Mitsubishi Galant 2000 V6 OBDII Code P0135: How to Fix Engine Lamp Issue

Model: Mitsubishi Galant Fault Code: P0135 Posted: 2014-01-27 05:43

Hello, I own a 2000 Mitsubishi Galant with a 2.5L V6 engine (6A13 model). Recently, the engine warning light has been turning on repeatedly. Using an ELM327 OBDII scanner and ScanMaster-ELM software from WGSoft.de, I've identified the fault code as P0135. After clearing the code, it returns shortly after, indicating a persistent issue. The error refers to Bank 1 Sensor 1 — could someone please clarify where this sensor is located on my engine? Any advice or troubleshooting steps would be greatly appreciated.
