<img src="/forums/images/graemlins/cheers.gif" alt="" />Since I've seen a lot of threads lately asking about 02 sensors i thought I'd post this.Sparkplugs.com has Denso OE identical 02 sensors for $37.75+ $7.98 shipping.The part#234-1051.This is for the 22re.They also have other styles for different motors at low prices.Hope this helps you folks out! <img src="/forums/images/graemlins/kewl.gif" alt="" />

That's where I got mine last year. Fit fine and seems to work well.

Bought one there last month for my '86 and will probably buy another for my '85 shortly. <img src="/forums/images/graemlins/smile.gif" alt="" />

What is the indication that you need a new one?

Your check engine light
I don'T remenber witch code...

<img src="/forums/images/graemlins/kewl.gif" alt="" />I have an air/fuel gauge which shows that the 02 sensor is sending a good reading to the ecu.It has indicator lights that should constantly flash up and down the scale of the gauge to show the ecu is constantly looking for the right fuel mixture.Right now the 02 works when the cold start high idle is running.But it seems to stop working after warmup.I just get a constant set of lites towards the lean side of the gauge with no flashing.I'm not sure if this is open or closed loop on the ecu.Maybe someone a little more knowledgable will chime in about that. <img src="/forums/images/graemlins/cheers.gif" alt="" />

I notice that the sensors are marked front and back. I only have one and it's infront of the cat. I beleive my truck is technically the dlx model (must not stand for deluxe cause I've got no power options). So which one would I need? <img src="/forums/images/graemlins/confused.gif" alt="" />

<img src="/forums/images/graemlins/cheers.gif" alt="" />If you've got a 22re,then the same 02 sensor will work on your truck.I also only have 1,it's just below the exhaust manifold.It's a single wire sensor. <img src="/forums/images/graemlins/cheers.gif" alt="" />
