Q: What does code P0217 mean?

Engine Over-Temperature Condition. P0217 means the powertrain control module (PCM) has determined the engine coolant temperature has exceeded a calibrated safety threshold, typically around 250°F (121°C) or higher depending on the vehicle. The PCM sets this code when the coolant temperature sensor signal stays above that limit long enough to confirm a genuine over-temperature event rather than a transient spike.
