P013A Code 2013 Expedition EL

[superdave83]

Check engine light just came on for my 2013 EL 5.4L 3V, P013A O2 Sensor Slow Response - Rich to Lean Bank 1 Sensor 2. Anyone had any experience with this code with their 3rd generation? I was thinking to just replace the downstream sensor is the best guess to fix. However I did see that potentially the fuel injectors might have something to do with it. My scanner says the likely problem is an exhaust leak. Any advice is appreciated.

I had the same issue with our 2015, but bank 2 sensor 2. I bought the sensor and then checked the scanner again and the code was gone and no engine light. I guess that is what is meant by "slow response".

Good to know. Do you remember which brand of sensor you bought? I am guessing Motorcraft would work best, but people also tend to have good experience with Denso brand. Thank you for the reply Mjhcobra
