    Default Fan sensor

    Hello all, I recently had my car in to a local mechanic who found that my coolant leak was due to a broken fan sensor. He has since replaced this but now my thermo fan is on whenever the ignition is on no matter how cold the engine. He then said it needs to go to Peugeot to be calibrated, is there any truth in this or is it just a faulty sensor??

    The thermofans in the 406 have a failsafe mode whereby if the sensor goes open circuit, or there is a break in the wiring, they will default to high speed.

    Either you have a dodgy sensor, the sensor is unplugged, or the wiring has been damaged somewhere.

    There is no calibration required, I suggest you find a new mechanic.

    you know the story

    'mate it can only be the car, the part is a new one straight out of the box so it will be fine'

    the typical it's foreign and i don't want to understand or look any further

    if the fans were going off their nut before then i'd say the sensor is kaput and he needs to replace it with another one

    Thanks very much.

    I come from a Honda back-ground in terms of my knowledge. (1990 CRX, and had pulled the aircon out anyways!!)
    And I didn't think a temp sensor would need to be calibrated!

    Might go to the local Peugeot dealer (who I chose to use wholly and solely now) get them to diagnose my problem, and then take a run down of the issue and bill to him. (WHat a damned hassle...)
