Code P2098 indicates that the post-catalyst fuel trim system is too lean on Bank 2. This suggests that the oxygen sensor is detecting too little fuel in the exhaust mixture, which could impact the engine's efficiency.

Symptoms of code P2098 may include a decrease in fuel efficiency, rough idling, engine misfires, and a noticeable lack of power. The check engine light will also illuminate.

Possible causes for P2098 include faulty oxygen sensors, exhaust leaks, faulty fuel injectors, a malfunctioning mass air flow sensor, or issues with the fuel pressure.

To fix code P2098, start by checking for any leaks in the exhaust system. Replace faulty oxygen sensors, inspect and replace damaged fuel injectors if necessary, and ensure the mass air flow sensor is clean and functioning properly.

While you can drive with code P2098, it is not recommended for long periods as it can lead to further engine damage and decreased performance. It is advisable to address the issue as soon as possible.

After repairs, clear the code with an OBDII scanner and drive the vehicle for a period to see if the check engine light returns. If the light stays off and the vehicle performs well, the issue is likely resolved.

Yes, a P2098 code can definitely affect fuel economy. Since the code indicates a lean fuel mixture, your engine may compensate by using more fuel, thus decreasing overall fuel efficiency.

To diagnose code P2098, you will need an OBDII scanner to read the code and monitor live data. Additionally, tools for checking for leaks in the exhaust system and testing fuel pressure might be necessary.
