A P2195 code on a Ford F150 indicates that the oxygen sensor is detecting a lean condition in the engine. Specifically, this code refers to “Oxygen Sensor Signal Biased/Stuck Lean Bank 1 Sensor 1.”
P2195 code on a Ford F150
This means that the oxygen sensor before the catalytic converter on the side of the engine with cylinder #1 is providing a signal that suggests a lean mixture of fuel and air.
A lean mixture can be caused by various factors, such as:
- Vacuum leaks: Check for any damaged or disconnected vacuum hoses, intake manifold gasket leaks, or any other source of un-metered air entering the engine.
- Faulty oxygen sensor: The oxygen sensor itself might be malfunctioning. You may need to replace it if it’s not providing accurate readings.
- Faulty mass air flow (MAF) sensor: The MAF sensor could be providing incorrect readings, causing the engine to run lean. Clean or replace the sensor if needed.
- Low fuel pressure: A failing fuel pump, clogged fuel filter, or malfunctioning fuel pressure regulator can cause low fuel pressure and a lean condition.
- Dirty or clogged fuel injectors: Poorly functioning injectors may not deliver enough fuel to the cylinders, causing a lean condition. Clean or replace the injectors if needed.
- Exhaust leaks: Leaks before the oxygen sensor can cause incorrect readings. Inspect the exhaust system for any leaks and repair as necessary.
- PCV valve or hose problems: A stuck-open PCV valve or a damaged PCV hose can cause a vacuum leak and lead to a lean condition. Inspect and replace the PCV valve or hose if needed.
To diagnose and fix the problem, use an OBD-II scanner to read the stored codes and examine live data from the oxygen sensor. Based on the findings, you can proceed with the appropriate repairs. After completing the repairs, be sure to clear the code and verify that the issue is resolved.

P2195 code on a Ford F150 Tech Note
When diagnosing a P2195 code (Oxygen Sensor Signal Biased/Stuck Lean Bank 1 Sensor 1) on a Ford F150, it is important to consider the following tips:
- Start by checking for technical service bulletins (TSBs) related to this code, as there may be a known issue or an updated calibration for the engine control module (ECM) that addresses the problem.
- Always inspect for vacuum leaks first, as they are a common cause of a lean condition. Use a smoke machine or propane to detect leaks around the intake manifold, vacuum hoses, and other components.
- Perform a visual inspection of the wiring and connectors for the oxygen sensor, MAF sensor, and other related components. Damaged wiring or corroded connectors can cause incorrect sensor readings.
- Use an OBD-II scanner to observe live data from the oxygen sensor and MAF sensor. This can help identify any sensor-related issues or confirm the lean condition.
- Before replacing any components, try cleaning the MAF sensor with a proper MAF sensor cleaner. Sometimes, a dirty sensor can cause incorrect readings, leading to a lean condition.
- If the fuel pressure is found to be low, inspect the fuel system components, such as the fuel pump, fuel filter, and fuel pressure regulator.
- When replacing an oxygen sensor, be sure to use an OEM or high-quality aftermarket part. Low-quality sensors may not provide accurate readings and can lead to recurring issues.
Remember to clear the trouble code after completing the repairs and perform a test drive to verify that the issue has been resolved. If the code returns, continue with further diagnostics as needed.

P2195 code on a Ford F150 description
A P2195 code on a Ford F150 refers to an issue with the oxygen sensor, specifically “Oxygen Sensor Signal Biased/Stuck Lean Bank 1 Sensor 1.”
This diagnostic trouble code (DTC) indicates that the oxygen sensor located before the catalytic converter on the side of the engine containing cylinder #1 is detecting a lean air-fuel mixture.
A lean condition means that there is more air than fuel in the combustion chamber, which can lead to poor engine performance, decreased fuel efficiency, and potential damage to the engine.
Causes for a lean condition can include vacuum leaks, a faulty oxygen sensor, problems with the mass air flow (MAF) sensor, low fuel pressure, clogged or dirty fuel injectors, exhaust leaks, or issues with the PCV valve or hose.
To diagnose and resolve a P2195 code, it’s essential to use an OBD-II scanner to read stored codes, examine live data from the oxygen sensor and MAF sensor, and inspect the vehicle for any visible issues. Based on the diagnostic findings, perform the necessary repairs, clear the code, and verify that the issue is resolved.
