Lexus IS: Replace Catalytic converter and P0420 still there

Sun, 15 Feb 2026 11:33:58 -0700

Hello there.

I own a 07 Lexus IS 250 AWD with 90k miles that replaced both bank 1 O2 sensors and also new cat converter but the ecm P0420 came back at 30 miles after driving.

I try this: 1. I disconnect the air fuel sensor before cat and drove the car and just one code came up P0051 (Why just this one and not the P0420)

Short term fuel trim on bank 1 is -2.3%
And long term fuel trim read -23.4%

I will appreciate all your help…
