As a result, the upstream and downstream oxygen sensors’ studying would be the identical, triggering P0420. Watch out for the following symptoms to establish a fault catalytic converter.
Code P0420 can either be caused by a foul catalytic converter with very low efficiency or simply a Phony alarm brought on by a sensor such as the downstream or upstream oxygen sensor. It can also be attributable to internal oil leaks that induce the catalyst to clog up, that may lead to decreased performance.
