Outside Temperature Gauge

[Brian73]

Recently had my car serviced and it has come back with a couple of errors. Firstly the outside temperature on the screen just comes up as -- . Been quoted a ridiculous amount to replace sensor , is it an easy job to do myself ?. I've read the sensor is in front of radiator and have to take front grill off to access it.
Thanks for any advice.

Removing the bumper is a 10 minute job. There’s some good YouTube videos on it.

The sensor is straight forward.
$40-$50 unplugs. Plug in new one.
