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
signal wire |

[secondary]
[o2
sensor]
[input]

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.)
