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

P0431 warm up catalyst efficiency below thereshhold bank 2

What does that mean? Basically this means that the oxygen sensor downstream of the catalytic converter on bank 2 is detecting that the converter is not working as efficiently as it should be (according to specs). It is part of the vehicle emissions system. Symptoms You will likely not notice any drivability problems, although there may be symptoms such as a rough/hard idle when cold. Causes A code P0431 may mean that one or more of the following has happened: The catalytic converter is no longer functioning properly An oxygen sensor is not reading (functioning) properly There is an exhaust leak Possible Solutions Inspect for exhaust leaks. Next step is to measure the voltage at the oxygen sensor on Bank 2. In fact, it would be a good idea to test each oxygen O2 sensor while you're at it. One thing to note is that many vehicle manufacturers offer a longer warranty on emissions-related parts. So if you have a newer car but it's out of it's bumper-to-bumper warranty, there still may be warranty on this type of problem. Many manufacturers give a five year, unlimited mileage warranty on these items. It's worth checking into.

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.

My 2004 sedona has little power going up hills, my local machanic says the code( po431) means the bank 2 catyletic converter is bad, but which converter is bank2? also have a code -p01159 which no one...

The answer to your first question is the Oxygen sensor bank 2. Its the oxygen sensor after the catalytic towards the rear of the motor. For the other DTC there is no P01159 DTC, P0159 is Bank 1 Sensor 1 Oxygen Sensor bad, P1159 is an air intake leak or a MAF (Mass Air Flow Sensor leak)

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.
