Chrysler 200 2015-2017 Emissions & Sensors Specifications

The emissions sensors for the 2015-2017 Chrysler 200 are designed to be compatible with all trim levels and engine configurations, including the 2.4L Tigershark and 3.6L Pentastar engines. However, it is recommended to verify the specific part number with your vehicle's VIN to ensure compatibility, as minor variations may exist between model years or regions.

Emissions sensors in the 2015-2017 Chrysler 200 require minimal maintenance. Regularly inspect the sensors for damage or contamination, especially during oil changes or exhaust system checks. Ensure the engine is running efficiently, as poor combustion can lead to sensor fouling. Replace sensors as recommended by the manufacturer or if diagnostic trouble codes indicate a malfunction.

To replace emissions sensors, first, locate the faulty sensor (upstream or downstream). Disconnect the negative battery terminal for safety. Use an O2 sensor socket to remove the old sensor. Apply anti-seize compound to the threads of the new sensor, install it, and reconnect the electrical connector. Reconnect the battery and clear any diagnostic trouble codes using an OBD-II scanner.

If the check engine light is triggered, use an OBD-II scanner to retrieve the diagnostic trouble code (DTC). Common codes for emissions sensors include P0135 (O2 sensor heater circuit) or P0420 (catalyst efficiency). Inspect the sensor wiring for damage, check for exhaust leaks, and test the sensor's functionality. Replace the sensor if it fails testing or if the issue persists after troubleshooting.

To optimize emissions sensor performance, ensure your engine is properly tuned and running on high-quality fuel. Regularly replace air filters and spark plugs to maintain efficient combustion. Avoid using fuel additives that may contaminate the sensors. Periodically inspect the exhaust system for leaks, as they can affect sensor readings and overall emissions performance.
