To find out what code 341 *means* for your specific 1994 Ford Explorer, you'll need to:
1. Consult a 1994 Ford Explorer repair manual: These manuals contain detailed diagnostic trouble code charts specific to that year and model. They'll translate the code (if it's valid for your vehicle) into a meaningful description of the problem.
2. Use a Ford-specific OBD-I scan tool: Some older scan tools are capable of reading the codes from a 1994 Explorer's OBD-I system. These tools will likely provide a more understandable description than a generic OBD-II scanner.
Without more information, it's impossible to say what "341" represents. It's possible it's a misreading of a different code, a code from a non-Ford system, or a custom code assigned by a mechanic.
