P2097 Chevrolet Malibu: Exhaust Leaks and Oxygen Sensor Issues Explained

If you are getting a P2097 error code in your vehicle, don’t worry. This video will provide you with two practical solutions to fix the error code at home. The Zeus app can be used to scan your vehicle and identify the error code P2097, which indicates a fault with the post-catalyst fuel trim system being too rich in bank one.

Method A: Exhaust Leaks

The exhaust system of a vehicle starts at the engine combustion chambers and runs along the undercarriage, ending with a visible tailpipe. If you have a small leak, you can use exhaust putty to seal it up. First, clean the leaking area with sandpaper and a wet wipe to ensure better application. Stir the paste well to activate it, and then apply and press the paste to seal the leaking area. Let it cure for 2 to 24 hours, depending on the external temperature. You can use a hair dryer to speed up the curing process. Additionally, for a welded seam leak, use a heat wrap to make a permanent fix.

Method B: The Oxygen Sensor

The oxygen sensor, located before the catalytic converter, can cause the P2097 error code. Visually inspect the oxygen sensor’s electrical connections, wire harness, and metal tabs for any damages. If damages are found, it’s recommended to replace the oxygen sensor.

After applying these methods and fixing the issue, you can use the Zeus app to clear the error code and ensure that everything is fine with your vehicle.
