My 2016 LR4 SCV6, on a trip to Seattle, threw the check engine light. GAP tool reveals that it is the P0170 code, the bank 1 fuel trim. I cleared it and it immediately seems to come back on the GAP tool, although the CEL doesn’t come back on.
i vaguely remember that it might have to do with the charcoal canister, but a search here didn‘t find that. I do wonder a bit, because I recently filled the tank with a Gerry can, which obviously doesn’t have automatic shutoff. I listened for the telltale tone of the fuel coming up the neck and stopped it before it overflowed the neck, at least.
Does anyone have a suggestion as to where to start looking for a problem? Or should I just wait and see if the CEL comes back on on the trip back down to Portland from Seattle?
