getting to the bottom of why my coolant fan doesnt come on on my 2003 206 hdi 2L turbo multiplex
first i have had the codes read and came back with
>------P0115 engine collant temp signal -----<
P0100 flow sensor signal ie: maf
P0101 air mass sensor circuit maf again
P0571 brake contact signal
now the symptoms are as follows the car temp gauge stays at 75% - 90% once warmed up i have left it sitting at idle for 20 mins and still the fan doesnt switch on
going to check fan wiring for continuity earth was ok after a quick check with multimeter
maxi fuse in engine fuse box , direct connection fan to battery
thermosat is in housing
now my question is the engine block temp sensor is of the resitance type ? so if i disconnect if the temp dial should zero and if i bridge the sensor plug the fan should come on ? not sure because its ecu controlled
any help on this would be good

Just unplug the coolant temp sensor on the thermostat housing, this will bring on the cooling fan.

Shut it u stupid little f**k, what's the point in posting in all my treads being such a c***? Least I can afford a gti180, and to get the cam belt done!

So apparently everyone knows my financial situation? If I wanted a 180 I would have bought a 180 simples Smile

thanks LeeThr i unplugged the sensor (after putting the fusebox back ) the preheat light came on with key in position 2 started the car and 2 seconds after the fan came on so i think the sensor is faulty never thought to unplug the sensor
