Hey any of you car guys have a good internet site for picking up an ECU for an older Nissan pickup I have?

Be careful swapping in ECUs. If it was a short, the new one will immediately blow out.
I've been getting an error on an 02 sensor, swapped the sensor and the error stays. I traced the wires and it doesn't appear to be any issues with the wire for as much as I could see.

How old? LKQ is a great source, I have one local, but they are online as well as ebay. But they only go back 15 years or so I think.

OK, so not a magic smoke problem.
I don't think so. I have a crackpot car guy who spent a few minutes on it and tested the voltages coming out of the computer to the o2 sensor and he said something wasn't right. He thought it was either wires or computer. I traced the wires and they look good.

I have a 1997 nissan pickup. I'm not sure if the comp is the same as the pathy but it might be. Thanks for the help.

Can't find this computer anywhere....part # MECM-B233

There is one on ebay but they are charging more than I can sell my truck for.

ROFL, it comes slightly lifted now. Well compared to my old high school 1987 nissan pickup. :)

Try resetting the ECU just before you go into inspection by removing the battery terminals, or slip the inspection guy a lil something something.
Bribery aside, they wouldn't pass me with two or more sensors set to "not ready" (which they all get set to when you reset the computer). Fortunately, my particular code was one that took a number of drive cycles to trigger, so the rest of the sensors went to ready except the problem one, I passed the inspection, and then my check engine light came on two days later :D
