97 Civic with a JDM D15B using a P2P ECU..

Only throwing one code -

PO141
02 Sensor Heater
Circuit Malfunction
Bank 1 Sensor 2

NO REAR 02 SENSOR PLUG..

I found the 02 sensor behind the dash and a few cut wires,,

I need to know which wires go where..



unwrapped the plugs going into ECU and this is what I found, no idea what these connections were trying to accomplish..



They were spliced into those brown wires which went straight to the 02 sensor.. but was cut from sensor and taped



These 3 plgs were just sitting behind the console. The middle plug is taped with some silver stuff and it feels like they are jumpers into plug. Car is a A/T converted M/T. i was thinking it was something for the A/T Shifter.

I have read this--> https://honda-tech.com/forums/honda-civic-del-sol-1992-2000-1/how-wiring-secondary-o2-sensor-directly-ecu-2509133/ and it did not have a concrete answer..

Thank You!

 

center plug - auto shifter plug - ignore

ECU wires - those blue things cause more problems than a fat guy on a little bike.
Plug A
blue - not sure what this is. do you know which point it runs to?
A5 - black/white - Secondary O2 heater control

Plug D
D11 - green/black - sensor ground (should be run to red/yel (D13) - sensor ground - a slightly different reference point which may make a difference it may not)
D14 - white/red - Secondary O2 signal

to wire one up use this to identify where each wire is located.

O2 heater (typically two black wires, can be two white wires, does not matter which it which)
black/yellow - ignition 12V - located at the main relay or under the hood in many places.
A5 - black/white - heater control

O2 signal (typically two different wire colors, can be green & black or white & green depending on which O2 you have)
D14 - white/red - O2 signal
D13 - red/yellow - O2 ground

 

Gracias,

I will be soldering and heat shrinking all connections this evening..
