FORD FIX CODE P0420 CATALYST SYSTEM EFFICIENCY ANY FORD
If you have Ford, your engine light is on and you have code P0420 in this video we will explain what often causes code P0420 and how to fix it. Code P0420 is very common for high mileage Ford cars and any car pretty much. The code stand for P0420 Catalyst System Efficiency Below Threshold Bank 1. We will explain the most common causes of the code based on our experience at the garage but it could be multiple causes for that code. We demonstrated what causes engine light and code P0420 on Ford Focus but it will work on multiple models:
Ford Focus Code P0420 Engine Light On
Ford Fiesta Code P0420 Engine Light On
Ford Mustang Code P0420 Engine Light On
Ford Flex Code P0420 Engine Light On
Ford Edge Code P0420 Engine Light On
Ford Escape Code P0420 Engine Light On
Ford Explorer Code P0420 Engine Light On
Ford Fusion Code P0420 Engine Light On
Ford Taurus Code P0420 Engine Light On
Ford F150 Code P0420 Engine Light On
Ford Expedition Code P0420 Engine Light On

Son's fiesta1.0 140ps displayed p0420 on cheap diy machine, followed videos, called ford specialists, ford's, confirmed new cat. Great not cheap on theses cars. We took the car for other work to a recommended garage and they tested with their diag kit. With their kit it indicated sensor no 1 had intermittent fault...which didn't display sensor fault on the diy machine....

[@briansimpson5041]

I recently changed the Titanium stock airbox to a RS airbox and changed to a K&N filter, would this toss the code due to air fuel ratio?

sorry to say but i want see how to exchange sensor (practice) with hints, not only show by screwdriver , that there is sensor, this i know, I expect little bit more details

How much is expensive for a catalytic converter change

[@benjaminalexander5504]

Hey mate. I was wondering if you could help me. I have a Holden Cruze 2009 1.8L petrol. It’s throwing rich codes ( p0172 ). I’ve checked ( oxygen sensor, coolant temp sensor, MAF sensor, map sensor, spark plugs, fuel ingectors, and purge valve ) they are all reading well to my understanding, and I’ve used all you videos to diagnose them. But after checking all of that it’s still throwing rich codes, has extremely bad mileage, and smells of unburnt fuel. It is also hesitating from take off and hesitates a little at idle. I am studying to be a mechanic in Australia but I’m not quite there and I am verry lost with this car. I would really appreciate the smallest bit of help. PS- your videos are really good and have helped me so much

[@juniormorales559]

Yes guys thank you guys p0420 guys yes guys ford guys good introduction guys like video guys😝😂

[@charliecross2]

I've got this code and changed the O2 sensors with no luck. I'm thinking it's the catalytic converter also hear a "ticking" on idle which I've heard is a bad cat. The exhaust manifold and catalytic converter are one assembly for anyone else out there. What's confusing is, looking at the schematic there appears to be a second catalytic converter assembly after the second O2. Not sure if I need to change this one also and how would it throw a code with no sensor behind it?

[@keithpatterson1196]

Do you have a code reader that will show you live stats of vehicle systems?

[@charliecross2]

@@keithpatterson1196 I do not could be a good investment

[@keithpatterson1196]

I got a Bluetooth one for about $100 and it tells me the voltage at both my O² sensors. But it sounds like you already changed them. Sorry for the late reply.

[@akinraankh1489]

Does Cataclean help with cleaner the o2 sensors and catalytic converter?

[@harryramsey8651]

I wouldn't rely on it for the O2 sensor, it may help if it is dirty but in most cases just general wear and tear (hot gases) ruins the sensor so it can be cheaper to just replace it.

[@juniormorales559]

My situation was the previous owner never changed the spark plugs mine was at 105k when it threw the p0420 codes someome told me that misfires and stuff which i was having would damage the catalytic converters i put some spacers on the o2 sensors so far so good.

@@Stratic I just put the spacers I did clean the cats a little blew them out alot of dust came out they looked good its just cars nowadays are so sensitive catalytic converters should honestly last you the lifespan of the vehicle I have a 2002 expedition with 200k miles has never gave me catalytic issues just try cleaning it and add the spacers I heard you can even wash them and dry them out or try looking for an alternate catalytic converter that's if you dont live in a state like California the cat that was giving me issues I found a non oem one on ebay for about $170.

Hi, I’m getting P0420 I used the adapter on my o2 sensor and I’m still getting the P0420 code what could the problem be?? :(

[@Raddy_N]

Catalytic converter

[@CharlesLease-ei1ee]

You have to read the data and figure it out automotive is not 123 snap your fingers and it’s fixed. You have to know the values what your fuel trims are supposed to be what your air fuel mixture is there’s a lot of things it causes code, misfire, vacuum leak, fuel pump, coolant, temperature, switch mass air, a wiring problem problem, running, lean, running rich transmission overheating over temp exhaust leak open circuit to your O2 sensors. You can have an internal problem with your motor. A lot of people think oh I have a scanner. Well I’m gonna put it to you this way a real technician should be able to plug that scanner in and not open the hood and diagnose that vehicle as long as you have the correct scanner with a lab scope function testing and knowledge and know what the values are supposed to be and I have seen this done. I didn’t believe it until I seen it.

[@jkenney940]

Did you use it on the upstream or down steam O2 sensor?

[@RainorShine1]

I have o0430 😥

I have a 4 cylinder and have P0420 and the diagnostic tool says bank 1. Which 02 sensor do I need to change?

[@danthonythegreat3140]

If you're asking this, you didn't listen to the full video.

[@sgtketchup]

you will need to replace the upstream O2 sensor

[@Dr650rob]

Bank 1 = cylinder 1

[@jdhshuajfjueudhbd6227]

Nope, bank 1 and bank 2 indicate the left and right sides of the engine. In the case of an inline motor there will only be bank 1 codes, while a v motor will have both.@@Dr650rob

Guys!

[@AP-mf4fz]

I've read that removing the catalytic will actually help horse power and not affect the engine in any way is this true?

[@justin456]

On a really old car yes, on a newer car with up and downstream O2 sensors no, removing the cat will make the car run like garbage.

[@holleyciggy]

@@justin456 not necessarily

[@justin456]

@@holleyciggy Nothing is worth speaking an absolutes but as far as pure mechanically yes removing a restriction from the exhaust stream would certainly help to reduce back pressure. Once fuel trim values get effected that theory goes out the window.

[@brandonhooker4498]

Only if the vehicle is tuned properly after removing the catalytic system. They're tuned from the factory to include those systems so if you remove them it will need to be re-tuned.
