3. Step-by-Step DIY Repair Guide for Chrysler 300
Check exhaust manifold near Bank 1 Sensor 1 for cracks or blown gaskets sucking in fresh air. on the Chrysler 300 equipped with 3.6L Pentastar V6 (292HP) / 5.7L / 6.4L 392 HEMI V8 (485HP SRT8).
Check B1S1 AFR sensor output. On Toyota/Lexus, 3.3V is stoichiometric; a sensor stuck at 4.0V+ indicates lean bias. on the Chrysler 300 equipped with 3.6L Pentastar V6 (292HP) / 5.7L / 6.4L 392 HEMI V8 (485HP SRT8).
Briefly spray unlit propane into intake. If sensor voltage does not quickly drop rich, the sensor element is poisoned. on the Chrysler 300 equipped with 3.6L Pentastar V6 (292HP) / 5.7L / 6.4L 392 HEMI V8 (485HP SRT8).
Install a new genuine OEM Denso / Bosch upstream A/F sensor. on the Chrysler 300 equipped with 3.6L Pentastar V6 (292HP) / 5.7L / 6.4L 392 HEMI V8 (485HP SRT8).
Clear DTCs, reset ECU learned trims, and road test. on the Chrysler 300 equipped with 3.6L Pentastar V6 (292HP) / 5.7L / 6.4L 392 HEMI V8 (485HP SRT8).

4. Chrysler 300 P2195 FAQs
What causes code P2195 to trigger on a Chrysler 300?
On the Chrysler 300 (3.6L Pentastar V6 (292HP) / 5.7L / 6.4L 392 HEMI V8 (485HP SRT8)), P2195 is most frequently caused by Contaminated or failing upstream Air-Fuel Ratio (AFR) / O2 sensor or Exhaust manifold crack or gasket leak before the sensor.
Where is the OBD-II port located on my Chrysler 300?
On the Chrysler 300, the 16-pin DLC diagnostic connector is located Under driver side dash near left knee panel. Plug in any standard OBD-II scanner with the ignition in the ON position to read freeze-frame parameters.
Can I safely drive my Chrysler 300 with code P2195?
Caution. ECU may over-enrich fuel mixture trying to compensate for a falsely reported lean signal. Given that P2195 carries a High severity rating, we advise avoiding heavy towing or aggressive throttle inputs until sensor readings are verified.
