P0131 Code: Easy Steps to Solve It
The P0131 trouble code is a diagnostic trouble code (DTC) that indicates a problem with the oxygen sensor circuit, specifically signaling low voltage from Bank 1, Sensor 1. This sensor plays a crucial role in monitoring the oxygen levels in the exhaust gases, allowing the engine control module (ECM) to adjust the air-fuel mixture for optimal combustion. When the ECM detects that the voltage from
