okay here it is..... if im changing the oxygen sensor is it recommended to change the oxygen heater as well .. just dont know if its a good idea or not

 

if it's a heated o2 sensor, the heater is built in the o2 sensor itself

 

i got my o2 sensor and there another thing that looks the same beside it ???

 

don't know what you're talking about ..

But a heated o2 sensor has the heater built in and it usually 4wire,sometimes 5 wire..

And the unheated o2 sensor has 1 wire,and waits for the exhaust manifold to heat it up.

 

is that manifold a dual o2?? i have never heard of a the heater being seperate

 

thats strange i always thought there was 1 sensor but a looked a little more behind the ex manifold and saw another one beside it ... both sensors being both single wire.. if i had a diagram from a 90-91 teg that would probably show me somthing ... i tried looking it up on my service manual and all it says is oxygen sensor & oxygen sensor heater .. making it sound like 2 seperate peices .. i dont have an teg but i know its the donor car for my b16 swapped hatch

its a dual o2 sensor ex manifold like this one

it's not an o2 sensor and heater,,,its 2 seperate o2sensors,thats how the 1st gen b16a runs..they're NOT heated,they just heat up with the manifold..

heated o2 sensors have 4 or 5 wire.

 

duh! very clear now as i read on... thank you i must get myself 2 o2 sensors

 

im not throwing oxygen codes though from my ECU does this still mean they are still good ??? im guessing No cause when i did my Emission Testing my Hydro Carbons were outta the Roof..... so i assume this is my main problem
