pressure sensor circuit, specifically relating to range or performance. This code is prevalent in various makes and models, particularly in vehicles like the 2015-2018 Ford F-150 and 2016-2019 Chevrolet Silverado. When the engine control unit (ECU) detects that the signal from the transmission fluid pressure sensor is outside the expected range, it triggers this code. The transmission fluid pressure sensor is crucial for monitoring the hydraulic pressure within the transmission, which directly impacts shifting performance and overall transmission functionality. When P087E is triggered, it can lead to several issues, including harsh shifting, slipping gears, or even the vehicle going into limp mode to prevent further damage. Drivers may notice that their vehicle doesn't accelerate smoothly or experiences a delay in shifting. Ignoring this code can lead to severe transmission damage, resulting in costly repairs. For instance, if the sensor fails, it could cause the transmission to operate under incorrect pressure, leading to overheating and premature wear. Therefore, understanding and addressing P087E promptly is crucial for maintaining vehicle performance and longevity.

Symptoms

Common symptoms when P087E is present:

  • Check engine light illuminates and remains on, indicating an underlying issue that needs immediate attention.
  • Harsh or erratic shifting can occur, making it feel like the vehicle is slamming into gear during transitions.
  • Engine hesitates during acceleration, which may feel like a loss of power when trying to increase speed.
  • Decreased fuel economy, which may be noticeable as a 10-15% drop in miles per gallon due to inefficient transmission operation.
  • Transmission may enter limp mode, limiting vehicle speed and functionality to prevent further damage.

Possible Causes

Most common causes of P087E (ordered by frequency):

  1. Faulty transmission fluid pressure sensor: This is the most common cause, accounting for approximately 50% of cases. A failing sensor can provide inaccurate readings, leading to the P087E code.
  2. Wiring issues: Damaged or corroded wires in the transmission pressure sensor circuit can disrupt the signal being sent to the ECU. Regular checks can help prevent wiring issues.
  3. Low transmission fluid level: A lack of adequate fluid can cause pressure drops, triggering the code. Routine maintenance and fluid checks can mitigate this risk.
  4. Transmission control module (TCM) failure: Although less common, this can impact sensor readings and lead to erroneous codes. If other issues are ruled out, the TCM may need testing.
  5. Mechanical issues within the transmission itself, such as worn components, can also lead to this error, though these cases are rare.
