P0054a Ford - what does this mean? 2011 F-150 3.5 eco

Question

Do you have an idea of what does this mean or what the fix might be for engine code PO054a? This code was read from and Advance Auto parts scanner. I have no drivability issues at this time. Could be coincidence but, I got the truck washed the day before. 2011 F-150 3.5 eco

Answer 1

its possible water went into the oxygen sensor connector on Bank 1 Sensor 2. 

Did you hose down the buttom of the car also? I would use electrical parts cleaner to clean the connector and hopefully it the light wont come back
