Peugeot 407 engine fan Start late at 114°c !
Hi, I need your help please,
I have a Peugeot 407 2006 year, 2.0 RFJ engine code, IAW 6LPB ECU, HW 9659580780, SW 9662982980.
The problem is the engine fan Start late at 114°c, no fault of fan in memory of ecu, there is fault of electric thermostat (P0597) but the engine without electric thermostat.
Is the problem of flash ecu?
someone have a ori file?
Thanks in advance.

Hi
Thanks for your answer, the fan works well with the A / C and When I test the actuators, fan function normally, when it starts at 114°C starting on full speed.
There is no configuration for the fan activation in ecu.

Hi,look the archive,like say vish check if the fan operate at fisrt velocity,if not check the
wiring diagram.I think the electric termostat don´t operate as well.

Note:
For vehicles with a plug connection
On the thermostat housing, the following OE parts (Certus)
For the amendment:
1x 1343KZ = hose
1x 6582GW = plug connection
1x 6980A7 = holding strap
Should the error P0597 be read out
The additional cable 9678362080 must be installed.

there is no electric thermostat and thread from ecu (pin 4H_ con 32V MR) to electric thermostat (pin 2).
I shall install a new thermostat and raccording to the ecu or
change the dump of ecu.

Fan begins to spin if the temp sensors reads wrong temp!
You should change both the temp sensor and the thermostat!

RE: 407 engine fan Start late at 114°c !
first check what type of fan do you have on this car..they have few version..some with aditional controler build in fan motor ..some with aditional wire resistor and relays..looks to me that you have only ..let we say ..emergency fan blowing ..when engine ecu think something is realy wrong..so check can you start actuator test some slow speed of fan..maybe in configuration you have few options for fan types and somebody choos wrong..

its french so many MAYBE involved always...

good luck
