The PO128 code in your Honda Civic indicates that the coolant thermostat temperature is not reaching the ideal level for efficient operation. Possible reasons for this could include a malfunctioning or stuck thermostat, a faulty coolant temperature sensor, or a radiator fan that remains constantly on. The most probable culprit is the thermostat, which is the component most mechanics would recommend replacing if you encounter this error code. The thermostat is inexpensive and easily accessible, making it a straightforward solution that typically resolves the issue. When installing a new thermostat, it's also advisable to flush the engine block and radiator to prevent any particles or debris from adhering to the new component.
