Code P2195 2017 Toyota RAV4 Description
The P2195 diagnostic trouble code (DTC) for a 2017 Toyota RAV4 indicates that the Oxygen Air/Fuel Sensor Signal is stuck lean on Bank 1 Sensor 1. This means that the oxygen sensor located in the exhaust system before the catalytic converter is detecting a consistently lean air/fuel mixture in the exhaust gases. The Engine Control Module (ECM) uses this sensor's data to adjust the air/fuel ratio for optimal combustion. When the sensor signal is stuck lean, it means that the ECM is receiving a signal indicating an excess of oxygen in the exhaust gases, which can lead to a fuel mixture that is too lean.
Common Causes of P2195 2017 Toyota RAV4
- Faulty oxygen sensor
- Vacuum leak in the intake system
- Fuel delivery problem
- Issue with the Engine Control Module (ECM)
- Exhaust system leak
Symptoms of P2195 2017 Toyota RAV4
- Reduced fuel efficiency
- Rough idling or stalling
- Hesitation or stumbling during acceleration
- Check Engine Light illuminated

Frequently Asked Questions about P2195 2017 Toyota RAV4 Code
1. What does code P2195 mean on a 2017 Toyota RAV4?
P2195 indicates that the oxygen or air/fuel ratio sensor for Bank 1 Sensor 1 is stuck in a lean condition, meaning the engine is running with too much air or not enough fuel.
2. What are the symptoms of code P2195 on a Toyota RAV4?
Common symptoms include poor fuel economy, rough idling, hesitation during acceleration, and the check engine light turning on.
3. What causes the P2195 code on a 2017 Toyota RAV4?
Possible causes include a faulty air/fuel ratio sensor, vacuum leaks, exhaust leaks near the sensor, a clogged fuel injector, or a malfunctioning mass airflow (MAF) sensor.
4. How do I fix the P2195 code on my Toyota RAV4?
Repairs may involve replacing the faulty air/fuel ratio sensor, repairing vacuum or exhaust leaks, cleaning or replacing the MAF sensor, or addressing fuel delivery issues.
5. Is it safe to drive a 2017 Toyota RAV4 with code P2195?
While the vehicle may still be drivable, extended operation with this code can lead to poor engine performance, increased emissions, and potential damage to the catalytic converter.
6. Which sensor is affected by the P2195 code on a Toyota RAV4?
The code refers to the air/fuel ratio sensor located on Bank 1, Sensor 1, which is typically upstream of the catalytic converter on the side of the engine with cylinder #1.
7. Can a dirty air filter cause code P2195 on a Toyota RAV4?
Yes, a clogged air filter can restrict airflow and potentially contribute to a lean condition, which may trigger the P2195 code.
8. How much does it cost to fix the P2195 code on a 2017 Toyota RAV4?
Repair costs can vary, but replacing an air/fuel ratio sensor typically costs between $200 and $400, depending on labor rates and part quality.
9. Can a bad fuel pump cause the P2195 code?
Yes, a malfunctioning fuel pump can reduce fuel delivery, leading to a lean condition and triggering the P2195 code.
10. How do I diagnose the P2195 code on a Toyota RAV4?
Diagnosis involves using an OBDII scanner to confirm the code, inspecting the air/fuel ratio sensor, checking for vacuum or exhaust leaks, and testing the fuel and air intake systems.
