Hi All,

I am getting an P0024 code on Bank 2 and Service Engine Light is on. I have seen many posts leading me to believe a few things that could be the reason:

1. Delayed Oil Change (which is true in my case)
2. VTC(valve timing cover) replacement

I used a bluetooth OBD2 reader to monitor the live data and one thing I observed

1. @725 RPM the Long Term Fuel trim on Bank 2 is negative where all other fuel trim readings are positive.
2. @1687 RM all are positive including LTF Bank 2 (0.8% lowest of them all)
3. @2812 RPM everything else is positive except LTF Bank 2 which is - 0.8%

Not sure whether this means anything.

Also I wonder if there are other ways to troubleshoot to get to the root cause.

Any help is appreciated.

Thanks
