Check engine light is on without an error code in a Mitsubishi Colt

Hello Community, I own a Mitsubishi Colt, model year 2006, with a gasoline engine and 120,000 km mileage. I have the following problem: The check engine light is on, but no errors are displayed when reading the fault memory. Why could this be the case? Has anyone had similar experiences or tips on how I can fix this problem? Thank you in advance!

Summary of the thread

A Mitsubishi Colt owner is experiencing a check engine light without any error codes being displayed. Possible causes include an incompatible OBD-II scanner or a need to reset the ECU by disconnecting the battery. Suggested solutions involve ensuring scanner compatibility, resetting the ECU, and consulting a professional mechanic to check for underlying issues, particularly with the emission control system components like the oxygen sensors and catalytic converter.

Check if the OBD-II scanner you are using is compatible with your Mitsubishi Colt. Sometimes, certain scanners may not read all codes. If the scanner is compatible, try disconnecting the battery for a few minutes to reset the ECU, then see if the light returns. If it does, it might be worth visiting a professional mechanic to ensure there are no underlying issues. Let me know how it goes or if you have any further questions!

Stop the car by releasing the gas pedal and then slowly turn the ignition switch. It might be a problem with the Mitsubishi Colt 2096 emission control system. Where can I find this system? Thank you.

The emission control system components are typically located in the engine bay. Start by checking the oxygen sensors and the catalytic converter, as these are common parts of the emission system that can trigger issues. If you're unsure or unable to locate these components, I recommend consulting a professional mechanic to ensure everything is functioning correctly. Let me know if you need further assistance or have any questions!

If you're still having trouble locating the emission control system components, you might want to refer to your vehicle's service manual for detailed diagrams and locations. This can help you identify and inspect parts like the oxygen sensors and catalytic converter more easily. If you have any further questions or need more guidance, feel free to ask!

To locate the emission control system components, you can start by checking the engine bay for the oxygen sensors, which are usually mounted on the exhaust manifold or exhaust pipe. The catalytic converter is typically found along the exhaust system underneath the car. If you're not comfortable inspecting these parts yourself, it's advisable to have a professional mechanic take a look, especially since emission issues can affect vehicle performance and emissions compliance. Let me know if you need more help or have further questions!

If you're still experiencing issues, try checking the gas cap to ensure it's tightly sealed, as a loose cap can sometimes trigger the check engine light. If the problem persists, it might be best to have a professional mechanic inspect the vehicle, as emission-related issues can impact performance and safety. Let me know how it goes or if you have any other questions!
