When I bought my engine and harness, the bank 2 front and rear o2 sensor wires were cut and I had no idea which ones went where. So I guessed and hooked them up. I was amazed that they worked. But I since deleted the rears and dont even have them in anymore. I put some pacesetters on. Since then, the bank 2 front is throwing a code and the only thing I could think is that I mixed up the wiring of front and rear and seeing that the rear isn't there anymore, its not getting the proper signals. I was wondering if anybody knew what pins on the pcm went to the bank 2 front and rear o2s. I'd appreciate it if you could shed some light on the subject. Thanks. Tim

 

Here you go:

Blue connector

PIN Wire Color Function
25 Tan HO2S Signal Low Bank 2 Sensor 2
26 Tan HO2S Signal Low Bank 2 Sensor 1
28 Tan/WHT HO2S Signal Low Bank 1 Sensor 2
29 Tan/WHT HO2S Signal Low Bank 1 Sensor 1
65 PPL HO2S Signal High Bank 2 Sensor 2
66 PPL HO2S Signal High Bank 2 Sensor 1
68 PPL/WHT HO2S Signal High Bank 1 Sensor 2
69 PPL/WHT HO2S Signal High Bank 1 Sensor 1

 

Thanks, your a life saver. Now I just have to try to trace them back to the pcm.
