Oxygen Sensors

[Rizzoj2000]

04 TB. Are both Oxygen sensors on this vehicle the same part number? should I stick with GM or are Bosch ok?

No. The exhaust manifold (engine bay) o2 sensor is AC Delco p/n 213-1698
The rear (post cat) is AC Delco p/n 213-1574

I have read that AC Delco is the way to go for the front. Although some members do not report any problems with Bosch in the rear.

 

[Rizzoj2000]

Thanks for the quick come back. I think I'll stick with the AC-Delco.

downstream you really don't need to change it unless you have a code or purchase a new CAT....

True, but if he's willing to just knock them both out since he's already down there it's feasible. The upstream is known to get "lazy" after a while, I would bet the downstream may also (though in a perfect scenario there should be no or very little fluctuation in voltage anyway) but of course it wouldn't affect fuel economy.

Check your 02 mine came with a Denso from factory.

 

[Wooluf1952]

IIRC, Denso makes/made the AC Delco O2 sensor. Bosch is the one our trucks have a problem with.

 

[Rizzoj2000]

Thanks for the info guys.

Yup, usually Bosch is a bad idea. That said I had a Bosch in mine for quite a while and never had an issue with it, but given the history I'd rather just use a known good sensor brand to start with and not risk it.

Besides, the Denso was cheaper than the Bosch anyway.

Denso is also cheaper than ACdelco. Make sure to use a copper anti-sieze or copper gasket on the threading.

The AC-Delcos I bought from Amazon - referenced in above post - already had the threads precoated with anti-sieze. I was very pleased with that.

What about NGK sensors?

 

[The_Roadie]

I think I've read about members using NGK plugs, but I'm not recalling any discussion about NGK sensors. In the absence of data, go with what we know works.
