Hi there.

Most of the times, a short on the A/F sensor wiring results in a blown FI SUB fuse in under-the-hood fuse box (see attached graphic). Start by checking that fuse and then we can take it from there if need be.

Best Regards.

In case you were wondering, P0498 can also be caused by that same FI SUB fuse being blown.

Please let me know what you find.

Best Regards.
