* Engine codes are vehicle-specific: Engine codes are unique to each vehicle make and model year. A code 126155 on one vehicle might mean something entirely different on another.
* Diagnostic tools needed: To understand an engine code, you need a specialized tool like an OBD-II scanner. These tools connect to your vehicle's computer and can retrieve the code along with a description of the potential issue.
To figure out what engine code 126155 means, you will need to do the following:
1. Use an OBD-II scanner: Get a scanner from an auto parts store or online.
2. Connect the scanner to your vehicle: Follow the instructions for your specific scanner.
3. Retrieve the code: The scanner will display the code and its description.
4. Research the code: Use a repair manual or online resources to find information about the specific code and how to address it.
Important Note: If you are not comfortable working with vehicle diagnostics, it is best to take your Grand Caravan to a qualified mechanic. They will have the proper tools and expertise to diagnose and repair the issue.
