I got the code a month after flashing, it was come and go for a few months then one day it just dissappeared for like 4 months. Came back this week, I'll eventually get to replacing the O2 sensor..

 

thats strange because I have a 2008 also and I thought that was only for the 2006 models...I wonder if the is why my O2, Cat, and Evap wont turn "ready" for OBD2?

Could hondatas software cause this?

 

i have an 07 with no secondary o2. what is the code it is throwing? system too lean? reset your light and do a datalog of normal driving and cruising at a steady speed. go back and check your air fuel ratio which should be @ 14.7 and also check your o2 voltage to see if its jumping all crazy or flat lining out. you can troubleshoot by just datalogs!

 

The car isn't throwing any codes...yes the car is running lean on the basemap due to me breaking in the clutch and diff before the tune with evans tuning. Evan said my A/F ation was fine for light throttle (>20%) and out of boost. Could a lean A/F cause the O2, Cat, and Evap to not be ready? Also could my Berk 70mm HFC cause all this?


nevermind about the HFC i swapped the stock cat on logged ~15 miles and still no "readiness"

 

I need a Flashpro for idiots book.

 

So all the folks that change their sensor had the problem resolved? It seems like an incompatibility between FlashPro and the old type of sensor, mine had 20k when it happened and a week after the flash, thee odds of being o coincidence are quite low..

 

The original 06 sensors were recalled. The official letter from Honda is floating around somewhere in this forum.

 

Anyone got pics of the old and new sensor? I ordered my FP and should be here early next week.

 

I'd say they probably look the exact same.

 

In the other thread someone said it looked more like the Bosch/PLX unit implying it looked different.
