A Car Engine Code Scanner, also known as an OBD2 scanner, is an essential tool for diagnosing car problems. When your check engine light comes on, a code reader can quickly identify the issue, saving you time and money on potentially costly repairs. AutoZone offers a wide variety of car engine code scanners to help you get to the root of your vehicle’s problem.
How a Car Engine Code Scanner Works
A car engine code scanner works by accessing your car’s On-Board Diagnostics (OBD) system. The OBD system continuously monitors various engine sensors, including temperature, fuel, and oxygen sensors. This data is fed to the engine computer, which analyzes it to detect any malfunctions. When a problem is detected, the computer generates a Diagnostic Trouble Code (DTC) and illuminates the check engine light.
Using a car engine code scanner, you can retrieve these DTCs and understand what they mean. Each code corresponds to a specific problem, allowing you to pinpoint the source of the issue. This information can be used to troubleshoot the problem yourself or to provide valuable information to a mechanic.
