The smog shop found that the P1000 is because a rear O2 sensor isn't showing as ready.Realizing that I had a way to see the raw voltage signal, I grabbed my SCT handheld and watched the O2 sensor data live. 3 of 4 were showing >100mv and <990mv with plenty of jitter. The driver side rear O2 (Bank 2, Sensor 2) only shows >100mv when I'm at relatively high throttle angles and then wobbles around from 10-40mv and it spends a lot of time at 0mv. This indicated either a lazy O2 sensor or an intermittent short or a bad connection. I replaced the sensor and right out of the gate I was seeing >100mv for a minute during idle and driving but it quickly reverted to the prior behavior so I figure it's probably an intermittent short. The harness wrapping right at the end of the trans is in visibly good shape but the wrapping and the number of forks in the road make tracing the wire a bit of a yuk job... I don't want to unwrap anything I don't have to. I'm hoping someone can help me out with the path of where the relevant wires run or places where it/they is/are more vulnerable to damage than others. In a separate effort I've ordered some MIL eliminators which basically throw a small capacitor and a resistor inline to simulate the needed <1v signal as well as sufficient jitter in the signal for it to appear legit to the ECU. I don't know if this is guaranteed to get flagged by Kommiefornia's OBD2 scan (I already passed the visual) and I'm curious to know if any of you have concrete knowledge on the topic.</blockquote>
