Hello, I hava a 2002 Accord SE with a 2.3L ULEV engine. The first o2 sensor plug was accidentally ripped from the wiring to the ECU. I am having a very hard time finding a proper diagram that shows which wire to connect where. I have even been to a junk yard and found a couple different accords, but the wire coloring was different than mine.

Can someone please help me?

 

The engine wire harness to the air/fuel ratio sensor are the following:

• ECM/PCM Connector C, terminal no. 18 - Grn/Blk wire (Sensor Ground) to AFR sensor male terminal no. 1
• ECM/PCM, Connector C, terminal no. 16 - Wht wire (Sensor Input) to AFR sensor terminal male no. 2
• ECM/PCM, Connector C, terminal no. 1 - Blk/Wht (Heater Control) to AFR sensor terminal male no. 3
• Driver's under-dash Fuse No. 6 (15A), Blk/Yel wire (IG power) to AFR sesnor terminal male no. 4

ECM/PCM Connector C is a 32-P Blue connector.

Hey thank you for your response. I just got a chance check it out. This "female connector wiring" is exactly what I was looking for, but my wires were not light green and white. Instead they were red and blue, with the 2 black. Do you happen to know which one goes where?

Cheers!

 

Wire at terminal 1 male goes to wire at terminal 1 female; wire at terminal 2 male to wire at terminal 2 female; etc., etc.

For example: Terminal 1 Grn/Blk wire to terminal 1 Lt. Grn wire. Terminal 2 Wht wire to terminal 2 Wht wire.

You would use the same logic for the color wires at the respective terminal numbers for the sensor you have.
