Hi guys and gals, my AC temp readout always says - 86 i think its the

ambient temp. Anyway fitted another fan thingy in the pod in roof

cause i didnt have one hoping it would sort it. Any idea if and where

any other sensors are or any idea what the problem is.

cheers

my car never had that fan when i had it, i bought from a member here, and cant honestly say its any different, so i doubt the fan is to blame mate

bubbles, your ambient air temp sensor is disconnected or failed, it is located behind the bumper, replace or reconnect and it will read the correct air temp then.

There is a temperature sensor out somewhere.

I think the first one to check is the ambient temperature sensor which is behind the front bumper, (you wont need to take it off) it should be on the drivers side just to the outside of the numberplate. I have had to replace that one due to shouwing -86 and I got the sensor from the main dealers at a cost of about £37.

Hope this helps

Cheers guys, will have a look and hopefully sort it.

ey up bubbles, just put a new senser on your old car and it hasnt made a diff. the senser works as ive tried it on si-z car.

 

anyone any ideas on how to fix this problem?

thanks in advance

might be a fault in the pod itself then, tried swapping that? If that still doesnt work then i'd say a wiring problem.

ta for the reply, whats the pod, is it that black can?

i know nowt by the way, only had the zed for 2 weeks and its my first one!!

i think it knows what im thinking and i am scared!!

nah that black can by the sensor is the carbon canister i think. What I mean is the control pod for the a/c in the cabin

yeah si had the pod off today and had a quick look, seems ok nothing obvious, you mean swap that, the unit with the controls on?

if that doesnt work is wiring the only other thing it could be? anything else i could look for?

nice colour btw

yeah try swapping it. If it doesnt make a difference then you have ruled out the electronics and the sensor so it must be the wire connecting them.

theres a diagnostic you can do that brings up codes for o/c s/c sensors and actuators. better to try that first rather than randomly change out things that you dont understand.

ive looked at the diagnostic in the online manual and i cant understand that either, i ran it for the laugh and just got more confused!!

well, stick at it, theres obviously something gone bottom scale (most probably still the ambient sensor or some associated wiring. so the Climate controler is trying to tell you something.

 

that diagnostic was developed because its a complicated system, some one has spent a lot of time designing it so it must be there for a reason, if it was simple to fix then it wouldnt be there ;)

yeah, the amb temp is reading -89 so i presume its along that line somewhere, is the diagnostic any more specific than the readout on the amb temp guage? like will it tell me which link in the chain has gone? as the prev posts say maybe in the wiring, ill try si-z pod, hook it up to my connectors, if its still the same ill beg some more advice..

cheers guys

its most probably an RTD try bridging the connector with a100ohm resistor it should read 0 that will tell you the wiring is ok ..go to each end with the resistor and se if you get a reading ...my guess is a open circuit in the wiring ..could be a bad corroded connection clean them all up and see what happens especially at the sensor end

from memory the coloured rings on the resistor should brown black black from left to right ..

aye only if its a PT100 tho and not some dodgy oddball RTD. try getting someone with a working one and measuring it. and comparing the resistance to urs or find a resistor with the same resistance and frig it to see if itl read.

not sure what youre onabaat but it sounds like good advice....can that be the case?

it can in my mind and thats all that matters :wack:

once the dodgy ambient temp sensers been swapped for the new one does it need reseting, like the ECU does once a fualty parts been replaced. ie: by disconecting the battery for a couple of hours.

anyone help?
