I have been searching and searching for info on o2 simulators. I know what kind I need but I cant find anywhere that shows how to wire them in. I have been told they need to be wired in AFTER the stock o2 Sensors since the stocks need to stay plugged in to the harness. Is there a write up on these? I want to get the o2 sim installed before I take my car down for the header install.

Please help!

Thanks

O2 sensor wire colors? O2 simulator install, check this out and search for O2 simulator installation and you'll find all the info, it's easy and helpful...Good luck!

One other question. The place i was going to buy from (o2simulator.com) has been "down for maintenence" for over a moth now, cattman doesnt carry them, and the only one I can find is this one on ebay w/ an integrated heater circuit.

http://cgi.ebay.com/O2-OXYGEN-SENSOR...3%3A1|294%3A50

would this work for my application?

 

Hey guys I found another O2 Simulator source go to 3sx.com under electronics the dual o2 simulators are $49.95

 

02sim.com seems to be working fine.

I did my wiring job this weekend and because I didnt follow directions closely enough, I had some problems. Here's what I did wrong, and right.

I read (splice in) as cut and splice in, whereas instead of cutting the ground and power from the harness, I should have just spliced in the red wire and black wire from the sim to the car's harness and only cut the white wire. Luckily, I'm pretty good with a soldering iron so I soldered, heatshrunk, and taped the wires back together with the splice in.

Before fixing my mistake, I had only the heater wire connected up. This caused me a p0161 after 10 minutes or so of driving. Once I rechecked this website, I saw what I had done wrong and redid my wiring. It was super cold out with wind, so i used the 40 watt setting on my soldering iron and it was simple to fix. Drove 45 miles (40 minutes) to work today and the light has stayed off so far. I did not need to use a resistor at all since I hooked all my wires back up.

To summarize.

On a 2000 infinity, here are the wire colors I used from the car's wiring harness, about 3 inches before the plug:
White=Sensor wire. Cut this and splice to your simulator
Red/Blue=heater wire. Do not cut this, leave it alone.
Red/Yellow= +12 volt wire splice your red simulator wire into this harness, but do not cut the wire.
Black Wire=ground. Splice your simulator wire into this one,but do not cut the wire.

I bought a dual output sim since I have a cali spec car. My bank 2, sensor 2 was bad, which is the connector 2nd from the left. Mine had a red heatshield on the sensor harness. I had a P0430 error code. I now have one spare sensor wire to use should my other downstream o2 sensor goes out(which would be a P0420 and all I have to do is cut the white wire on my other harness and splice the spare white wire into that white wire since I already have power and ground to the simulator.

Easy to do once you do it. Be prepared to take about 15-20 minutes to do it right with heatshrink tubing and black electrical tape.
