2011 isx435 problem

[aalendar]

Thanks for reply, i will start with the sensors, then check further electric components and wires. Rarely, I do power wash engine and I did it 2 weeks ago.Maybe that was the cause.
Also first breakdown happened in Oklahoma on Sunday , literally in the middle of nowhere, and only guy willing to come was that young guy ( mechanic? ) Bill was $850 (originally $1000, i had to talk to owner ?) Mobile mechanic come out 50 miles to me plugged into computer, deleted codes and follo wed me 40 miles to Stratford tx, where he lives anyway I guess. All that for $850
Thanks
