What is a DTC Code?

A DTC code is an alphanumeric identifier generated by the onboard diagnostic system of a vehicle when it detects an issue or malfunction. These codes serve as valuable clues in diagnosing and resolving problems, allowing technicians to pinpoint specific areas that require attention.

Understanding the 19463/P3007/012295 DTC Code

Definition and Description

The 19463/P3007/012295 DTC code, often encountered in Volkswagen (VW) and Audi vehicles, pertains to a significant issue related to the engine control module (ECM) and its communication with the vehicle’s transmission control module (TCM). This code indicates an implausible signal, suggesting a possible fault in the CAN (Controller Area Network) communication between these two critical systems.

Possible Causes

Several factors can trigger the 19463/P3007/012295 DTC code. Here are some potential causes to keep in mind during the diagnostic process:

  1. Faulty Transmission Control Module (TCM): A malfunctioning TCM can result in improper communication with the ECM, leading to the generation of this DTC code.
  2. Defective Engine Control Module (ECM): Similarly, an ECM that is not functioning correctly can also play a role in triggering the 19463/P3007/012295 code.
  3. Wire Harness Issues: Damaged or disconnected wires within the communication circuit can disrupt the signals between the TCM and ECM, prompting the generation of this code.
  4. Faulty Transmission Sensors: Faulty input or output speed sensors within the transmission assembly can interfere with the communication link and result in the appearance of this DTC code.
  5. Communication Bus Problems: Occasionally, signal interference on the CAN bus due to faulty connections, damaged wiring, or loose connectors can contribute to the code’s manifestation.

Diagnostic Steps

When dealing with the 19463/P3007/012295 DTC code, it is essential to follow a systematic diagnostic approach. Here is a step-by-step guide to help you identify and rectify the underlying issue:

  1. Scan the System: Utilize a diagnostic scanner capable of accessing the vehicle’s OBD-II system to retrieve the stored codes, including the 19463/P3007/012295 DTC.
  2. Inspect Wiring and Connectors: Thoroughly examine the wires, connectors, and harnesses involved in the communication circuit between the TCM and ECM. Look for any visible signs of damage, corrosion, or loose connections. Repair or replace as necessary.
  3. Check the TCM: Proceed to inspect the TCM for any physical damage or signs of electronic failure. Disconnect, clean, and reconnect the TCM, ensuring a secure connection.
  4. Test the ECM: Similarly, evaluate the ECM for potential issues. Conduct a comprehensive ECM test using the appropriate diagnostic equipment to identify any faults.
  5. Examine Transmission Sensors: Inspect the input and output speed sensors located within the transmission assembly. Ensure they are properly secured, functioning correctly, and not damaged.
  6. Verify CAN Bus Communication: Utilize diagnostics tools to check the integrity of the CAN bus communication. Look for any intermittent or faulty signals that might hinder the TCM-ECM interaction.
  7. Clear DTCs and Perform Test Drive: Clear all stored codes after completing the necessary repairs. Take the vehicle for a test drive to ensure the issue is resolved and the 19463/P3007/012295 DTC code does not reappear.

Frequently Asked Questions (FAQs)

Q1: Can I continue driving with the 19463/P3007/012295 DTC code present?

A1: While it is generally advised not to drive with any existing DTC codes, the severity of the issue depends on the specific circumstances. It is recommended to have the vehicle inspected by a qualified technician to determine if it is safe to continue driving or if immediate repairs are required.

Q2: Can a faulty battery trigger the 19463/P3007/012295 DTC code?

A2: While a faulty battery might cause temporary electrical issues, it is unlikely to directly trigger the 19463/P3007/012295 code. However, a weak battery can affect the overall performance of various systems, leading to other related problems.

Q3: How much does it cost to fix the 19463/P3007/012295 DTC code?

A3: The cost of addressing the 19463/P3007/012295 DTC code can vary depending on the underlying cause and the labor rates of the repair facility. It is advisable to consult with a trusted mechanic or dealership to obtain an accurate estimate based on your specific vehicle and location.


In conclusion, the 19463/P3007/012295 DTC code serves as a valuable indicator of a potential issue within the communication system of Volkswagen and Audi vehicles. By understanding the possible causes and following a systematic diagnostic approach, you can effectively troubleshoot and resolve this code, allowing for proper functionality of the ECM-TCM communication. Remember to seek professional assistance if needed and ensure the necessary repairs are performed to maintain the optimal performance of your vehicle.
