Trouble code P1281 typically indicates an issue with the engine coolant temperature sensor or its circuit, often related to overheating or incorrect readings. To fix it, start by checking the coolant level and the condition of the coolant; replenish or replace it if necessary. Then, inspect the coolant temperature sensor and its wiring for damage or corrosion, replacing the sensor if needed. Finally, clear the trouble code and monitor the vehicle to ensure the issue does not return.
