Thank You Tizzy for the helpful information.
Driving my van over the weekend, the CEL reset itself. I drove it for almost 2 Days and then it popped up again. Same code but also this time got P0041 for Incorrect Purge Flow. I did smoke test it last week and had to replace the EGR Valve, then retested it and it is leak free. I am going to check that wiring for the heater on the upstream o2 sensor. Are there any correlations between these two codes?
