P2196 Chrysler Code - O2 Sensor Heater Circuit Fault

Quick Answer

The P2196 Chrysler code indicates a potential issue with the O2 sensor heater circuit in the vehicle's exhaust system. Common causes include Faulty O2 Sensor: The O2 sensor itself may be faulty, causing the heater circuit to malfunction, Wiring Issues: Damaged or corroded wiring connections to the O2 sensor can prevent the heater circuit from operating correctly, Blown Fuse: A blown fuse in the O2 sensor heater circuit can cause the P2196 code to trigger. Severity is Moderate - service should be scheduled soon. The vehicle may still be drivable for short trips if it runs normally, but avoid hard driving and repair it soon.

Code P2196 Chrysler Description

The P2196 Chrysler code indicates a potential issue with the O2 sensor heater circuit in the vehicle's exhaust system. The O2 sensor is responsible for measuring 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 is designed to bring the O2 sensor up to operating temperature quickly for accurate readings.
