ive got a obd1 b16a sir2 thats throwing a o2 sensor code. ive read things about b16's having two o2 sensors. is this true for all or just the obd0 ones? ive looked but i only see one 4 wire sensor in front of the cat. i looked on autozone and saw it was like $124, id hate to have to buy 2 of those. is there any other place i can get one for cheaper? thanks

 

sparkplugs.com have them for 42 i think plus shipping and they have oem denso and ntks

 

cool man thanks. anyone know if tyhe sir2 has 1 or 2 o2 sensors?

 

ok now which one?

if your car's a 91, and you've converted to obd1, you will have only 1 O2 sensor.
if this is the case, just get the first one, as you probably aren't using the oem connector from a 2000 si anyways. if you are using the 2000 si connector, get the third one.
this is under the assumption that the vehicle is a 91 converted to obd1

 

Na the car is a 92 da with a 93 b16a in it. Ive never seen a second sonsor behind the cat so i dont think i have 2, but how em i supposed to know wether it has the oem si connector or not? ive never had to change an o2 sensor on a motor swap before so this is why im confused...

 

Its got 1 O2 sensor. '92 Integras were already OBD1 so you wont have any issues with it plugging in.

 

ohhhh ok, i didnt know they were already obd1, i learn something new everyday. alright so ill just order the first one and it should work. thanks
