Installed Standard Motor Products SG130 O2 sensors $16 each on my 95 LWB

Hey All,

I don't see much for followup on repairs on this forum so figure I should pay back a little. I had to remove my front exhaust pipe to weld up a crack so I took the time to replace the O2 sensors. It is lots easier with the pipe out. I had read that the titania O2 sensors used on a range of late 80's Nissan Maximas would work on the later RRC. They physically fit, they are titania sensors, the three wire colors match and the SMP (standard Motor Products) SG130 is only $16 (w/shipping) on eBay. Yes you do have to cut off the Nissan connector and reuse your old connector. The housing does have NTK stamped on it too. I purchased my Rover (95 LWB) at 135K miles and I'm now at 204K, the O2 sensors I removed appear to be original, I would get a 44 or 45 codes if I let her idle more than 5 minutes when hot, and at $32 bucks why not. I purchased from eHerko (eBay) who also listed the NTK25016 for $52, which has the Rover connector and is Rover specific. The Nissan specific part I used has interchange numbers of SMP SG130, NTK 24007, Bosch 13021, and Denso 2343129.

I have nearly 1000 miles on them so far... no codes yet, last two tanks of fuel came out 15.3 and 16.6 mpg mostly interstate at about 65mph with some head wind. Runs well for an original 4.2L with over 200,000 miles. I changed out the plugs NGK BPR5EGP at the same time, Bosch Ignition wires and Lucas cap and rotor have about 30,000 on them. The plugs had 75,000 and the gap had opened to nearly 50 thousandths so they were due. Only issue I have right now is the Idle Air Control seems a little slow to respond at times.

Hope that is helpful information. Jon

Thanks for this information. I just installed these on my '95 SWB and so far so good. I have yet to determine gas mileage but it ran very smooth all day long.

Re: Installed Standard Motor Products SG130 O2 sensors $16 each on my 95 LWB

Yep, I installed 2 different titania sensors on mine after I replaced the cats. One was a Nissan replacement, the other was without a connector. Soldered my connectors on with new heat shrink, you can't even tell they're not OEM now. In fact, in taking apart the OEMs, they are all just crimped and soldered together to mate the common O2 sensor to whatever connector the drawing requires. They were both NGK's, $42 for both delivered. I scrounged around for a while to find those. Some PNs you can look for:

Airtex 5S3787 and cross reference parts: 2269061A00, 2269061A10, 2269061A20, 2269067S00, 2269069A01, SU4491

SMP SG130 and cross reference parts: #2269019P20, 2269019P40, 2269021P00, 2269028F20, 2269061A00, 2269061A01, 2269070F00, 2269070F10, 226A01M500, 226A01M560, 226A070F00, 226A070F10, 226A070F65, SG233, SG538

Mine went to a 1987 NISSAN SENTRA 1.6L L4.

Thanks for the information. I just installed a Bosch 13021 O2 sensor and works perfectly.
