17519/P1111 DTC Code


In the world of automotive diagnostics, DTC codes play a vital role in identifying and troubleshooting issues with vehicles. One such code, the 17519/P1111 DTC code, often raises concerns among car owners. In this article, we will take a closer look at what this code means, its potential causes, and possible solutions to resolve the issue.

Understanding the 17519/P1111 DTC Code

The 17519/P1111 DTC code is an engine diagnostic trouble code that refers specifically to a fault related to the Engine Control Module (ECM). More specifically, this code indicates an issue with the Engine Torque Monitoring Control.

When this fault code is stored in the vehicle’s ECM, it triggers a check engine light on the dashboard. Therefore, if you come across this code during your vehicle’s diagnostic scan, it’s important not to ignore it and take necessary steps to address the underlying issue.

Potential Causes of 17519/P1111 DTC Code

Now, let’s explore some of the potential causes that could trigger the 17519/P1111 DTC code:

  1. Faulty Engine Torque Monitoring System: The Engine Torque Monitoring System plays a crucial role in monitoring the torque produced by the engine. A malfunctioning system could trigger the 17519/P1111 code.

  2. Poor Electrical Connection: Loose or corroded electrical connections between the ECM and other components can disrupt proper communication and cause this fault code to appear.

  3. Sensor Malfunction: The presence of faulty sensors associated with the engine torque monitoring can lead to the triggering of the 17519/P1111 DTC code.

Diagnosing and Resolving the Issue

Addressing the 17519/P1111 DTC code requires a systematic approach to diagnose and rectify the underlying problem. Here are the steps you can take to resolve the issue:

  1. Perform a Visual Inspection: Start by conducting a visual inspection of the engine compartment and look for any loose connections, damaged wires, or faulty sensors. If you spot any issues, address them accordingly.

  2. Check Electrical Connections: Ensure that all electrical connections related to the ECM and torque monitoring system are secure. Clean any corroded connectors and reconnect them properly.

  3. Test the Sensors: Test the sensors associated with the engine torque monitoring system. Use appropriate diagnostic tools to verify their functionality. If any sensor is found to be faulty, it may need to be replaced.

  4. Resetting the Code: After addressing the root cause, reset the DTC code using a compatible diagnostic tool. This will clear the code from the ECM’s memory and turn off the check engine light.

Frequently Asked Questions

To provide you with further clarity, here are three frequently asked questions regarding the 17519/P1111 DTC code:

Q1: Can I continue driving my vehicle with the 17519/P1111 DTC code?

A1: It is generally safe to continue driving your vehicle with this fault code. However, it’s important to get it diagnosed and fixed as soon as possible to prevent potential complications in the long run.

Q2: Can a faulty Oxygen (O2) sensor trigger the 17519/P1111 DTC code?

A2: No, a faulty Oxygen (O2) sensor is not directly related to the 17519/P1111 fault code. This code primarily indicates an issue with the Engine Torque Monitoring Control.

Q3: Can a DIY enthusiast fix the issue related to the 17519/P1111 DTC code?

A3: While basic troubleshooting steps can be performed by a DIY enthusiast, it is recommended to consult a professional mechanic or technician for a precise diagnosis and thorough resolution of the fault code.


In summary, the 17519/P1111 DTC code refers to a fault within the Engine Torque Monitoring Control. By understanding its potential causes and following a systematic diagnostic approach, you can successfully resolve the issue. Remember to address loose connections, faulty sensors, and reset the code using the appropriate diagnostic tools. Seeking professional assistance is recommended for a comprehensive diagnosis and repair of the underlying issue.
