2001 Nissan Maxima P0140, P1320, and P0430 Fault Codes - Engine Light & Slip/Trac Light On

My husband's 2001 Nissan Maxima is showing three persistent fault codes: P0140, P132-0, and P0430. The check engine light remains on continuously, and the slip/traction control light comes on intermittently—staying illuminated until the vehicle is turned off, then remaining off for a period of time before reappearing. We are seeking advice on what these codes mean and how to diagnose or fix them. Specifically: - P0140: Oxygen sensor failure in bank 1, sensor 2 (after catalytic converter) - P1320: Ignition system malfunction related to the engine control module - P0430: Catalytic converter efficiency below threshold for bank 2 These codes suggest potential issues with emissions systems and engine performance. We would appreciate guidance on whether a professional diagnosis or component replacement (such as oxygen sensors or catalytic converters) is needed, especially given the intermittent traction light behavior. Any insights from owners of 2001 Nissan Maxima with similar symptoms are greatly appreciated.
