Angry 1224 check engine code for 1994 325I

I flunked emissions today with HC reading of 276 (124 std)
co% of 4.36 (.69 std)
I found a web sight which told me how to check the check engine code wich has been blinking on and off for a while and just yesterday went full on. The code is 1224 which they say is intake air temp sensor. I do whatever repairs I can on my own cars and could really use some help on this one.

This code is stored when a short to plus or a break in the
wiring at the Intake Air Temperature Sensor or its supply wires
exists. Check the value of the sensor. 2.2-2.7 KOhms at 20C,
760-910 Ohms at 50C

Would this bad sensor cause the high HC and CO%?

Unhappy 1994 325I check engine code 1222

I originally had a code 1224 (air inlet temp sensor) the car flunked inspection with high HC and CO. I found the air inlet temp sensor loose, and after tightening I went through inspection OK. Now I have code 1222. What is this code for a 1994 325I BMW 6 cylindar?

This code is stored when the DME detects excessive
deviations in the air-fuel mixture (too rich or too lean) for longer than 10 seconds. Possible causes: Fuel tank ran empty,
Incorrect Fuel Pressure, Injector valve defective or coked,
Engine Temperature Sensor defective, Secondary air leak,
Fuel evaporation control system defective, Air Flow Meter
defective and/or the combustion is being disturbed by
mechanical failure (Spark plugs,, compression,
intake/exhaust valves, ...etc.)
