I got a handa civic 1993 hatchback dual carbi 1.5l change the o2 sensor on the headder but the light still on how can i turn it off, any special way to reset it, or it will turn off later, its been a day.

 

reset the ECU by pulling the 7.5A fuse in the engine bay fuse box and putting it back in after 5 minutes. pull codes and repost what comes up.

 

I installed a universal o2 sensor would that make a diffrence? I will remove the fuse and let u know how i went

 

I removed the fuse and the batterie negative for 15 min and still the
Light stayed on after reconnecting and starting. What do u think , is there more then one sensor? Or is it possible that it stayed on cuzni used a universall o2 sensor.

 

prolly not wired up right, or the 02 was bad from the start

 

what country you from?

also, did you read the code? did it say that your o2 was bad? you might have other issues besides your o2

 

Wait. Did the code present itself BEFORE you swapped out O2 sensors?

 

Im from australia the car is imported i put it on the jack today i saw that there a sensor or some sort of sensor in the middle of the exhaust underneath (right in the middle of the exhaust pipes underneath the car screwed to it the exhaust pipes with the wire cut of the top exactly) could that be the reason why the light is on?

 

If this is pretty much what you're talking about:


Then don't worry. It's just another o2 sensor. Replace that as well if you're sure that it is actually your o2 sensor.

To check your CEL code get a paperclip and use this page to check what is actually wrong with your car:

How to pull CEL codes

 

Thats exactly what im talking about also i tried to perform a cel code but couldnt find the the plug. And the phot u sent me is what im talking about but my installed sensor is cut from top i can change it but where should i connectit to?

 

JDM import? That's not a secondary O2 sensor, JDM cars had a temp sensor in the catalytic converter. If the cat overheats a light on the dash comes on (red light, looks like a catalytic converter with heat lines coming off it) or it's a second primary O2 sensor (OBD0 JDM B16As were setup like this, as well as older Preludes.

Cat temp sensor:



Twin primary O2 sensors:

 

Yes it is a import car, where does that temp or o2 sensor connect to? Can u take photo or show me a diagram that shows where it should connect to plz.

 

where can you get a sensor like such so that the light on my jdm eg cluster would function? (referring to the light that looks like a catalytic converter with slices of hot bacon on top of it")
