These codes cover 3 different areas. Misfires, cam sensors and transmission issues. I would suggest taking the vehicle to a good mechanic so they can look at it in more detail.
The Codes mean...
P0300 = Random/multiple misfires detected.
P0302 = Cylinder 2 Misfire detected.
P0344 = Camshaft Position sensor Circuit intermittent.
P0700 = Transmission control system malfunction.
I means that the vehicle failed it's emissions test as it failed the digital trouble code reading test 3
the testing station tests the exhaust emissions and the onboard computer
Your computer failed the test
That is a speed sensor "a" low input code. Sometimes the sensors are external and sometimes they are internal. I don't remember specifically for your vehicle.
I would suggest monitoring the sensor with a higher end scan tool capable of reading transmission data.
Cylinder 2 Misfire Detected po302 . Evaporative Emission Control System po440 The last digit on a misfire code indicates the cylinder number. A code P0302, for example, would tell you cylinder #2 is misfiring. Chances are the misfire is due to a weak ignition coil. Did you change the pcv valve? Remember to put the o-ring on the new one or this problem will happen.
P0404 Exhaust Gas Recirculation Circuit Range/Performance P0502 Vehicle Speed Sensor Low Input P0440 Evaporative Emission Control System Malfunction
hope that helps /a little beyond my expertise but theres your codes your looking for ;)
Something unspecified is wrong with the evaporative emission system. Check vac lines. Could be a loose electrical connection. This code has a very vague description.
P0302- Cyl 2 misfire
Has the car had a tune up in the past few years? Check plugs and wires, test for spark. Maybe a compression test. This issue may cause the next code.
P0172- Fuel trim Bank 1 , too rich
I would clear up the misfire first, then this code might go away.
P1613- MIL Call-up circuit open/Short to B+
Check the wiring under & behind the dash and instrument cluster. There apparently is a wiring issue, or the dash itself is shorted

16686/P0302/000770 - Cylinder 2 Misfire Detected Possible Causes
Ignition system
Fuel injectors
Fuel pressure
Running out of fuel
EVAP canister purge valve
Evaporative emission system
Low compression
Base engine problems
Controle Module damaged
Special Notes
This feature search for engine misfire in a specific cylinder.
Most of the time the cause for a misfire is a lack of combustion in a
cylinder due to absence of spark, poor fuel metering, or poor
compression.
