P1258 Code: Easy Steps to Solve It
The P1258 trouble code is a diagnostic trouble code (DTC) that indicates an engine coolant overtemperature condition. Specifically, this code is triggered when the Powertrain Control Module (PCM) detects that the engine coolant temperature has exceeded a critical threshold, typically around 132°C (270°F), for an extended period. When this occurs, the PCM activates a protective mode to prevent engine damage by disabling fuel injectors in
