Default o2 fault code questions
I checked my fault codes and got these two faults. If it doesnt say malfunction, do the o2 sensors have to be changed?? Car seems to be running fine..

I also have 031 block, but i dont really understand that stuff so its not very helpful to me ; )


17521 - Oxygen (Lambda) Sensor; B1 S1: Internal Resistance too High

P1113 - 35-10 - - - Intermittent


17539 - Oxygen (Lambda) Sensor; B2 S1: Internal Resistance too High

P1131 - 35-10 - - - Intermittent

TIA

How long before the codes come back, once you clear it?
