Toyota fault code P2195 relates to a lean air/fuel mixture in bank 1.

OBD code P2195 for Toyota vehicles indicates that the O2 sensor signal stuck lean on bank 1 sensor 1. This means that the upstream oxygen sensor in bank 1 is reading a consistently lean airfuel mixture.

The Engine Control Module (ECM) triggers this code based on the feedback from the oxygen sensor.

The signal or system involved is the airfuel ratio control system, which monitors and adjusts the mixture of air and fuel entering the engine for optimal combustion.

Detailed information on Toyota fault code P2195, including symptoms, causes, and solutions.

To diagnose and fix OBDII code P2195 in a Toyota, start by checking the oxygen sensor (Bank 1 Sensor 1) voltage using a voltmeter.

Ensure the sensor is getting power and ground.

Next, inspect the wiring harness and connectors for any damage, corrosion, or loose connections.

Use a scan tool to monitor the sensor’s data and see if it responds correctly.

If the sensor readings are out of range, consider replacing the oxygen sensor.

Additionally, check for any exhaust leaks that could be affecting sensor performance.

Clear the code after making any repairs and test drive the vehicle to ensure the issue is resolved.
