Has to be a problem with the O2 eliminators. Reseat them and use the dielectric grease. I find it hard to believe both would be defective though...

You left the O2 sensors installed, unhooked them from the factory harnesses, and put the eliminators on the other connector (not the one wired to the O2 sensor)....Correct?

 

I've had them for two months. Pretty nifty tuner, eh?

 

Correct. I suspect that one of two things may have happened: (1) The OP has the O2 sensors still connected and the PCV is enrichening the AFR's more than the narrow-band sensors can correct to their designed 14.6:1. When this happens it produces a fault code, but one low and one high is confusing. Or, (2) the second fault suggests the sensors were unplugged and eliminators not installed.

I'm not an expert on fault codes, as I've never had one on this bike, and am just guessing. Maybe Jamie will jump in and enlighten us.

 

No, no problems installing the sensors. My only problem was getting my fat fingers to the rear cylinder sensor plug. Other than that.....

Like you, I find it unusual that BOTH would be defective. I even went out and checked the 'codes' again...just to make sure. Sensors were unhooked, left in place with pigtail tie-wrapped, and the PC V Sensors clicked right into place. This afternoon, a co-worker and I went out....removed the sensors, coated with grease, and reinstalled.

Opposite codes on front and rear cylinders is confusing. Like I said, I checked them TWICE...same co-worker watching over my shoulder. After coating with grease, I went thru the sequence of 'cancelling' the codes...with success. Then we started the bike up....and they're back again. 131, 134, and 151.

I talked to Keith @ FuelMoto this afternoon.....he said although unusual that BOTH would go bad....he was gonna send me another set. Should be here by the weekend.

The bike's running like a champ.....actually never better. Throttle response is unbelieveable....Im wishing I had put the PC V in sooner rather than worry about warranty. Live and Learn.

More to come as it happens. Thanks guys for all your thoughts and help.

Did you remove the stock O2 sensors??? Are you running the PCV Autotune sensors or did you reinstall the stock O2 sensors? If you did not go with Autotune I'm trying to figure out why you pulled the O2 sensors (if you did...sounds that way in your post).

If the O2 sensors are screwed in snugly in the pipes and disconnected, then your problem is not the sensors...though the code indicates it is. The eliminators should be fooling the ECM into believing the sensors are plugged in and that all is well.

If you have an Ohm meter, remove the eliminators and plug into both terminals to check for good continuity. If you have continuity then it is not the eliminators.

If you are not running Autotune, the the only thing left is the connections at the PCV and ECM. Check each for fully seated connection and check for any bent pins.

If you are running Autotune then make sure you are plugged into the data port under the left side cover by the fuse block. ( at least that's where it is on my 09). I tried the same type plug under the seat in front of the battery and it would not work, although I did get some ECM data, the autotune would not work in this port.

 

LOL....OK....let me clarify my 'babblin'.

I've used the term 'sensor' to describe too many things. The original HD exhaust O2 sensors are in place, in the exhaust pipes. I did not remove them. I unplugged each 'O2 sensor' harness, front and back, secured the loose, unused harness plug (female) out of harm's way with tie-wraps, and installed the male end of the HD harness into the female PC V 'module' (terminator, eliminator, etc), securing each, again with tie-wraps.

Hopefully that clears things up a bit. Last nite, I went thru the 'codes' again, all recording "CLEAR". Im about to leave for work; before I crank up, Im going to go the the motions of checking, recording, and clearing the 'fault codes'. If all is well, I should record a "NONE".

I'll know in about 45 minutes or so.

Sorry for the confusion...I only APPEAR to be stupid....lol. (then again, I have my days)

Went to Independence Harley in College Station and seen J R in service hes a graduate of MMI in Arizona.
They dynoed my 08 FLHT that I did a 103cu 2 weeks ago today, It dynoed out at 100hp and 104tq.

Got J R to take some pictures of the frame that the paint come off of to send to Harley, He said he was going to contact the HD factory Rep that he wants to git them to come to Independence Hd and git me over there and see if they would let me have a new frame. He was statin that with the high moisture in the air and the salt in the air if the bike had a pinhole in the power style coating it would make rust under the coating and make it come off like it did on my bike.
So I got to wait for steps to go threw before my my warranty runs out in Oct. This was really important to me.
Here is the frame picture.
