Hi everyone

I have a Honda Civic 2007. My onboard thermometer (which gives a digital reading like the image below) is not giving correct readings. It either gives a reading much below the actual temperature or gives nothing at all, only dashes! How do I fix this? Any ideas?

I'm thinking about checking, and possibly replacing, the sensor but where is it located? Thank you for any help.

The ambient temperature sensor can be seen through the front bumper grille below the front number plate.

Your varied temperature readings does sound like a faulty sensor, but I would also check that there is no corrosion on the sensor connector as well.

I could replace the sensor, it does more than tell you ambient air temp.
It acts like a choke to modern cars.

It tells the ECU what baseline to use for fuel for the current air temp on start up

Sorry to hijack the thread - But I've noticed mine takes a little while to get to the "Correct" temperature (according to the weather), it normally starts off at around 7/8c, but then eventually makes it's way to, for instance, 2c (the actual temperature), is this normal?

Thank you all very much. I plan to check it next weekend. I hope it won't rain (Urg... UK weather).

Killgroup,
I wish I could help you but I don't really know, although Grayfox's reply should suffice.

I know this is an old thread, but just in case anyone else has this come up, I have just replaced mine, bought the part from DHGate.com for $16 from China with free delivery, delivered in 2 weeks and with a long thin screwdriver (to release the little clips) and a pair of long nose pliers was able to get the old part off, and the new one on in 20 mins without removing the bumper, was a bit fiddly but relatively easy to do and as opposed to it saying it is 55C in the snow it is now showing a more reasonable 3C and I have cabin temperature control again, happy days.

Just thought this may help
