need help ,two or one O2 sensors
Does B16a1(jdm),cable tran. has two or one O2 sensor(s)?? The motor that I got has grey plugs on the wiring harnest(is it obd1?) and with one loom for O2 sensor(s). The loom has 4 wires.
Does this motor uses one O2 with 4wires, or 2 O2 sensors with two wires.  Calling all B16 wizards!!!!

yes it has two, and the only way to make that check engine light go off is to plumb you header for two and run them both, i had the same prob with my crx w/ b16a

The first gen JDM NON-OBD B16A uses 2 SINGLE wire O2 sensors. I have heard of people getting a heated 4 wire O2 sensor off of like a Del Sol VTEC (B16A3) when they get an aftermarket header like DC sports(they only have 1 O2 sensor flange). The knock sensor (code 23 i belive on the PR3) uses ONE wire.

is it 1st gen. or 2nd????????????
 Is it posible that I got 2nd gen.B16 with cable trans? I read on http://tech.hybridgarage.com/ that some of the differences between 1st and 2nd gen b16's(besides transmissions and OBD's) are:1st gen has Milky white connectors 2nd gen. hasGrey connectors Twin single wire O2 sensors One 4-wire O2 sensor The motor that I got has grey connectors, it has 4 wires for O2 sensor but it came with YS1 cable trans. On the tech.hybridgarage.com they also said that 2nd gen. hasMAP sensor as an integral part of the throttle body, not an external one with a tube. But my motor has throtelbody without MAP sensor,it has a tube. I'm waiting for PR3,OBD0 ecu which I recently ordered. If the motor is 2nd gen(I just don't know how it got cable trans.) can I use that commputer? Oh.. One more thing: my motor has a broken sensor which is located on the firewall-side of the motor, all the way by the head. As I understand it is a knok sensor, but it has two wires!!! At this point I'm completely confused :huh: Thanks to everybody for replys

From what it looks like, I got 2nd gen. B16a with ys1 transmission. I don't know how (I paid $1200 for it) but 170 horses sure is better then 160.Can anybody think of a posible explonation or a theory on how I got this motor with cable transmission?
P.S. If anyone is interested, I got it from PARSA Trading Co.,L.L.C. (888) 427-0336
