Default P1170
Have anyone of you found the solution to this code related to a broken weld on the passenger cat ?
Im still getting this code and previous owner replaced all 02 sensors
I guess I'll have to get under there to check the welds

Check the connections or replace O2 sensor. They go bad

- Exhaust Leak
- Faulty LH Bank Front O2 sensor
- LH Bank Front harness is open or shorted
- LH Bank Front circuit poor electrical connection
Faulty LH Bank Front HO2S LH Bank Front HO2S harness is open or shorted LH Bank Front HO2S circuit poor electrical connection

yes, drivers side was cracked almost all the way around. Had a local shop weld it back up and have not had an issue since. But, rule out all the other stuff first
