According to the chrysler "tech connect" tech. help website, P0073 is Ambient air temp sensor high. Likely cause is the sensor itself.

Engine light is on with the code p0071 and p0073 and it coincides with outside temperature indicator. It fails all the time showing me weird temps this morning I've found the sensor hanging out.

You should replace the sensor and re-attach it properly. The engine ECM uses outside air temperature to adjust the fuel mapping on an engine. The codes you have are for the fuel to air ratio which has everything to do with the fuel mapping of an engine. Hope this helps

How to fix 2006 jeep wrangler p0073

Code 73 means the signal coming from the air temp sensor is too high. Could be the sensor or a short in the wiring.
You may need a shop manual to get the testing procedures.

What do the codes p0072 and p0073 mean on my 2008 Dodge avenger? w

Well, I would say that it means that SOMEBODY is confused!

Diagnostic Test Code (DTC) P0072 is defined by SAE J2012 as "Ambient Air Temperature Sensor Circuit Low" DTC P0073 is defined as "Ambient Air Temperature Sensor Circuit High"

I do not know how the ambient air temperature sensor circuit could be faulted both HIGH and LOW at the same time.

The only thing I have ever seen cause something like this is when people try to install aftermarket "performance chips" on their vehicles which "lie" to the computer about what the ambient air temperature is.

P0073 is actually for the "Ambient air temp sensor high" which is likely to be the sensor itself, or possibly the wiring for it.

you will need to test the unit with an Ohm meter (disconnected from the wiring harness, engine OFF) at different temperatures to see if you get a good reading on it.
