how many o2 sensors do s14 240sx’s have, i called the guy at nissan he said one, i read on the internet it has 2.
what year? OBD 1 and 2 were available on S14’s.
Different emissions reulations
Early 95’s have 1 while some late 95’s have 2 O2 sensors, 96’s an onwards had to have 2.
Just look at the downpipe and after the car. For sure there’s going to be one on your downpipe, that’s your pre-cat, then, if you’ve got an OBD2 setup, there should be another one after the cat, called the downstream O2 sensor
well my old exhaust only had one connected to the downpipe and now this new one has 2. so i’m tinking to just cover it with a peice of metal or put a bolt in.
there is two, one on the manifold one on the downpipe, urs is missing downpipe one…
wat dj infiniti said. but only one on manifold matters.
