I pulled ny records from the dealership and found that the engine light was on before we did the second 30,000 tune up. The engine codes at that time were different. They were p1117, p1121. This shows on the code chart o2 sensor issues low threshold behind the cats. The notes said fix connections and light went out with no more codes. I wonder if its still an o2 sensor issue and since its on both sides, how could I test?
