This guy here is a prime example of what America is supposed to be - HONEST - EFFICIENT - CLEAR & CONCISE - THOROUGH - ACCURATE - UPBEAT - HELPFUL!!!!!!!!!! THANKS FOR HELPING ME KEEP MY CAR SAFE AND QUICK ON THE ROAD!!!!!
Thank you bro, very easy to understand your explanation. I just installed a new catalytic converter to have a p2423 code pop back up.
Yeah change that sensor also will take care of it!
@@RBTheMechanic thank you sir
Great explanation
So can you use Carb cleaner?
I wouldn’t use that use catalytic cleaner
Hello sir h r u? I m SYED RIZVI.you remember i often asked with u a good tip for my Honda.
Hey mate thanks for the video but I need to discuss very rare scenario with you.
I got mitsubishi outlander 2017.
So I changed the spark plugs and then , I didn't start the car and remove the air intake housing in order to clean my throttle body with throttle body cleaner, I had to remove the connector on top the assembly, I guess it was MAF sensor connector, so then I asked my friend to start the car but , car start and dies straight away , I thought I unplug the sensor therefore ECU not getting right readings and causing car to not start, then I start again and then forcefully let the acceleration go and rev the car like 4 min on 4000 rpm until my friend finish the can cleaning the throttle body but then we put the plug back and car still start and die straight away, then I lift the car and checked that cat convertor is like red hot , and then I realised that while changing spark plugs, I messed up and swap the wires between two spark plugs.
And today my car engine light turned on and the code I got is P0421 saying warm up catalyst Efficiency below threshold Bank 1.
You think I damaged my cat already , or o2 sensors.
What should I do now?
Can I still drive a car until I fix it?.
Thanks Mate.
Wow u guys went way out of boundaries never rev the engine like that to 4000 rpm usually 1500 is acceptable .... ok so what happned it u guys messed up firing order so I burned fuel ended up burning in catalytic converter on top high rpm on top injected cleaner spray so u over worked and maybe damaged the catalytic how ever u didn’t get p0420 code so. I would do this clean the oxygen sensors if that don’t work then replace the oxygen sensors before changing out the catalytic converter reset the light and then drive and see what outcome u get if code don’t return u should be good also keep and eye on the catalytic so it’s not cherry red hot
@@RBTheMechanic i am currently looking to live data on obd reader,
My o2 sensor 1 fluctuating between 0.1 v to 0.7v but it drops to 0.1 v again and again but o2 sensor 2 fluctuating between 0.5 v to 0.7 v and not droping to 0.1 v .
O2 sensors Should drop to 0.1 v isn't?
Thanks for the prompt reply bro,
Much appreciated.
so can I drive the car until I organise o2 sensors?
Thanks again
@@SahilSharma-uc6dz I guess so keep an eye on the catalytic converter usually if it got burnt it will not have good flow and it will get hot quick and turn red
@@SahilSharma-uc6dz I can’t make a judgement on that I would need to check with my scan tool and compair the data and know the values
Thanks brah. Helpful video
need an advice for in a matter related to my car.
I have a Honda Accord 2017 EXL (174500 miles)
I got to change the catalytic converter (after markert autozone) for about 5 times in 3 years. Recently i changed it two 3 days ago and drove it 150 miles till now. Once i changed the upstream sensor and never change the downstream sensor too.but this time i cleaned both sensor with CRC spray.
I just posted this video 4 days ago how to get car inspected that’s not ready or getting ready here’s the video th-cam.com/video/miP4tVovJXc/w-d-xo.html
What kind of sea foam is using? Is it carburetor cleaner?
U can use carb cleaner parts cleaner even maf clean works
Which do you think would be best? I have all three on hand. Thx. You rock!
Thanks brotha
But the problem is Emmision is not still ready for the inspection. I am due for the inspection but this problem is making me insane.i m Uber driver in NYC.I have to pass my inspection.
Can you please help me out in this regard and advice me a better solution?
Not ready means u need to drive the car drive it for a good 100 miles
But i already drove 150 miles.what u think that after market converter is worth or not????
@@syedrizvi8488 well watch the video I drove over 200 miles after market converter is ok I use walker brand
@@RBTheMechanic hi just drove almost 200 miles on the highway.i check with obd scanner,but still converter is not ready to inspect.i drove 65 to 75 speed.still the prob not resolve.
@@syedrizvi8488 u have to keep driving… I hope ur not resting if ur getting check engine it has to be drive cylicle keep driving I had customer who drove 700 miles then the system got ready there’s no other way even if u replace it u will go through same process
you can not clean an o2 ......period
I have done it
You destroy the zirconia element when you do that.research it
@@sleathers1551 that’s internal I’m not braking it open only cleaning off build up
I had multiple codes a few were the o2 sensors an other was the catalytic converter along with a few others, I explained to the service man when I originally did the code tests the code for the o2 sensor came up he started giving me a whole lot of mumbo jumbo and said I’ll take care of it. Called me next day said he replaced 2 sensors some gas sensor and another I never heard of and while replacing one he broke a piece and had to replace that also cost 770 that’s hundred, said drive car about 100 miles engine light should stay of if not come back after 30 miles engine light came on took it back he tested codes said ya that’s what I thought u need a catalytic converter wasn’t even going to try the up and down stream o2 sensors said 900 for cat and that should do it, told him to screw took car to another place said I wanted both 02 sensors replaced he offered to clean then figured he was pretty cool offering me that option but said maybe please replace worked great he said last resort is changing the catalytic found your info helpful and subscribed
