Bank 2 catalytic converter

The second, or the bank 2, catalytic converter, I believe I was told is rattling and causing the check engine light to come on. I'm trying to shop for it online and am seeing "right" and "left." Any idea which I need?

SOURCE: heat shield rattles

I wouldn't recommend removing it, as it's there to protect the area from the high heat of the cat. I've had the same rattle problem, and a piece of a coat hanger through a couple of holes drilled through the shield, then tightly attached solved the problem.

SOURCE: do I need a catalytic converter

Yes, depending on how bad the converter is. The converter can fall apart inside and all the pieces will then move to the muffler plugging the muffler. The result will be a plugged exhaust system. You can check to see if the exhaust is plugged by putting your hand in front of tail pipe and "feel" how much is coming out. Have someone "rev" the engine and you should be able to feel the exhaust from 2 to 3 feet away. Just so you know what normal is, do this with a different car first. If it's plugged you'll be able to tell. Good luck. Hope this helps.

SOURCE: 2000 Cavalier catalytic converter was stolen/check engine light

The check engine light is probably indicating a catalytic converter malfunction the Oxygen sensor that is located after the cat tells the computer if the cat is functioning properly it is possible the wire has been broken or damaged. To see if the cat is there jack up the car and look under the passenger and driver area of the car follow the exhaust pipe from the front back the first thing the pipe comes to should be the cat it looks like a muffler with a wire going to a sensor after toward the back side of it, I doubt they never installed one but I guess it is possible.

What does code PO431 mean on 03 Kia XL. My check engine light is on. Auto zone said I needed to replace Catalytic Converter(s). Does anyone know how many Catalytic Converters are on it?


code p 0431 refers to warm up catalytic converter, bank 2--efficiency below threshold === causes ---cat converter---wiring---HO2S sensor 2
it should be a v6 engine as it has 2 banks , bank 2 is the one closest to the grill.
there should be 2 cat converters ( one for each bank)
from the suggested causes , I suspect that the HO2S sensor is not performing properly and is not providing the correct mixture to the cat converter to make it operate properly
if you bump the cat converter with the hand and it rattles , it will need replacing and autozone would be right
However I am always of the opinion that you should seek other advice from an accredited exhaust specialist shop and get a quote as cat converters are not cheap

Where is the 02 Oxygen Sensor before the cadalic converter on a 2006 Hyundai Santa Fe


Usually these are located on the exhaust manifold or just below the exhaust manifold and you should be able to see it in the engine bay. On V6 engines there will be one sensor on each of the 2 exhaust banks.
You will probably need to remove the engine cover to see the sensors on your exhaust.

If someone told you to replace these because you got a particular fault code I would be wary. A decent scan tool and basic diagnostics can show if the 02 sensor is working or not. Some faults often blamed on an 02 sensor are not due to faulty sensors.

Catalytic Converter Replacement Repair Cost


code p0420 refers to catalytic converter system bank 1 --efficiency below threshold ===causes -- catalytic converter ---wiring---HO2S 2 sensor
The cheapest part to replace is the HO22S sensor so I would do that first. Bump the cat converter soundly with the heal of your hand and if it rattles it needs replacing as it will be cracked internally. Dismiss any tinny rattle as that will be the heat shield loose
The time taken to replace both in an accredited shop will be less than 1 hour so it may pay to shop around and compare prices on the converter and labour costs.

2003 Highlander CE light, scan codes P0420 and P0430. DO the appearance of both 0420 and 0430 indicate that problem is most likely the Catalytic converter? Or might it still be a problem with either or...


code p0420-430 refers to both cat converters (bank 1 and bank 2)--efficiency below threshold== cause cat converter- wiring --- Ho2s. As cat converters are subject to cracking and failing and thereby not doing the job I would suggest having them checked and replaced if necessary. A local exhaust shop should be able to do the job . If they are cracked/broken there will be a rattling sound when the exterior is hit

Need to replace bank 2 sensor 2 on 2003 toyota highlander , where is it located


Bank 2, sensor 2 is a heated O2 sensor located below (after) the catalytic converter on the passenger-side. When this sensor gets clogged and/or goes bad from rust and heat fatigue, the voltage drops low enough to cause the electronic control module to register error code P0161, which then causes the check engine light to come on.

To replace Bank 2, sensor 2, remove the debri shield from just behind the front bumper, underneath the vehicle. There will be 10 bolts holding it on (10mm, I believe). After removing it, look toward the center of the newly exposed area and you will see 2 finger-like objects projecting out from the engine with wires coming out of each. The one on the left (passenger-side) is bank 2, sensor 2. The one on the right (driver-side) is bank 1, sensor 2.

I got my direct-fit sensor online for $55 from Remart Auto Parts. I know it is tempting to get the universal-fit type and save the cash. But after doing that once, I wouldn't care to do it again.

I found a YouTube video showing pictures of where the two lower (after catalytic converter) sensors are located. While the video only points out the driver-side sensor (bank 1, sensor 2), it's easy to spot the other one being only inches away.

Catalytic converters


If you are going to change the convertors I would just replace the first one closest to the engine. But when a computer code says "bank" they usually are refuring to the Oxygen sensor that is there , they are classified as bank 1 and bank 2. 1 being closest to the engine and 2 being farther down the exhaust. If its a computer code that told you bank 1 you might need to look at your oxygen sensor instead of your catalitic converter.
