faulty plugs can throw an O2 code. also, i wouldn't worry too much about damage to the catalytic convertor. where i live, the worry is more from people cutting them off!
The ML320 was a rig made for guys/gals that like to turn wrenches. it’s surprisingly pretty user friendly from a mechanical standpoint. I love my W163.
They're not bad to work on - only got rid of this one since it was a vehicle a family member had to rely on and started popping up with electrical gremlins that I didn't have the time to diagnose and fix and that would've been cost-prohibitive otherwise. Thanks for watching!
I couldn't figure out the connector. The o2 wire ended up having loops when installed again cus I couldn't take out the connector. lol I'll try again. Thanks.
Hi, my 99 320ML has an issue that I have to restart the engine every mile or so. Before it was a few times on a 100 mile trip but now all the time. Driving slow is a bit better, its worse with more power. What do you think? The obd said misfire on all cylinders. I do have a little problem with the headgasket but only a very minor water leakage. Thanks, great video!
That could easily be related to the headgasket, too much water into the cylinders, fouling out plugs, clogging cats, lots of potential issues coming from water leakage and a bad headgasket. Thanks for watching!
@@explorinlearnindoing5462 2 liters is definitely something to be concerned about, but I've seen much worse. Definitely due for replacement of those gaskets or the engine as a whole.
yes, when truck is at operating temp, it can stall and you get turn over no start. YES O2 sensor. ( I bought a cheap scanner on amazon ..25 buks. IT came up right away with this exact problem I have. Fixing tis week will post again.)
@@crewtheaftermath4105 It can certainly create a no start condition, but if your scanner points to other sensors I'd investigate those before replacing arbitrarily. If you have a live data readout on the scanner, that would help diagnose what's going on with each sensor. Thanks for watching!
@@redonKiLaus HI Thank you. Yes it is my sensors and one code for secondary air injection system. But that system works, So I thin it is Just myO2 sensors which is great, But one more question, Can I use o2 Bypass on All o2 sensors? Mainly ask as next year I need new catz and will be using after market ones, SO it would be nice to get ahead of this. If I can bypass All banks that would be amazing. ( lol and cheap!)
@@crewtheaftermath4105 You can't bypass all O2 sensors, just post-cat ones and only on some vehicles. Pre-cat ones control your air fuel ratio, bypassing will make your vehicle run poorly.
I have an American Mercedes ML 320 1998 it has a problem and I do not know why ! sometimes, cylinder nr 4 - 5 -6 stop work .And sometimes are working I went to mechanic shop several times and can not find a result .spark plug are new . The mechanic opened this side of engine and checked everything , and the car still with the same problem . can you advice me plz ?
Is there a diagram I can get? I get p156 sensor circuit bank 2 sensor 2 error on my ML 320 1998. But I don't know wich sensor I need to replace? Can you link me to an image? Thank you.
You just need to figure out which side of the engine is bank 1 and 2, once you do that you're just replacing the post-catalytic converter sensor on that side. It varies by manufacturer, and I can't remember Mercedes' nomenclature off the top of my head. Thanks for watching!
The sensor that detects that is the second one down, not sure if bank 2 is driver or passenger side though. That said, you may have a bad cat and not a bad sensor with that code. Thanks for watching!
Hi, thanks for the video. Im getting codes for o2 sensors so I changed all four of them. I used my Reader to clear the codes and take off check engine, however after driving for about 20 minutes the codes came back. The codes I’m getting are p0130(o2 sensor circuit bank 1 sensor 1), p0135 sensor heater circuit bank 1 sensor 1) and the same For bank 2 sensor 2. I am also getting another code which is p0400(exhaust gas recirculation flow) ... does p0400 have anything to do with the reason why o2 sensor codes have t erased even after I changed all four of them? Thanks again for your video and your insight
The EGR code could potentially affect the initialization of O2 sensors, but from your description it sounds like you have a clogged or leaking EGR system (not uncommon on these) as well as potentially a wiring problem with the O2 sensors if they were all replaced with the correct parts. Definitely would require some poking around to diagnose past that. Thanks for watching!
Generally not, unless your vehicle is running terrifically rich due to the bad O2 sensor, generally white smoke, especially if consistent, is a headgasket issue. Thanks for watching!
Ok, let's just make clear for me please. I have ML320 1998. If I have a code P0156 o2 sensor circuit Bank 2 sensor 2, it means it's driver's side downstream sensor with round ending after converter, right?
@@redonKiLaus thanks,if my obd 2 scanner code said cylinder 5 and random cylinder misfire which oxygen sensor would i replace and could it fix misfiring issue?and i did hear there is a lambda controller and a lambda sensor as if seperate by someone on some website(not by a certified mechanic).
@@charlesthompson1935 The O2 sensor may or not be related, but it would be one of the ones (likely primary) on the side that cylinder is located on. The ECU reads from the sensors, there is no separate controller that I'm aware of.
@@redonKiLaus your right even a another mechanic said there was only oxygen sensors(i misread code on obd 2 scanner) , i think my coil packs and plug wires are the problem ,thanks!.

have the same issue, could be eléctric failure?. did u fix it? How?
@@redonKiLaus I will appreciate if u could help me to.
check the catalyzer, i have the same problem and was an obstruction of it.. we replace it and works fine.
I had the same: the tip of the coil pack caused issue-try used on or above these particular spark plugs or change yours around on these to rule out.

Hi I have a 07 gl450 and got code p0432 main catalyst efficiency below threshold (bank 2) would this be the first one or 2nd one down? Thank you.

In the title why did you skip ml430
So the video wasn’t much informative upon how to remove it
I did actually figure it out and is not really hard if you have the right tool
