B-1 1-2-2 = Outside air temperature sensor failed. No big deal, really, but it will turn off the automatic part of the ECC. You can still work the fan and air direction manually, but I would first clear the code before looking for a replacement sensor.

To clear the code, read the code twice in a row. Just keep pushing the black button until you get the same code. Then push the button down for 5 - 7 seconds, release, and push again for 5 - 7 seconds. The red light will respond both times. Wait 10 seconds, then push the button again. If the 1-2-2 comes up again, the sensor needs to be replaced or the plug to the sensor needs to be cleaned.

The sensor is located at the top of the cabin air intake duct, passenger side, under the windshield and in the engine compartment. A couple of T30? screws to lift the cover. Check for a cabin filter while you are there, if no filter then go to FCPGroton and order a couple of filters and a filter holder to keep dirt out of the system.

PS. Use the code reader boxes to go through all of the A & B ports and clear any codes that come up every time you change your synthetic engine oil. B-2 will show a 1-2-2 that will not clear which is just fine.
