Answer 1

The P0125 code in a 1997 Mercury Villager indicates that the engine is not reaching the required coolant temperature for efficient operation. This code typically points to issues with the engine coolant temperature sensor, a faulty thermostat, or problems with the engine's cooling system. As a result, the vehicle may experience poor fuel economy and increased emissions. It's important to diagnose and address the underlying cause to ensure proper engine performance.
