Well, in the meantime I am running the v5 patch from Tephra, what resistor do I need?

I am confused from the first post it seems like it is working for him but others in the post have said it gets too hot....etc...so whats the right resistor? Has anyone had any luck with their testing?

i have the resistor unther the car fixed to the pipe heatshield wired thru the original sensor so it does not mater if it gets hot i am woried about posible short so i am jut waiting for the heater patch

 

If you've got a current meter, the ECU looks for a current between 0.17 A and 10.5 A across the heater when the heater circuit is engaged, and then it looks for a voltage of > 2.0 V across the heater when the circuit is not engaged. The current seems easy enough to measure. Not sure where the ECU is measuring the voltage (wouldn't seem to be across the O2 sensor), so not sure how to measure that.

 

Where is this connector?? under the passenger seat?? Not find it Help-me!!!

 

That's the plug under the passenger seat (and under the carpet, if memory serves) that connects to the rear O2 sensor under the car.

 

its not really under the p-seat, more like under the dash where the feet go.

just pull the carpet back on the side that the gear stick goes you should see it!

 

Its under the seat!

 

must be different on different evo's

mine is inside the kick panel..

 

I see under seat passenger and next view under the carpet, and no look this conector in wher site, only see metal white
It is necessary to remove all the original carpeting for see this connector?
Show me one photo, please!

Other question, Kick Papel... is under Ecu?? or where is??


Sorry my bad english!

 

its beter to go the other way, you can go under the car and see where the wire comes to the inside of the car, there are many groomets on the flor and by what i see here not all evos use the sameone, mine its wright under the pasenger seat under the front left corner of the seat, hope these helps pictures tomorrow

 

Ok! Thanks, waiting the photos for my trouble!

 

I put the resistance between yellow-red and yellow-blue. Now the car new error, the P0141[Heated oxygen sensor heater circuit (sensor 2)].

Help-me please!

 

"I have a software fix for the Rear O2 CEL for the Evo IX 88590015 ROM" that leaves the O2 sensor in place and does not throw a CEL?

Still no fix that completely eliminates the rear O2 sensor on the evo 9 with out a CEL?

 

its very prehistoric, but you can kill the cell with a antiflouler extention that the o2 sensor bolts into. I know it works, even catless.

 

well yeah i knew about that just wanted to ask for another option.
