Code P0430 Lexus Description. The Engine Control Module (ECM) uses sensors mounted in front of and behind the Three-Way Catalytic Converter (TWC) to monitor its efficiency. The first sensor, the air-fuel ratio sensor, sends pre-catalyst information to the ECM. The second sensor, the heated oxygen sensor, sends post-catalyst information to the ECM. A code P0420 may mean that one or more of the following has happened: Leaded fuel was used where unleaded was called for (unlikely) A damaged or failed oxygen / O2 sensor. Downstream oxygen sensor (HO2S) wiring damaged or connected improperly. The engine coolant temperature sensor is not working properly. Tech Notes. The P0441 code means that the control module has detected a leak in the Evaporative Emission (EVAP). A loose fuel tank filler gas cap is the most common cause that triggers the P0441 code. ⚠ Check if your Lexus have Safety Recalls.Normally you can get by with just replacing the one at the rear of the exhaust.
