P0420 Outlander 2016 4N14
Hi forum,
Got a P0420 recently 150,000km Diesel 4N14. Tried Cataclean m, checked throttle body hose and hose after air box both look ok. Have an ELM scanner with car scanner pro…. What should I be looking for to diagnose the issue? I read about monitoring voltages on O2 sensors, but scanner software doesn’t seem to support, but I may be able to add PID to scanner, if someone knows them…. Thanks
