External Temperature reading... Faulty!

[anonymous1]

Hi,

Just another quick one.

The external temp that shows on the OBC display continuously reads -37 and I'm just wondering if this will be affecting anything or if it is it's done by a separate sensore to the normal one? It's been like this since I bought the vehicle, but only just started wondering if it could be affecting anything else.

Thanks in advance.

I believe the OBC sensor is only used for the OBC...

Look under your front bumper. There is a small hole next to the left fog light, and behind that small hole is your temp sensor. See if it is either disconnected, or maybe has a cut wire. It is fairly straightforward and easy to fix.

The sensor is for the ambient temp display only and won't effect anything else. -37 indicates an open circuit, usually at the connector to the sensor from corrosion.

pretty sure that the AC will not kick on if the exterior temp reading is below a certain level - someone want to correct me if I'm wrong?

I heard that Michigan winters are a bitch.

Hi,

Thanks for the input on ths one. The temp sensor is now fixed, to a certain degree (No pun intended). Had a look and the wire had snapped at the point where it meets the connector block on the sensor itself. Had to cut away the rubber on the connector block to the sensor and then used more connector blocks to splice the wires back together. Only issue now is there isn't enough wire for it to go back were it was, so instead it's cable tied to the side of the engine and reads hotter than it prob should. (Least I never remember a 30oC winter in sunny old UK)! But at least the OBC doesn't beep at even turn of the key now to tell me I have a remote chance of dying from minus -37oC temp.

Thanks again.

Good job. Wire is cheap, and it shouldn't take much to get the sensor back in its home.

Isn't this where the temp is read for the AC compressor and/or the heated mirrors?
