I have a 306 1.8 16 valve petrol. About 5-10 secs after startup the radiator fans are coming on and staying on. The aircon is off. There are no other indications of a fault. I've measured the three sensors at the left side of the engine block (one above the other on pipe near battery) and all three have a cold resistance of about 1k ohm. Anyone with knowledge of this? Does anyone know where the fault diagnostic output plug is?
