Tuning trouble??
Have a 01 TA Ws6 a4, has mild cam full exhaust and converter. Nothing too major. I have had the car dyno tuned. The trouble that im having is the o2 sensor on the driver side, bank 1 sensor 1 is not responding. The passanger side is working just fine and I have the back 2 sensors deleted. I have changed the sensor multiple times, gotten new extensions, and even went back to the shop that i had it tuned at to look at it again. I have latley re-run new 02 wires from the pcm to the sensor and that is not fixing the problem either. Is there some way that the tune is messed up?? Only reason that i ask this is because this sensor that is not working is reading the same mv as the 2 that are deleted approx 447-450. Please help, i just dont know what to do anymore.

Yes, wires where changed all the way back. Ran completly new ones, and still doing the same thing. When I check to see if there is continuety in the wires there is. Its just not reading them in the computer for some reason and dont know why.
also to previous post, I did swap the sensors side to side, didnt make a difference. Still no reading on it.

He also bought a new PCM from the guy that tuned the car. Did the same thing as with the old PCM. I think somehow the tune is f'd up, cause all the tuner did was copy the tune into the new PCM and not re-tune it and it does the same thing.

Also is there a way to look at my tune with HP Tuners? To see if its messed up somewhere?

Ok cool, thanks for your help. I called the guy that tuned my car for me and hes going to email me the tune so that i can post it, so you guys can take a look at it for me.

It's not in the tune. The 02 reading 440-450 mv is an open circuit. Where/how are you taking your resistance readings? Are you only checking to the connector, or are you checking past the last connector to the wire ON the 02 sensor?
How did you replace the wire? Did you butt connect a wire in, or replace the actual pin in the ECM connector, as well as the pin in the 02 connector?
It's probably just the female pin in the 02 connector that's spread open. See it all the time.

As for checking the resistance of the wires i used a multimeter.

That value (440-460mv) is what both of my O2's read when I key on before starting the engine.
Both of mine work fine.

Both of mine work fine. That reading is with the car running, and heated up. Get the same reading after 20 minutes of driving.

[QUOTE=ws6fitz;11266959][QUOTE=Sid447;11265381] No response from them then.
I'll have a look at your tune when you post it.

not all o2 sensors are made correctly,, i have ran into this 3 times, gm pcm needs the grounds for the o2 sensor to actually be grounded inside the sensor to the case of the sensor so the pcm can use it as a ground,, many of the aftermarket o2 sensors are not grounded from the actual wires to the case of the sensor inside
all 3 times i fixed the issue easy by splicing the heater ground and the sensor low(ground) together
take a factory o2 sensor and check for continuity from the sensor low(ground) to the case of the sensor if you have continuity your ok if not you need to splice the 2 together, make sure you are checking the sensor low and not the heater circuit ground
