Detecting engine faults before they cause major problems can prevent losses, accidents, and headaches. Today, with the help of artificial intelligence, there are powerful apps that perform this diagnosis quickly, safely, and intelligently, directly from your phone. Below, you'll find five apps available for Android and iOS that use AI to identify faults in the engine and other automotive systems. You can download them below.

Car Scanner ELM OBD2

The ELM OBD2 Car Scanner is one of the most popular automotive diagnostic apps. It uses artificial intelligence to interpret data received from the vehicle's control module (ECU) via OBD2 (On-Board Diagnostics) devices.

The main advantage is the user-friendly interface, with detailed graphics and clearly explained fault codes. Furthermore, the app's AI learns from fault patterns and suggests probable causes, helping the user or mechanic make faster decisions.

The app displays real-time data such as engine speed, temperature, fuel pressure, and even emission levels. Its performance is excellent even on entry-level smartphones, and fault detection is quite accurate.

OBD Auto Doctor

OBD Auto Doctor turns your smartphone into a professional automotive diagnostic center. Compatible with most OBD2-enabled vehicles, the app uses artificial intelligence algorithms to identify faults and provide comprehensive reports.

The AI performs an in-depth analysis of engine parameters and detects anomalies even before the car displays a warning light on the dashboard. A key differentiator is that the app offers detailed explanations of error codes and possible solutions.

The user experience is very intuitive, with organized menus and a modern look. It also allows you to save previous diagnostics, useful for monitoring engine health over time. Performance is fast and accurate.

Torque Pro (OBD 2 & Car)

Torque Pro is an advanced vehicle diagnostic tool that stands out for its robust and customizable features. It uses sensors and an OBD2 connection to capture engine data and apply artificial intelligence analysis.

It's ideal for advanced users, as it allows you to create custom dashboards and monitor hundreds of parameters in real time. The app's AI learns from the vehicle's behavior, providing alerts about potential failures that haven't yet generated error codes.

Torque Pro also integrates GPS to cross-reference performance data with location, and provides comparative graphs of engine performance over time. The user experience may be a bit more technical, but it's excellent for those seeking in-depth analysis.

FIXD: Car Health Monitor

FIXD is designed for drivers who want to keep their cars in good condition without needing to be an expert. By connecting a FIXD OBD2 sensor to the car, the app communicates with the vehicle's electronic control unit and uses artificial intelligence to identify problems.

Its strength is its simplicity: error codes are translated into clear language, such as "Oxygen sensor problem" or "Ignition system failure." Furthermore, the app shows the severity of the problem and whether it's safe to continue driving.

With AI, FIXD also provides maintenance predictions based on vehicle usage, as well as suggesting preventative actions. Usability is excellent, the look is clean, and performance is consistent. Perfect for the average driver who wants to avoid surprises.

OBDeleven

OBDeleven is a comprehensive diagnostic and programming solution for Volkswagen Group vehicles (VW, Audi, Seat, and Skoda). It uses artificial intelligence to analyze engine and electronic system failures, with advanced capabilities that go beyond traditional diagnostics.

In addition to identifying errors, the app allows you to run system tests, reset sensors, and even program new functions in the car. AI helps suggest useful adaptations based on usage history and driver profile.

The interface is modern and responsive, with quick access to information. Ideal for those who want complete control over their car's operation, without relying on repair shops for basic diagnostic and configuration tasks.

Featured Features

The apps mentioned offer a range of features that transform your phone into a true automotive monitoring center. Some of the most common and useful features include:

• Reading and interpreting fault codes (DTCs)
• Real-time sensor monitoring (RPM, temperature, pressure, etc.)
• AI-powered smart alerts
• Diagnostic history and reports
• Preventive maintenance suggestions
• Detailed graphs and visualizations
• Customizable dashboards
• Clear explanations for laymen
• Reset error light on dashboard
• Compatibility with most OBD2 vehicles

Each app targets different audiences: some are geared towards everyday users who want simplicity, while others offer more depth for enthusiasts and mechanics.

Conclusion

With the help of artificial intelligence, it's become much easier to monitor your car's engine health, detect faults before they cause serious problems, and even save on repair shop diagnostics. The apps presented in this article transform any smartphone into a powerful, practical, and reliable vehicle diagnostic tool.

Whether you're a regular driver seeking safety or a specialist seeking advanced data, there's an ideal option among the available apps. With features like intelligent fault detection, maintenance predictions, and clear error interpretation, taking care of your car has never been easier.
