What has to be fixed on a 2009 volvo v50 when error code P420 appears?


P0420 is catalyst efficiency below threshold. It means your catalytic converter is unable to clean up your exhaust anymore. Might be that your car is not running properly and creating excess emissions, or it might just be a bad cat. To do this properly, you need a scan tool that will give you live data. Your must check fuel trim, must be no misfires You will need to make sure you are not burning oil, consuming coolant, or having any other driveability issues. At that point and only at that point if the code still persists you should replace the catalytic converter. If you replace the catalytic converter and the engine is running poorly, the new converter will fail right away.

Error code 2005 vw beetle -P2096


code p 2096 refers to post cat converter fuel trim(FT) bank 1 ---too lean===causes --cat converter---exhaust leak
it also refers to heated oxygen sensor (HO2S) 1 bank 1--range/ performance --circuit high====causes --wiring short to positive ---HO2S
replace the HO2S using the correct socket so the wires do not get damaged
for the first one check for an exhaust leak in the flex section of the exhaust pipe under the steel mesh

Error Code P0430


this is the o2 sensor after the pre cat so post cat you can get a tune to get rid of code or replace the o2 sensor or get spacer that screws into the cat witch will make it not code the o2 sensor is there to just make sure the cat is there for emissions and will not effect the gas milage

Volkswagen touareg 2005, V6, 3.2L error code P0420, P0430 and P0068


Hi. Please concentrate on fixing p0068. this is to do with airflow and fuel/ mixture. maybe air mass meter. these can cause faults p0420 and 0430 to come on. after p0068 is repaired clear all faults and take the car on a long drive to clean out the cats, reassess if the cats are actually faulty at a later date.

My engine light was on, so i got a diagnostics done and it said the bank1 sensor 2 needed to be replaced. i Replaced the sensor but the engine light keeps coming back on after the part was replaced and...


no year. stated, sigh, nor country, sigh 2.
no DTC posted.!
post the DTC code, do not interpret it , state it. P0xxx?
flat out.
are there other codes? other stored or pending DTC codes?
(errors)
there are many oxy codes, not stating the code is bad news.
each has a different reason, guessing is a fail.

btw , sensor 2 does not run the cars fuel mix. that be sensor 1.
btw, sensor 2, is rear of cat sensors.
this sensors purpose IS TO , warn of a dead CAT.

if the CAT is getting NAILED by rich fuel , the cat can be good
and the code P042x is one, that can be cause by other fueling issues. RICH. if rich (vastly) the cat can overheat. and fail that test. you need to post all facts, in my questions. first.

Po430 error code what is it


Code 430 is for a problem with the catalytic converter on bank two.
It means the computer can not tell if the cat is working or not based on the readings from the O2 sensors.
The sensors and the cat would need to be tested.

Error code P0430 rear catlytic converter where exactly is this located and what does it look like and estimated price?


just a word of advice there is no sensor that tells you if you need a cat ! that code comes on because of faulty o2 sensors have you changed the 02 sensors yet ? if not change them reset ( clear ) the codes that code will come on a few times just keep resetting or clearing it i have had 2 co workers not listen to me and changed the cat 400-600 dollars and the code just comes back on one guy had the cat changed two times and the code came back after i reset the codes 3 times it stayed off it seems like its preset to come on around 100,000 miles with 02 sensor codes DONT LET THE MECHANIC SELL YOU A CAT hope this helps

Code p0420


Hello.

Normally, the P-0420 indicates a sensor issue; a cat replacement would be needed if you had the P-0420 coupled WITH a
P-0430 code.

What I would do, if I were you, would take the car to a shop that can perform an "induction cleaning", and have that service done. Then, replace the spark plugs, if the car is around 90,000 miles. You may alsop need a front air-fuel sensor (the one on the manifold) replacement.

I would not change the cat until I did the above services. It does not sound like a bad cat just yet.
