The other day in the middle of reflashing with Ecuflash and tactrix 2.0 my computer disconected, stopping the flash in the middle (I had a usb problem). I was forced to unplug close and reopen ecuflash. Plug into a different usb and start the flash all over again. The flashing works fines now and does everything I want it to short of one issue.
ever since I started modding my car I have had my wideband in place of the rear o2 so I have had the Rear o2 heater patch in. never through a cell untill this happen. Now I cant get rid of it. everytime I clear it is instantly returns that the rear o2 heater is out even though I have the patch in.
could someone please help figure out what is going on and how to fix this. I have an 06 MR running ROM 88590015

 

Is the cel's number/description related to the 02 sensor?

 

there are 2 codes for the rear O2 sensor..

first one is the patch itself and the other is for the heating element in the sensor. to get rid of the CEL you have you need to put a resitor in the connector of the O2 sensor across the heater wires to take the CEL away

there is a thread on here some where that has the resistor size and which wires to put it across so your going to have to search for it

 

yes the cell is for the rear o2 heater. I have my the narroband output from my wideband running into the o2 sensor feed in the ecu. I then have the Patch For the Heater so instead of running using that little resister trick that some have done it am using the heater patch and retaining the ecu reading rear o2 levels.
That patch and everything has always worked perfect. something happened when the flash was only able to write half way. now it seems like it isnt accepting the patch at all.

 

i would suggest try flashing back to an old rom like your oem rom and then after that flash in your current rom.

 

ya, tryed that, still nothing

 

can you read the current rom on the car and check to see if the periphery bits are set correctly for the rear 02?
