Code P2195 Jeep Description

The P2195 Jeep code indicates a problem with the O2 sensor heater circuit in the vehicle. The O2 sensor, also known as the oxygen sensor, is responsible for monitoring the oxygen levels in the exhaust gases and providing feedback to the engine control module (ECM) to adjust the air-fuel mixture for optimal combustion. The heater circuit in the O2 sensor is designed to bring the sensor up to operating temperature quickly to improve accuracy and efficiency.
