Bosch Oxygen Sensor
Posted: Fri Oct 09, 2020 11:44 am
My CEL comes on every once in awhile then goes off the next day. Three weeks later it repeats the pattern. Yesterday I plugged in my code reader and got a P1117 oxygen sensor heating read out in the error code. I've gone on-line and see Bosch makes two sensors for my 01 C4 Cab, a # 15250 downstream and a # 13564 upstream. I don't want to order the wrong sensor. Anyone out there know the correct one ?
