I have tried everything, but I am coming to the conclusion that I have a bad pcv letting in too much air. The concensus of how to fix it seems to be to clean the MAF with some electical cleaner or brake cleaner. Basically, you are getting too much air into the throttle body after the MAF or a dirty MAF.

    One more thing:

    Go to and put in year, make and model and then navigate to "Trouble codes", look for the number you received and the site will explain what you are looking at.

My 2003 kia sedona won't pass emissions the codes are p0320 p0431. Help please

code p 0320 refers to crankshaft position(CKP) sensor /engine speed ( RPM) sensor ---circuit malfunction===causes --wiring---CKP/RPM sensor---ECM
code p 04310 refers to warm up catalytic converter, bank 2--efficiency below threshold===causes ---cat converter---wiring---HO2S 2
As it is not passing the smog test I would be replacing the HO2S sensor ( manifold or before the cat on bank 2 of the engine ) or more likely a failed cat converter
you may have had the P 0320 code for a long time and have not noticed a drop in performance but as cat converters have a lot to do with smog control , that is the area I would advise checking first

Have a2004 Kia Sedona with p0431 code. What is it and is it costly to repair

I'm not a tech but the code states:
Warm up catalyst efficiency below threshold.
This is dealing with the catalytic converter. Yes these type of repairs can be costly, but worth it to get quite a few more years out of your van.

Kia p0431, p0446, p0715

They are three separate issues.
Code 431 involves the O2 sensors and the catalytic converter, code 446 is for the evap vent control for the gas tank, and code 715 is for the input shaft speed sensor in the transaxle.
The engine temp and other factors would need to be checked for code 431, and the sensors would need to be tested for the other two codes.

I ran an engine analyst and got codes P0446 twice and code P0431 once. what does this mean.

P0431 Warm up catalytic converter, bank 2 - efficiency below threshold
Possible causes: Catalytic converter, wiring, HO2S 2

Usually caused by worn out catalytic converter, but always check fuel pressure regulator for proper operation before replacing a converter.

P0446 Evaporative emission (EVAP) system, vent control -circuit malfunction
Possible causes: Wiring, EVAP canister purge valve, ECM

May be caused by a loose or disconnected wire to the vent valve or possibly a bad valve solenoid

If you would like part locations, troubleshooting or replacement procedures, please let me know.

My 2004 Kia Sedona's engine light is constantly on. A mechanic attached a diagnostic tool and came up with the following codes: P0431 and P0325. Anything to be concerned about? Thanks

P0325 Knock sensor (KS) 1 , bank 1 - circuit malfunction
Possible causes: Wiring, poor connection, KS

knock sensor malfunction may reduce fuel mileage due to computer reducing ignition timing advance.

To repair: Check connector on knock sensor. If connection is good, replace sensor.

P0431 Warm up catalytic converter, bank 2 - efficiency below threshold
Possible causes: Catalytic converter, wiring, HO2S 2

increased HC emissions--no effect on engine performance unless caused by rich mixture.

To repair: Usually caused by worn out converter, but first verify fuel pressure regulator is not leaking fuel into it's vacuum port and that fuel pressure at the fuel rail is not above specification.

The car will run fine and there are no safety issues; however, before driving over anything that could ignite (for example, grass), make sure the catalytic converter is not glowing red.

If you have more questions, please let me know.

Engine codes p1159,p0431,and p0122.what are they ?how can i fix?

P0431 code on audi allroad 02

Typcally caused by one of the front oxygen sensors or a bad ground associated with these sensors.Replace both front sensors with direct fit type NOT universal, because there may be a cracked wire and the universal sensor does not contain the complete wire harness. Direct fits, are about $20 more than universal fit type.

The O2 sensors have integrated heating elements that bring them up to the proper operating temperature. Code P0431 indicates that the O2 sensor on your driver side catalytic converter is not reaching the proper operating range. The O2 sensors are usually in the $150 range online.
