o2 sensor woes. help!

[highonoctane16]

Hey guys, I'm not getting any responses on 'that other forum' so I figured I'd ask here too..
I'm having some o2 sensor problems that I'm hoping someone can help me sort out as I've fooled with it and just cant find the problem myself.

A few weeks ago I was driving along and my cel light came on. I pulled over, hopped out, and the o2 sensor wires had fallen down onto the exhaust manifold and all 3 wires fused together. I started by cutting out the bad section of wires, and splicing in new wire to replace what was melted. Cleared the codes, and still a cel. At that point I assumed something must have shorted out when the wires crossed so I ordered a new sensor. I put it on and I'm still getting the o2 sensor code... I went to the tsrm and broke out the multimeter and checked the resistance between the two heater wires at the plug and I'm getting between 6.8 and 7.3ohms. The tsrm specifies it should be between 3.0 and 3.6. Just to humor myself, I checked it on the old sensor as well and also got around 6.8ohms. I also checked the voltage between vf1 and e1 with te1 and e1 jumpered and got 0v just like the tsrm says it should be...

Does anybody have any ideas or suggestions before I call oxygensensors.com and tell them they sent me a bad sensor? **Or would somebody mind running out and checking the resistance between the two heater wires of your working o2?** I'm stuck on this issue and I cant afford to be getting such bad gas mileage becaue of this thing! Any help would be greatly appreciated!

**this would really help!

when you bought the new o2 sensor did you buy one that came with a new plastic connecter or the kind with just some butt connecters where you have to connect to two odd ends of wire?

You didn't specify, but did you clear codes after you installed the new O2 sensor?

Cleared the codes, and still a cel.

I've cleared the codes religiously, time and time again.

I bought a non-terminated sensor. Same as I bought last time from the same company and the old sensor has worked flawlessly for the past 2 years. The splices into the plug wires should not be the problem. They have been soldered and heat shrunk. I also have a brand spanking new wiring harness and an ecu that has never given me trouble before.

Any other ideas? Would someone with a multi-meter mind checking their resistances? It would literally take 5 minutes and help me tremendously in diagnosing this problem.

tell you what, i dont have a multimeter, but this is just motivating me to just go out and get one, i will post tomorrow or later tonight if i can buy one this afternoon.

You dont realize how much of a help that would be! You can PM me or reach me on aim if you'd liked. Thanks again. Dan
