Thread: Regrounding the O2 Sensor

Before I do the resister mod I will use a torch to heat it up and see if that helps.

If it does I'm buying another O2 sensor from that eBay seller, can't beat the price and low $ very fast shipping.

What kind did you find for $55?

i got that 13275 sensor off ebay for $20 shipped. just got it today, came in a ho-hos box too. looks like a nice piece though.

Nice deal!

I honestly don't know why there are different versions, except for OE specific connectors.

Don't all front O2 sensors work the same way pretty much?

mine came with a connector on it but i dont know which model the connector fits. it looks like an oe size connector so i may be able to track one down

Ah thats what I figured, well I think it should work the same

It was a Bosch Universal O2 sensor (with Bosch connector pak) but they didnt have it in stock. Takes 4 business days. So, I ordered it today.

So today, Im trying to do a NX power window & lock conversion. Without much luck.. The door locks works all screwy and appears to be automatic only one way!! Real stupid design... Im just testing the electrical part after rewiring a 91 NX parts for a 93 NX (Wire colors are different & harness plug wire locations are completely different too). This project sucks too...

Silva: Check first.. The threads maybe different. Try installing it. If it installs, just use your connector from the old 3-wire connector and run the 4th gray ground to the Intake Mani like Vadim did in the pictures above. That should work fine.

Car is fully running! MPG testing begins today!

I have couple other projects on the back burner that I can't touch until I get some numbers from this O2 sensor

What projects? Indexing my Iridium spark plugs and Killing the Rear O2 CEL, which will show how badly a CEL will affect the Gas millage.

I fueled up today, as always 93 Shell Gas, I fueled up 2.1 gallons. This is for 22.5 miles of driving, then car standing for a week. I redlined the car only once. Thats like the all time low for me, ~10MPG!

Your MPG numbers will not be accurate until you fix the other O2 or apply the resistor mod for it.

But happy to see you rolling again!! Alty must be fixed too!!

That is true, but every single MPG tracking that I have down has been down with the CEL for the Rear O2 sensor.

If I were to fix it right of way, that would be two different veriable changes, thus I would not 100% know if my MPG's improved because of the 4-wire O2 sensor or because of the CEL not being there



Not too, that was the show stopper for me

looks like the 13275 fits most late 80's and early 90's chrysler vehicles. Were the o2 sensors all pretty much the same thread pitch in passenger vehicles of the same era at least? well i guess ill try fitting it tuesday night. i know where to get a connector from now too.
