It doesn’t happen again for days or weeks. With an intermittent code like that, is it likely the seal on the sensor periodically leaking and just replace the sensor or do you guys think it could be pointing to something else? Thank you.
If the sensor have gone you should hear the vacuum pump buzz (left side engine bay), if not I'd assume its something else maybe the pump itself.

As a side note my pump buzz around for a bit more since I changed the fluid couple of years ago (and yes, over spilled...). Bought a cheap sensor after reading this post, never got worse so haven't got around to change it.
