41 Primary oxygen sensor heater

I was reading everywhere that I should just replace the O2 sensor but I have a D15B, only one 02 sensor is connected, the one in the header is unplugged. What should I do??

 

what ECU? the jdm d15b ECU has the 1wire o2 and your orig ECU should have 1 heated o2.

 

Im using my stock p28. 93 Si.

 

it should be exactly the same as before the swap...

 

my 02 sensor in the headers is not plugged. there is a socket hanging in the same area but it does not fit..

 

you should have a 4-wire o2 sensor from the old motor, plug that baby in.

i did this same exact swap before into my EX. you should use everything off the old motor, including the exhaust manifold.

 

im gonna go check to make sure i have everything.

 

OK. My 02 sensor has only 1 prong in it..hard to see cause of cell phone pic and the hanging socket has 4 prongs.

 

replace a new o2 sensor and u are good.that was what happened to me a week ago.the car received a 41 code CEL and replaced a newer o2 sensor (used but oem, plug and play) and the light goes away

 

is that 02 sensor JDM then?? it has only 1 prong.

the engine i am running now is JDM B16A SiR II but i am using USDM D16Z6 o2 sensor.it plugs right in and runs like a champ.to be honest with u.i dont remember if it is 1 prong or not but it is 4 wires designed

 

Try this

 

Ok well if the pic was bigger then you could actullay read it but it says check terminals on 02 side c-d for 10-40 ohms if not with in that range then replace then check for continuity to gound on both those terminals if so replace 02 sensor.

Let me pull out my magnify glass lol. Make it bigger

 

You need a 4 wire 02 sensor. its the wrong one.

 

damn now i have to buy a new 02 sensor with 4 wires. thanks guys. really appreciate the help.

does vtec not engage when there is an 02 problem??

 

JDM o2s have 1 wire
USDM o2's have four or five wires

Just replace ur JDM o2 with a USDM one. Then reset your ECU after you change the o2. The no more CEL's

It should, I had a o2 CEL and my vtec still worked

really?i thought my jdm has 4 wires..i will recheck when i get home tonight
i simply pulled the plugs on the jdm o2 sensor and replaced with a usdm o2 sensor and it works.

 

i havent pushed the car past 5500rpms yet. i always thought it was hard to hear a single cam engage.

when i was running a single cam (d16z6) before the swap (b16a), i always pushed it to 6500rpm but after the swap done(a week ago), i have not really test driven it hard yet.i was told to push b16a all the way to redline around (7200rpm)

 

why dont you have the original 4 wire o2 sensor from the original engine?

 

when i bought the car the motor was shot..so it was missing alot of things..including the sensor..i just checked.

 

Ok..i found a 02 sensor in my pile of crap, the problem now is i can get the O2 sensor out of the manifold. I dont want to force it out. Help??

 

Just find the right wrench and spray some PB Blaster on it, wait a few min and use a cheater bar and take it off.
