Default Outside temperature reading wrong??

hi

just finished fitting a turbo back exhaust system and drove the car home off boost and realised the outdoor temp is wrong, says 30 degrees lol

i must have knocked it while fitting.

where would this be? how could i sort it ? could i have knocked it?

IIRC it's just behind the front bumper - Clipped to the metal support bar, between the bonnet catch and the lower crossmember. - You should be able to see it through the large aperture in the front bumper

The system uses an algorithm to determine if the temperature its reading is right, as it gets heat soak from the rad, so if you had a 'funny' drive cycle it could be due to that.

You could have bent it round until its touching the rad, in which case it will definately read wrong!

ok guys i cant find what is up with it, there is no chance it has moved its fixed tight!

could the sensor have gone?

i just dont get why it has gone faulty straight after fitting the downpipe..

could i have done something when moving the lambda over the gearbox? as i saw some other wires there

Does it have a removable electrical connection? If so the first thing I'd do is unplug it/firmly plug it back in and make good the connection again. You never know...

well,it depends on how much the sensor is thats near the plate,if its like £20 id start there,but if its like £60 then you need to diagnose 110% etc

but i cant see there being too much to replace parts wise either the sensor or the reader/display if its a built in decoder blah blah etc
