Official technical diagnostic wire for fault code P2195 specifically affecting Kia vehicles (K5, Telluride, Sportage, Sorento, EV6).
Select Your Kia Model for P2195:
1. Common Symptoms on Kia Vehicles
When Kia Engine Control Modules (ECM) trigger fault code P2195, drivers typically report:
2. Root Causes on Kia Engines
Historical diagnostic claims across Kia engines point to the following failure distribution:
3. Step-by-Step Fix Protocol for Kia
Check exhaust manifold near Bank 1 Sensor 1 for cracks or blown gaskets sucking in fresh air. on Kia engines.
Check B1S1 AFR sensor output. On Toyota/Lexus, 3.3V is stoichiometric; a sensor stuck at 4.0V+ indicates lean bias. on Kia engines.
Briefly spray unlit propane into intake. If sensor voltage does not quickly drop rich, the sensor element is poisoned. on Kia engines.
Install a new genuine OEM Denso / Bosch upstream A/F sensor. on Kia engines.
Clear DTCs, reset ECU learned trims, and road test. on Kia engines.

4. Kia P2195 Frequently Asked Questions
What does code P2195 mean on a Kia?
On Kia vehicles, P2195 indicates that the Engine Control Module (ECM) detected o2 sensor signal biased / stuck lean (bank 1 sensor 1). This typically points to Contaminated or failing upstream Air-Fuel Ratio (AFR) / O2 sensor or Exhaust manifold crack or gasket leak before the sensor.
Can I continue driving my Kia with code P2195?
Caution. ECU may over-enrich fuel mixture trying to compensate for a falsely reported lean signal. Because this code carries a High severity rating on Kia powertrains, we recommend scanning live data values promptly to prevent secondary damage.
How much does it cost to fix code P2195 on a Kia?
Estimated DIY parts cost ranges from $150 - $450 (DIY: $60 - $180), while professional shop repairs at an authorized Kia dealership or independent specialist typically range from $180 to $380 including diagnostic labor.
