Frankly, i don't know what half these #'s SHOULD be...The o2's are ALL OVER the place.... .100 up to the 800 range...
I don't know what i'm looking at... ....Help please

 

Anybody???? I'll e-mail it to you.....

 

I'd get a jump start on the answers for yourself by heading over to Injuneer's helpful webpage.

I know that info looks daunting at first, but Fred really does a great job of making things as easy to understand as possible.

Of particular relevance is this quote:
"So, you will see that, since the PCM updates it's calculations nearly 10 times per second, the O2 sensor voltages are going to be cycling rapidly back and forth between 100 and 800mV, and you might even see values as low as 050 mV, and as high as 950 mV. THIS IS NORMAL."

But really -do look over the page. I'd bet nearly every question you could come up with is answered there!

 

John, email me:

I'll look.

 

Thank you Jon. You have mail!
