Hi Guys,

In the process of mapping with Proto. Todd says he does not see any O2 readings in my log files. Any ideas what could be causing this. 1 of my Pre cat Sensors is brand new, the other has 45Kmiles on it. Lambda readings are fine and the ecu sees the sensors plugged in, just no O2 readings?? I've checked connections and secondary air pump. Used Durametric to run secondary pump manually. All works fine. Any help would be much appreciated as I am STUMPED!!

 

Lambda readings are O2 readings.

 

You can tell Todd that!! Thats not what he said to me!

 

My Durametric outputs the following as a header for the lambda columns:

Oxygen sensing, bank 1 Lambda Value
Oxygen sensing, bank 2 Lambda Value

... so I agree with _gez_

maybe you never checked them off to be logged?

 

Plus one..

 

Oxygen Sensing Bank 1 and Oxygen Sensing Bank 2 were both ticked

 

And you got lambda values from both banks, correct? So what's the issue?

 

The issue is.....the O2 readings are 1.00 forever and ever, regardless of revs or gear or load or speed or anyting. They flatline at 1.00 and stay there.

 

You said in your original post that "Lambda readings are fine." If they are forever 1.00, then of course they aren't fine. That's what confused me, and I think the rest of the people who have been trying to help you.

I suggest that you post a log from a boost run, and then you might get some more helpful responses.

Ok tell me what to log and I will go for a drive and log it.

 

Why not post precisely what you sent to Tony?

Posting a different log will not answer the question of why what Tony got is no good....

 

I think you got it wrong... it needs to say "Oxygen sensing bank 1 Lambda Value".
you are logging the wrong values..

 

Interesting. So what he ticked was "tell me the status of the Oxygen Sensing" ...which was "on" or "1"

What he wanted was the actual values....

 

thats what I'm guessing...
