search online using code. it OBD 2 and standard code for vehicles

Sounds like faulty O2 sensor or bad wiring to it

P0030: P0030 HO2S Heater Control Circuit B1S1

P2237: P2237 O2 Sensor Positive Current Control Circuit Open Bank 1 Sensor 1

Have the following checked for proper operation: Mass Airflow sensor (its located on the air filter box), oxygen sensors. If ok, I would recommend having the wires checked for possible damage from rodents biting on them.

I have a 2005 Kia Spectra. The check engine light has been on and i got it checked. What does engine codes P0030 and P2237 mean?

CODE P2237 HO2S 11 PUMPING CURRENT CONTROL CIRCUIT OPEN BANK 1 SENSOR 1 POSSIBLE CAUSES. POOR CONNECTION OR DAMAGED HARNESS, OPEN IN HO2S CONTROL CIRCUIT, FAULTY HO2S,THE ECM HAS FAILED.

P2237 P2196 P2271 P0030 P0171

These are all O2 sensor trouble codes, except P0171 which is a fuel trim code,

You have a bad 02 sensor - up stream - Bank 1 Sensor 1.

Replace it, then road test. The engine computer has a 'default' fuel trim it uses when an O2 sensor fails so it can protect the catalytic converter. If this hasn't been going on too long, good chance simply replacing the O2 sensor will remedy your problem.

Yes it could but i would suggest checking the crank position sensor as it will not throw check engine codes. Also go to an auto store and have them pull the codes for you for free.
