Toyota ...As oxygen storage capacity decreases, the heated oxygen sensor 2 switching frequency will increase. When the frequency ratio of heated oxygen sensors 1 and 2 approaches a specified limit value, the three way catalyst malfunction is diagnosed. P0430 2010 Nissan Pathfinder Code - Catalyst System Efficiency Below Threshold Bank 2P0430: Catalyst System Efficiency Below ThresThe exact definition for the P0430 code is “Catalyst System Efficienc As mentioned earlier, the P0430 is a diagnostic trouble code which means Catalyst System Efficiency Below Threshold (Bank 2). This diagnostic trouble code is stored when the ECU or engine control unit has detected that your car's catalytic converter is performing below the threshold that it is supposed to be operating at. P0420: Catalyst System Efficiency Below Threshold As oxygen storage capacity decreases, the heated oxygen sensor 2 switching frequency will increase. When the frequency ratio of heated oxygen sensors 1 and 2 approaches a specified limit value, the three way catalyst malfunction is diagnosed. P0430 Infiniti Code - Catalyst System Efficiency Below Threshold Bank 2P0430 is generic (has the same meaning for all vehicles made in 1996+) OBDII trouble code. Here's the technical definition for your Chevy Captiva: P0430: Catalyst System Efficiency Below Threshold (Bank 2) Catalyst System Efficiency.

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.12 posts · Joined 2023. #1 · Apr 8, 2024. P0430 Catalyst System Efficiency Below Threshold (Bank 2).".
