before you jump into conclusion, please understand that I have a 94 gsr chasis with 97 ls engine. Yestoday when I was insalling my catback I took off of the catalyst converstor and I found an o2 sensor, that has been cut. That's funny because I thoguht obd2 have 2 o2 sensor, one on the cat and one on the exhaust manifold. The one on exhaust manifold is intact, I tried to look for the other o2 sensor or signs of its prior existance but I couldn't find it. So do I have obd1 or obd2?

 

Is your check engine light on?

 

yea if your not throwing a cel i'd say you have a obd1 btw what ecu are you running?

 

cel is not on or I'd already know the answer

how do I check the ecu model? do I have to pull it out and give you guys the model number such as p28?

 

Exactly. Read the number off the ecu and let us know.

Hope that helps

 

I think 97 LS engine is a obdII. I have an 1996 GSR obdII, my o2 sensors are both on the cat- convertor. Are you using your cat back from your 94 gsr? I believe those are obdI.

 

this will sound dumb but where is the ecu? i tried to locate it it under the dash, but I've only found cruise control, is it right behind the fuses? if so it doesn't look easy to remove

 

the ecu is located on the passanger side, its right around the kick panel, peal back the carpet, youll see it

 

gay, the accords' are on the driver side so I thought integra wouldn't be too far off, I'll check tommorow.

 

where under the dash is the cruise control unit?

 

your list is wrong, 92-93 non-vtec tegs are obd1 pr4's

 

far left of the driver's dash, I'd say it's behind the latch for the trunk, mine is light blue.

 

that site looks just like HT

 

they have vB

 

you have obd1 trust me.you have obd1 injectors,distributor,harness,and ecu which is allowing you to use the obd2 motor.

 

I located the ecu and the middle number reads p75, which is an obd2 b18b1 ecu.

Well, where is my 2nd o2 sensor?! How come I am not throwing any CEL?
