O2 sensors?

i have a 96 non-vtech honda civic. I have the engine with 2 O2 sensors. Well
i got new 4-2-1 headers and i only have 1 o2 sensor port. So i am running
check engine light because only 1 o2 sensor is plugged up. How can i get rid
of this problem? Or where should i put the other sensor??

 

where were they installed on the original exhaust?

 

Put the factory manifolds back on.

 

with 2 resistors, and a capacitor you can fool the computer into believing the
second sensor is installed

1 resistor (4-7 ohms 50 watts (have to check your service manual)) will
simulate the heater circuit

the capacitor 1uf 25v and second resistor (10-25k ohm 1/2 watt) will be fed off
the primary o2 sensor signal wire and will feed the secondary 02 sensor input


primary 02 ------[10-25k resistor]---.---[capacitor]------gnd

I hope this displays correctly

 

There's supposed to be one sensor ahead of the catalytic,and one after it.
OBDII standard.

(I believe he deleted the CAT.)

 

Is it necessary to simulate the heater?

 

Yeah, I know, I'm just fishin'.

You know.

 

well only if the original has a heated secondary o2 sensor. my 97 accord
v6 needed the heater bypass resistor, otherwise it threw a CEL

 

try installing automotive bulb no 194 (12Volt) in lieu of the resistor.
This will fool the ECM
