Which Oxygen Sensor

[wjayg]

I search the threads here and did not find a good answer for my 1990 SHO
Rock Auto has so many choices and I am gathering the Bosch exact fit 13942 are the best for my year SHO?
Also where can I get the oxygen sensor tool you talk about?, how much and what is so special about it? I thought just a open end wrench would get it?
Also learned to disconnect battery w/ headlights on to reset computer-thanks

I have always used either Ford or Bosch. The only difference between all the Bosch sensors is the length of the connector. As for the tool Auto Zone or any parts store will have them. Not sure which sensor you are replacing some are a little more difficult to get to than others, I would buy both the wrench and socket oxygen sensor romoval tools.

 

[randy'sho]

bosch are just fine! You do not need the special tool at all for your mtx....it shouldn't take you more than ten minutes to change both!

Oxygen Sensor

Thanks, Your SHO looks bad, 32% tint which brand?

 

[randy'sho]

thanks....hummmmm I'd have to look to see what the tint brand is!

OEM are NTK/NGK. The special tool is only a deep socket with a slit to run the wire through. POS if you ask me. Only good for saving a working O2 sensor assuming you can't get a 7/8" open end wrench in there.

See my reply in this topic. The 13924 is the exact fit. The O2 sensor socket is available through most auto parts stores for about $5. It will allow you to use a torque wrench to properly install the sensor. The Bosch sensors come with a dab of anti-sieze, but make sure it is present on any sensor before installation.

The prices will have changed from this 2007 topic, but here are the numbers for the SHOs.

3.0L: Bosch 13942, AutoZone/AZ.com, $ 39.99
3.2L: Bosch 15716, AutoZone/AZ.com, $ 42.99

I know this is an old thread, but my question is an old question. I've searched the board but couldn't find a clear answer.

I want to change both O2 sensors on my '89 SHO. Are both sensors identical? Do I need TWO Bosch 13924 sensors? Is the connecting wire on the 13924 the correct length for both?

The only difference i know of on our car is the length of the pig tail on the sensor. I always just buy two of the longer one and have yet to show any negative side effects.

 

[sperold]

The two O2 sensors are the same (both upstream or Sensor 1s).
I have only had good luck with the Motorcraft and Denso manufactured units.
I once had new sensors that turned the light on when the rpm dropped below 2000 rpm. On the highway the light went out and stayed out, till the next slowdown.
The connecting wires are never overly long, but they always fit.

For the '89 SHO, what is the p/n of the longer one?

Which brand sensors caused the light to turn on when the RPM dropped below 2000 RPM?

Do you have the p/n for the Motorcraft and Denso sensors? Do you have any experience with Bosh O2 sensors - they seem to be highly recommended.

Bosch 13942

The prices will have changed from this 2007 topic, but here are the numbers for the SHOs.

3.0L: Bosch 13942, AutoZone/AZ.com, $ 39.99

O.K., so for my '89 SHO I need two Bosch 13942 O2 sensors, correct?

1991, 430K miles, and rolling...

God Bless ya, my '89 has 285K miles on it. For the past ten years my SHO has spent most if it's time in my garage while I took the subway in Boston. Living outside Fort Worth Texas, I'm putting more miles on it now.

The Motorcrafts are DY605, about $40.00. The Densos are 2343002, about $24.00 and the Bosch are 13942, about $25.00.

I would pick any of these.

I snooped around and found my O2 sensors that gave the crazy results, one was a Bosch and the other is a mystery. The Bosch had a body size almost as big as the hex that is used to install it. The other had a very small body size that looked like it was made in 2 pieces and pressed-together.
My guess is the Bosch was OK and the mystery model was installed by a garage that does emission tests and probably worked OK for awhile until it developed the check engine light habit.

 

[DeepPower]

If the Bosch gave you "crazy results", then maybe I should shy away from them.

It sounds like two of the Denso 2343002 is the best way to go? According to the photos I see online, the Denso doesn't come with a wire attached, is that correct?

 

[sperold]

Don't be afraid of the Bosch, it is pretty well a sure thing it was the orphan O2 sensor that gave me the problem.

I had good luck with both Motorcraft and Denso. I tried Denso because I read something that indicated they were the OEM supplier.... whether that was true or not, who knows.

A lot of repair shops buy no-name O2 sensors by the dozen for a few dollars each and put them in wherever they will screw into... which is what happened to me. But you always pay the Motorcraft price, no matter what they put in.

The sensors always come with the wire lead, no worries there.

Any of those big name suppliers will give you good service. I tried the Denso's because I got tired of paying the big dollar for the Motorcraft, and at that time I was not installing them myself. In that situation, I picture the installer dropping the O2 unit once or twice before he gets it installed.... so why pay the big buck when you can't guarantee it will go well anyways.

 

[DeepPower]

I bought two of the Densos. From a web search they had the least complaints - also they are supposed to have a coating that protects them from carbon deposits.

 

[sperold]

I can vouch for them, and the price is right.

I try to use the original parts whenever I can, but when the price gets too far out of line, you have to face reality.

I have had many failures on parts from the so-called preferred vendor after paying a premium. I bough spark plug wires from the premium supplier... had them installed... only to have the engine compartment light up like a Christmas tree at night. Sure, they stood behind them and gave me a new set, but I paid to have the intake removed for the second time for the installation, and that never got recovered.

Good choice.

Got both of them from Amazon for $25.21 each: http://www.amazon.com/gp/product/B000C5SFWS/

You know, I've checked my records and I suspect that after 281K miles I've never replaced my O2 sensors... betcha that will get rid of that faint gasoline odor from the exhaust, yes?

 

[SHOtimer]

No, it won't.

But, you should really start a new thread for additional problems.

It may, after you install the O2s it's sometimes recommended to pull the battery for a few hours to reset the computer, however this isnt is a require thing.
