If you are encountering a P2195 error code, this guide will provide you with four practical DIY solutions to fix the issue at home.
The error code P2195 indicates that the engine could be running lean or that there is a fault in the air-fuel oxygen sensor.
Method A: Fuel Injectors
Inspect the fuel injectors mounted in the intake manifold for any leaks. When replacing the fuel injectors, ensure that the new injector has new seals to prevent leaking. It is advisable to change all the fuel injectors as a set to maintain even engine performance.
Method B: Exhaust Leaks
For small exhaust leaks, use exhaust putty to seal the leaking area. If there is a welded seam causing the leak, apply heat wrap around the area to make a permanent fix.
Method C: The MAF Sensor
Carefully remove the MAF sensor located between the air filter and the throttle body. Clean the wire inside using MAF sensor cleaner and reinstall it back in the car.
Method D: The Oxygen Sensor
Inspect the oxygen sensor’s electrical connections, wire harness, and metal tabs for damages. If any damages are found, replace the oxygen sensor.
After applying these solutions, use a diagnostic tool to clear the error code and ensure that everything is functioning properly with your vehicle.
