I’ve seen the titles of his vids but never watched them .. the titles read goofy to me . I decided to check one out today and hey not bad at all .. funny everyone else seems to already know this guy hahaha .. Old Scotty must have beamed you up early ..

He's definitely a character all his own. From what I've watched of him he seems to know what he's doing he's just very forthright and shares exactly how he sees it and why

I’m confused or not at what I’m finding about O2 sensors ..
We know we have 2 up stream and 2 down stream sensors on the truck !
I’m reading info about them and shopping for them and finding that some say they are different and not interchangeable. At the same time shopping for the sensors they don’t differentiate at all .
So what the heck is the difference here if so or are they actually the same sensors in all 4 locations ???
Only asking about the Standard replacements and not the performance ones .

 

[rottenronnie]

2 different part numbers
Front and Rear.

 

[VIPR PWR]

Even with different part numbers I can find the differences from up or downstream sensors .. actually I’m finding more than 2 part numbers showing compatibility ! I’ve seen searching n a few that the only difference is the color f the connector with the same pin configuration and a couple with a different looking tip end . I see sets of all 4 that all appear to be the same and do not state which are upstream or downstream .
All appear to have the same functions , specs and send the signal to the controller .
The only thing I can think of is they are all the same except maybe there is a difference in the wire length ..

Other than that I am at a loss of what to buy or not . Prices vary a lot . These would be for my 2002 Dakota and 3.9. Which I get the 0051 code and appears to be the bank 2 sensor 1 is possibly bad . I read it is recommended to replace them in sets ..

Are they still available through Mopar?
The difference is very likely wire length and/or the connector design. Obviously they all measure Oxygen content (in a fairly narrow range of one volt or so).
Wideband sensors (for tuning) have a range of around 5v and are considerably more expensive.

 

[VIPR PWR]

I read about the performance O2’s and those are considered the Wideband… Heck sounds to me with the emissions crap required Widebands should have been required by the Government EPA .. shhh don’t tell them hahaha they are expensive compared to the retail aftermarket standard O2’s .. I look at a MOPAR PARTS WEBSITE can’t remember which site .. But the standard sensors were around $137 each . That’s as usual for Mopar parts A RIP OFF ! I found after market sets and single sensors everywhere .. A set of 4 in one case was $57 .. and I think the cheapest single sensor was $18 ..
I won’t spend a lot for anything on the old work truck Dakota but definitely need to verify that these O2 sensors are not actually different which I’m not finding verification..
if they are 1 volt , screw in the bung and the connectors match along with proper length wires then I see no difference between the up stream and the down stream sensors .. I looked at the Dakota sensors on both sides , they look identical and are not that far apart from each other .. which makes me think the ones I looking at on websites are all the same and interchangeable..
As for the 10’s I haven’t looked into those . The ones Ive looked at appear to fit other motors also !

this is a good thread! Any questions??

 

[VIPR PWR]

Yes it is and anyone can ask and answer questions ,

So in the past week or so, when I fire up the truck, sometimes I hear a strange whistling sound. It comes and goes when I accelerate, or just idling. It's not everyday, and when it does happen, I'm usually driving to work. Seems to only happen when the engine is cold started. It goes away as she gets warmer. Anybody have an idea what it might be?

Sounds like a possible vacuum leak , but odd it comes and goes ..
Maybe a slipping belt or belt tensioner pulley..
try using a stethoscope or a pipe to listing through and try to pin point where it is ..
just keep it away from moving parts ,, that can hurt bad !

So it's not the belt or tensioner, I've eliminated those two. I'm leaning towards a vac leak as you say, but like I said, unable to pin point is as it's sporadic.

You can try a can of carb cleaner and spray sparingly light controlled squirts around vacuum hoses and intake bolts/ gasket area .. it f the rpm’s change then you find the vacuum leak .. I had a leak at the cruise control which has a vacuum hose to it .. the hose was split causing a vacuum leak at. Easy fix .. My hose to the valve cover ventilation had a hole in it and I had to fix it also .. I goes from under the throttle body to the valve cover on the but has a steal pipe between hose connections.. mine was at the valve cover .. had to find a hose that would work and did at advance auto and use screw clamps on on side as the Inside diameters were different.. somewhere on here is a pic and post of that fix .

Oh ,, and CAUTION , CARB CLEANER IS Flammable !

I had a similar noise. It turned out to be the seal on the throttle shaft was leaking

So when I jumped in the truck to go home from work, it made the same noise. I popped the hood, and it's not a vac leak. The noise is either coming from the power steering pump, or whatever is mounted under the pump, (AC?). I turned the AC on, was blowing cold like it should. And as usual, once the temp got to around the first temp mark, it quit. Ideas?

Smit load enough to record the sound ?
Try a little wd40 on the belt when the noise is happening and see if that quits it down !
Is the Power steering reservoir filled to level ?
My guess is what ever it is quiets down as the heat expands something!
Since you live in a southern state couls it just be whistling Dixie lol.
I hate trying to find elusive noises it’s almost as bad as looking for electrical problems..

 

[VIPR PWR]

On my Dakota .. I a plug change and replaced PCV valve .. after a couple weeks I started hearing a whistle grinds noise in the engine area . Thought it was the belt adjustment idler pulley bearings . So I replaced it and the belt .. Didn’t stop the noise .. only did it on Idle when vacuum was highest and stopped hitting the throttle.. finally I started really looking around and lo and behold .. It was the PVC valve .. I replace it and it stopped for another few weeks and started again ,,, I have tried another PVC valve and just let it ride as is .. no idea why they keep doing that ..

 

[VIPR PWR]

What’s under the PW pump ? Isn’t the AC on the opposite side of the engine ? ( I haven’t looked at mine , yet lol ) ..

 

[VIPR PWR]

I would still try the stethoscope tool to try to pinpoint or narrow it down .. just be real careful putting it near moving engine part !
