00287 DTC Code: Causes, Symptoms, and Solutions


Have you recently encountered the 00287 DTC code on your vehicle’s diagnostic system? If so, you’re probably wondering what this code means and what steps you should take to address the issue. In this article, we will provide you with a deep understanding of the 00287 DTC code, its potential causes, symptoms, and effective solutions. So, let’s dive right into it!

Understanding the 00287 DTC Code

The 00287 DTC code refers to a specific problem identified by the vehicle’s onboard diagnostic system. DTC stands for Diagnostic Trouble Code, and these codes are standardized across all vehicles equipped with an OBD system. When a fault or abnormality is detected within a specific area of the vehicle, the corresponding DTC is generated. In the case of the 00287 DTC code, it typically indicates an issue related to the vehicle’s transmission.

Causes of the 00287 DTC Code

Multiple factors can trigger the 00287 DTC code. Here are some of the most common causes:

  1. Faulty Transmission Speed Sensor: One possible cause of the 00287 DTC code is a malfunctioning transmission speed sensor. This sensor provides the vehicle’s control module with information regarding the rotational speed of the transmission output shaft.

  2. Damaged Wiring or Connectors: Another potential cause is damaged or disconnected wiring within the transmission system. Corrosion, physical damage, or loose connections can disrupt the transmission speed sensor’s proper operation and result in the 00287 DTC code.

  3. Transmission Control Module (TCM) Failure: A faulty TCM can also trigger the 00287 DTC code. The TCM is responsible for controlling the transmission’s shifting and other related functions. If it fails to operate correctly, it can cause the DTC code to appear.

Symptoms of the 00287 DTC Code

When the 00287 DTC code is present, you may experience various symptoms that can hint at a transmission-related issue. Here are some common symptoms associated with this code:

  • Warning Light: The most obvious symptom of the 00287 DTC code is the illumination of the “Check Engine” or “Transmission” warning light on your vehicle’s dashboard.

  • Transmission Issues: Additionally, you may notice irregularities in your vehicle’s shifting behavior, such as slipping gears, delayed engagement, or difficulty in shifting between gears.

  • Poor Performance: If the 00287 DTC code is affecting your vehicle’s transmission, you may also experience reduced power, decreased fuel efficiency, or even complete loss of power.

Solutions for the 00287 DTC Code

Resolving the 00287 DTC code requires a systematic approach and, in some cases, the expertise of a professional mechanic. Here are some possible solutions to consider:

  1. Inspect and Repair Wiring: Start by visually inspecting the wiring and connectors associated with the transmission speed sensor. Look for signs of damage, corrosion, or loose connections. Repair or replace any faulty components as necessary.

  2. Replace Transmission Speed Sensor: If the wiring and connectors are in good condition, the transmission speed sensor itself may be faulty. In this case, replacing the sensor should clear the 00287 DTC code.

  3. Check and Repair TCM: If the above steps didn’t resolve the issue, consider checking the TCM for any signs of failure. The TCM may need to be repaired or replaced by a qualified professional to eliminate the 00287 DTC code.

Frequently Asked Questions

  1. Q: Is it safe to continue driving with the 00287 DTC code?

    • A: It is generally recommended not to ignore the 00287 DTC code, as it can indicate significant transmission issues. Continuing to drive without resolving the problem may lead to further damage and expensive repairs.
  2. Q: Can I reset the 00287 DTC code myself?

    • A: While you may be able to clear the code temporarily by disconnecting the vehicle’s battery, it’s crucial to address the root cause of the code. Resetting the code without addressing the underlying issue will likely result in its reappearance.
  3. Q: How much does it cost to fix the 00287 DTC code?

    • A: The cost of fixing the 00287 DTC code can vary depending on the specific cause and the vehicle model. Repairs may range from relatively inexpensive, such as fixing wiring issues, to more costly, such as replacing the TCM. Contacting a professional mechanic for an accurate diagnosis and cost estimate is recommended.


The 00287 DTC code indicates a transmission-related issue that requires attention. By understanding its causes, recognizing the symptoms, and pursuing the appropriate solutions, you can ensure the efficient and reliable operation of your vehicle. Remember to address the code promptly to prevent further complications. If you’re unsure or uncomfortable with diagnosing and repairing the issue yourself, consult a certified mechanic for professional assistance.
