ok so i just finished my mini me i did everything bu the book the only problem is the cel po132 im using rywire extensions since the y8 manifold has the o2 on the bottem.. i do not have my cat yet so i just have the secondary hanging there

i have my scan tool and the live data is saying its at 1.275 which is fine apparently.. i still have regular gas instead of super.. so im guessing the extension might be the problem?

swizz977

also the voltage for the o2 was stuck at 1.275 it was not jumping around at all im not sure if thats right ot not

swizz977

could it be that i just have the secondary just hanging there? something is not right if the o2 is flat lining then there is no signal coming from the o2 at all im guessing

swizz977

it was shwoing both o2 flat lining at 1.275

What engine harness are you using?

swizz977

my y7 one i wiwred everything the knock sensor the vtec switch solinoid ground i did the 3 to 2 wire for the iacv did the wiring for that on the ecu plug like i said i did everything by the book the only thing is the ry wire extension.. it seems like im not getting any signal from the primary o2 sensor at all ..
im using a y8 obd2 ecu the same as my 00 obd2b y7 harness..

If the only thing you extended was the o2 wiring than that would be my first guess. One of those wires are actually isolated from the rest.

swizz977

thats my first guess too .. im thinking maby the wires are too long to give it a reading.. is there a way i can test this?

tony_2018

Disconnect the extended harness, reset ecu and plug the o2 back in and start the car to see if the same error comes back. I'm sure you're going to be getting a new code but that can be cleared.

swizz977

well what do you mean i cant really plug in the o2 without the harness since it doesnt reach

swizz977

ok well the is wierd but i tried another o2 sensor and its working now so for skme reason both of my o2 sensors that were fine before the swap do not work now for no reason what so ever

tony_2018

Depends...just gotta be careful with them. But I never got that error message with a bad o2 sensor

swizz977

im not sure why eather.. my o2 sensors werent giving any reading at all for some reason it was just stuck on 1.275

swizz977

ok i reset the battery plugged the cruise control its much better now i just threw a code for the secondary o2 now which makes sense..
is there a way i can test my o2 sensors i saw something about a blow torch and a volt meter?
