When you see the Engine Light ON or the Service Engine Soon Warning Light, it could be indicating a fault code of p1288.

This code specifically relates to the engine coolant temperature sensor.

The sensor is responsible for monitoring the temperature of the engine coolant and sending this information to the engine control module. When the p1288 fault code appears, it means that there is a problem with the engine coolant temperature sensor circuit. This could be due to a faulty sensor, a wiring issue, or a problem with the engine control module itself.

It is important to address this issue promptly as it can affect the engine’s performance and potentially lead to overheating. To fix the p1288 fault code, the first step is to inspect the wiring and connections related to the engine coolant temperature sensor.

If any damage or corrosion is found, it should be repaired or replaced.

If the wiring is in good condition, the next step is to test the sensor itself. If it is found to be faulty, it will need to be replaced. Finally, if the sensor and wiring are both functioning properly, the engine control module may need to be diagnosed and repaired.

It is recommended to consult a professional mechanic to accurately diagnose and fix the p1288 fault code.
