I didn't know the answer to your question, but I did some research, and this is what I found:

Is your battery light on also?
On cars with no battery blanket sensor, the AIT sensor acts as both air intake temp, and ambient temp. When mine was unplugged, I got a battery light. The alternator will still charge, but at a fixed 13 volts, or something close to that.
P1193 is temp circuit low voltage. Not sure what the correlation is to actual sensed temperature, if it is low temp, your alternator may be putting out too high of a voltage for the ambient temps. Too high, it may be lower, or it has defaulted to the 13 volts.
If you have a voltmeter, I would check to see where it is. 14.5 volts won't really hurt much, unless the temps there get very hot. If the battery is good, it shouldn't go much over 15ish volts anyways. You would know if it was going higher. Your headlights would have excellent output
