Turbo Thermostat Housing Sensors.

[bassline21 1]

hello. i can remember reading somewhere but unfortunately forgotten where that i only need the blue sensor on the thermostat housing for my turbo conversion?? is the green one something to do with the 406s original air conditioning sytem?? and the brown one?? cheers

green is for the ecu, blue for the dash gauge+warning light, brown for the cooling fan control system on aircon models.

which will i use to power my rad fans then mate? using the forum without being in my garage fills my head questions lol sorry

 

 

[bassline21 1]

also while your here. i knoiw its off topic. but if i get hold of an early xm ecu. (ending in 219) can i just do away with the keypad imo? thanks again

[welshpug 1,662]

you dont use any of the engine sensors for the cooling fans when its in the 205, its all self contained.

 

as for the early ecu, depends if they had immobilisers of any kind, easy enough to sort yours out though, just fire it up and disconnect the keypad afaik.

Neither. You use the 205 fan wiring.

thats my problem i havent got the main harness and keypad. could get one as theres a 406 fresh in my local breakers but i believe the early citroen xm ecus are non imo type. so if i use one of these im hoping i can just bin cables 821,820 and 822. cheers for the answers so i just wire my fans up on original circuit and take the blue sensor to the instrument cluster. lovely job

As far as I know

i have 2 ecu's ending in 219, one from an xm and one from i think a xantia and both only needed a live to a certain pin for them to work, both didnt have keypads iirc. (iirc = if i remember correctly) what do the 406 ecu's end in as i might have a favour to ask you as mines overfueling and iv changed everything sensor wise bar my ecu (map sensor).

[bassline21 1]

the part number for mine is 0 261 200 813. ask away mate??

[jonnyturbo 3]

if you could get me a price on the ecu and knock sensor please there the only 2 which iv not really changed although i do have 2 ecu's both could be bust.

[bassline21 1]

you want a price for the ecu and knock sensor from the breakers? or my ecu? go to silverlakes breakerss on google. search the 406s in the breakers section. take the ref number for the blue executive turbo and ring them. theyll post. are you interested in selling one of your 219s?? if you can test one id be interested in swapping ecus if you are? cheers

I doubt if the loom for the 219 and 813 ecu's are identical.... Maybe worth checking before you buy a 219 ecu (without loom)?

[bassline21 1]

ecu and knock sensor is 60 pounds for the pair. thats taking it off the car from the public yard. so your probably looking at 80 for them to take them off and deliver.

[jonnyturbo 3]

id happily sell you one but like i said im not sure if the map sensor is broke or not as mine is overfueling from cold, they do work as in when put a perm live to them though. I could send you one out and if it works you could paypal me after if you want? your therfore helping me as well by proving to me its not the ecu that is causing the overfueling.

[bassline21 1]

yes that would be sound ill pm you my details. how much will you want for one? also do you want me to send my 406 ecu so you can try this on yours??

[jonnyturbo 3]

nah dont worry about sending yours, im pritty sure nothing is wrong with the ecu's i have and it is something else but my car isnt going anywhere anytime soon so il wait to see if your car runs ok or not.
