Dealing with P0131 and P0030 codes. Did my research and found that this TSB should be done prior to replacing the O2 Sensor. Looks a bit more complicated than I'd like to get into (the crimping of the special pin, etc. Thinking I'd leave it to the dealer. Before I take it in, I'm wondering if there is anyway to tell if the TSB has already been done. The truck is Canadian spec. Not sure if the records would follow, or how I'd call FC Canada to find out?

If the TSB has been done, I'd grab the genuine o2 sensor and just have my local shop replace it. If it hasn't, I'd probably have the dealership do it all :-/
