Out of the game for a minute
I recently got basically a steal of a deal on 93 eg sedan with b16a.(I had a nonobd b16a DA 6 years ago) i got it home and decided to jump the codes. It sent me 1,41 and 21 which i looked up and have some questions about it. The 1-41 are o2 related. It's got a hytech tri-y on it and i haven't even looked to see if the o2 is plugged in honestly but here is where I am trying to get some good info. It has a p30 ecu which I believe can be obd1 or 2. How can I tell. If it is obd 1 the test pipe shouldn't throw a code correct? So if it is obd2 the test pipe would cause a code but wouldn't it have different plugs than the body harness. The vtec code is most likely wiring I am going to guess but if that were the case wouldn't it have more vtec codes? Just looking for some points in the right direction. I did search just didn't find what I needed.

Re: Out of the game for a minute
u have an obd 1 ecu. the 02 can be a bad sensor or just a bad connection. i had an issue with mine, ended up just re-soldering the whole wiring harness and it went away. a test pipe should not throw a cel for an obd1 car.
