Potential causes of a P2195 code include: Use a scan tool to get readings from the sensor, and monitor the short and long term fuel trim values and O2 sensor or Air Fuel Ratio sensor readings. Also, look …

Jan 7, 2023 · When your engine light comes on, the code P2195 may be to blame. Learn what this code means, the potential causes, and how to fix it.

What Does Code P2195 Mean? The P2195 code indicates that your powertrain control module (PCM) has detected that the oxygen sensor signals stuck lean for bank 1 sensor 1.

The P2195 code indicates that the oxygen sensor signal for Bank 1 Sensor 1 is biased or stuck lean. This means that the oxygen sensor is detecting a consistently lean air-to-fuel ratio in the exhaust …

Jun 13, 2024 · Typically, all you need to do to fix a P2195 engine code is to replace or clean the oxygen sensors. However, if that doesn’t fix your problem, check out the wiring.

Dec 9, 2024 · What does the P2195 code mean? The P2195 code indicates an issue with the oxygen sensor reading in your vehicle. Specifically, it refers to the first sensor located on Bank 1 of your …

So first things first, what does the code P2195 mean? The P2195 error code tells you that one of the sensors in the vehicle has detected a problem with the mixture of fuel and air.

What does a P2195 code indicate about my vehicle’s emissions? The code means the PCM has detected a persistently lean‑biased voltage from the upstream O₂ sensor on Bank 1.

Dec 25, 2025 · Decode P2195, the “stuck lean” trouble code. Learn the root causes (leaks, fuel issues) and follow step-by-step repair guidance.

Oct 10, 2018 · The P2195 code is a result of the engine control module (ECM) indicating that the oxygen sensor is fluctuating outside its optimal range. This specified range is characterized by a minimum of …
