What brand?

 

So the sensor is fluctuating between 0 to .9 volts rapidly as it should?

 

The new one is Bosch OE replacement...not funny

The B1 is just in the middle, B2 is reading riich, hovering in the .900+ region at the top of the scale in the dashboard display on hpt.

 

Hey, you can get a Husky 3 ton jack @ Home Depot for $50 and 2 Husky jackstands for $24.

 

Can HPT do active tests, such as increasing and decreasing injector duty cycle? It would be nice if you could decrease fuel and see how the sensors react. Are there any pending or current codes? Maybe you have an actual rich condition, or the sensor is plugged in incorrecty like BlackGMC mentioned, and the PCM is compensating by richening the mixture, giving you the .9 reading on B2. Does the plug for the rear sensor stretch far enough to get it plugged in wrong?

Sorry for all of the questions, trying to gather enough info to help

 

I live in a duplex and have no room for any more tools, it really sucks not having a garage, let me tell you.

I do not know enough about hpt but I am pretty sure you are correct that B2 is compensating. My forward O2 is back way further than stock, in the collector (LT's) so I think it's entirely possible.

 

Hey Bill for the time being try logging B1S2 and B2S2 and see what they read. That will tell you if you have them plugged into the wrong place.

 

Gotcha....hopefully that's the problem (wrong connector)....I hear ya on not having a garage too, I live in an apartment and all of my tools are at my in-laws, filling their garage. Sunny weekends are imperative to me getting any work done

 

Thanks Chris, great freaking idea...at first it was 447 then it started getting richer and richer!! I believe we have a weeener!!

 

I'm about to do a header install out in my apartment parking lot
