Code P2195 RAM Description

The P2195 diagnostic trouble code (DTC) indicates a fault in the O2 sensor heater circuit. The O2 sensor, also known as the oxygen sensor, is a crucial component in the exhaust system that measures the amount of oxygen in the exhaust gases. The heater circuit in the O2 sensor is responsible for quickly bringing the sensor up to operating temperature for more accurate readings. A fault in this circuit can lead to incorrect sensor readings, which can negatively impact the engine's performance and emissions control system.
