after market O2 sensor ??
 

My 1988 260e is failing the emissions test and people tell me that its' probably a bad oxygen sensor. New ones (bosch) go for anywhere from $170.00 to $116.00, but I found an aftermarket one (walker) for $39.95. (thats right, only $39.95..) Does anyone have any experience with these ? Is there a way to check those out to see if its' bad ? Thanks.

Do a Google search for "O2 Sensor Mustang Mercedes"

The BOSCH O2 sensor for a Ford Mustang can be spliced in (using the MB connectors) and it will only cost between $38-$50. I've done this previously and it works.

My experience has been that the more sophisticated the diagnostic ability of the ECU , the less chance of using a Universal sensor without tripping fault codes.
The full EFI and SFI units watch the 02 sensor parameters much closer than the early units .
And from OBD2 on, OEM seems to be best.....

Here is a link to the article I found a few days ago...

I have a 92 190E2.6. When my O2 sensor started acting up, I replaced it with a Bosch sensor (pn#13953) for a Ford Mustang 302. I Just cut off the ford sensor connectors and soldered my old MB sensor connectors on with heatshrink tubing. Works great and only about $40 at Autozone.

The MB Bosch O2 sensor and the Ford Mustang Bosch O2 sensor are the same, just different plugs. Its criminal really, $120+ price difference just for a plastic plug. The same sensor is used on many other applications as well. Did this on my 190 with no problems at all

2phast,

Will that O2 sensor also work on my 1999, C280?

That would be great.

Thanks,

Jeff

Unfortunately the 1990 Ford Mustang 302 will not work, since it is 3-wire O2-sensor. The W124 6-cylinder's used a 3-wire O2-sensor, your W202's use a 4-wire O2-sensor.

I have purchased a Chrysler Voyager 3.6L 4-wire BOSCH O2-sensor, but haven't spliced it into my C36 engine (it too uses the 4-wire O2 sensor), but it might be worth the try at only $45 vs. $170+ for a MB 4-wire O2-sensor.

You beat me to the answer Neil!

Go to oxygensensors.com or global4autoparts.com Both have generic and substitute o2 sensors that should work. I bought mine from global4autoparts. I am using a NTK o2 sensor which, I think last longer than the Bosch IMO in my 400E.

<<I am using a NTK o2 sensor which, I think last longer than the Bosch IMO in my 400E.>>

I have done some scope comparisons between NTK and Bosch 4 wire [ heated] sensors and actually found the NTK to be both faster [ higher cross-count] and a cleaner signal....
Test was done on same vehicle/ecu set-up for accuracy.

Will this Ford sensor work on my 89 420 sel? What year ford mustang?

Neil,
Please give me the BOSCH part number for the Voyager 3.6L 4 wire Oxygen sensor.

Thank you.

BOSCH 13275

Thank you
 

Thank you Neil.

According to BOSCH Oxygen sensor application book, that Chrysler van is a Plymouth-Voyager/Dodge-Caravan 89-95 with L4-2.5L engines, V6-3.0L engines and V6-3.3L engines.

Next, I would appreciate it if any of the listers would look up the torque value for an Oxygen sensor on a 1992 600 SEL.

Best regards. :D

Re: Thank you
 

Torque is 55 Nm. And you need to use hot lubricating paste on the thread.
Mike

No need to use the paste with the MB specific Bosch sensor. New in the box, it comes with the high temp anti-seize paste already applied. Perhaps the Bosch units for the Chrysler do too???

A good copper-based anti-seize also works.

I use LubroMoly's.

:-) neil

There is some A/S already on the threads.
 

The Bosch sensors I bought today, came with some anti seize on the threads.
I can not tell what base it is, just by looking at it. It looks grayish, so maybe it is graphite based but I really can't tell.
I may put an extra dap of copper based A/S just for good measure.

Thanks to all of you.

Sorry to bring back an old thread, but my car (95 e320) uses 4 wire sensor. I was given a bosch part number 13314. Can I use the voyager oxygen sensor instead of the mercedes one? It seems like bosch part number for that one is 13275.

Thanks for the clarification and if anyone has done this to their late w124s please drop me a line.

Thanks

The gray stuff is probably nickel-based anti-sieze compound. Ni-base anti-sieze is formulated for high-temp applications such as exhaust systems. No need to add copper-based a/s.

I bought sensors for both my 400E and 530iT BMW from these guys. Give them a E/call

I also spliced in the Bosch 13953 on my '90 300E 2.6. I marginally passed smog two years ago so I changed it before this years test. Passed fine, with lower emissions that two years ago.

It took about 20 minutes to splice and solder the new sensor in place of the old.

My advice it to solder and heat shrink it and have your splice inside the car to avoid any weather issues.

Thanks for the tip on the 4-wire sensor. I'll change the '94 as well since it is due for smog in the next few weeks.

i am about to change my O2 sensor with the Bosch 13953
also. i looked at my wiring and found two existing connectors,
one is a two-wire connector(with red and brown wires),
the other is a rounded connector with solid green wire.

so, where do i cut and splice? your guidance is appreciated.
the car is a 89 260E.

joel

If you have a 3-wire O2 sensor, it would mean 1= 12 volt power ( probably red ), 1= ground ( likely brown ) & 1= signal wire ( likely green ).
You can verify this with a DVOM.
Red = 12 volt
Brown = ground
Green = fluctuating voltage ( between 0.1 to 1.0 volts, or it may be locked in at @ 0.5 volt. ;)

hey manny, thanks. i have yet to buy this mustang O2 sensor and am not sure if it comes with what kind of connector. i hope i can re-sure my oem connector.

cheers!

Mustang connector
 

My archived notes tell me the mating connector from Ford is:

Mating Connector (Ford dealer part number AUVC927082, $9.06 – for a 1990 Mustang 302).

It is suggested to use this connector so splicing has to be done only once. Then your new O2 sensor can be replaced at will with a simple disconnect.

Kestas, thanks for the tip. i hope the ford o2 sensor
comes with enough length of wires for me to re-use my
connector.

cheers!

Re: Mustang connector # AUVC927082...

A few weeks ago I checked for this at my local Ford dealer. They said it is no longer available. They also confirmed by year & model lookup. Too bad.

I also used the Chrysler 4-wire O2 sensor on my 1995 e320. I tried to get the mating connector from chrysler, but found it no longer available. 30 min. at the junk yard, I was in business. Easy job to do, I used what are called "environmental splices" and heat shrink on top of that. So far, it works flawlessly.

found in catalogue, o2 sensor NTK universal. Per above post
of Arthur Dalton is better. Does anyone knows if NTK comes
in 3-pin variation?
