o2 sensor question...kinda urgent
Hello fellow civic owners,
I have a 05 honda civic lx 4dr. I recently bought an aftermarket exhaust with the proper placements for my two (2) o2 sensors. However, my engine light came on. I know it is because the second sensor is relaying bad oxygen messages to my ECU. I purchased an o2 simulator, but I do not know which o2 sensor to put it on. It tells me to put it on the rear sensor. Okay, so i go to the one after the cat, under the car, unhook it, and im ready. I notice that the wire colors do not match up according to the directions. Unfortunately the wires to the o2 sensor inside my headers, which I thought was my front sensor, does have the same color scheme as my o2 simulator. I am 100% certain that the actual sensors are in the right spot, meaning I didn't flip flop them when re-installing my new H/E. So, my question is: Which sensor is the rear and which senseor is the front because if the "rear" sensor is the one under or after the cat, then im %^&* because I don't know which wire(s) to splice.
A little more information is the o2 simulator has 2 wires: green and white.
My sensor going into my headers has 4 wires: 2 black, 1 white, 1 green.
My sensor underneath the vehicle has 4 wires: 2 white, 1 grey, 1 black.
My direction manual for the o2 simulator tells me to splice into the sensor with: 2 black, 1 white, 1 green.
I hope you can see my confusion and help me out.
Thanks!
