Oil pressure sensor alert after oil change - solved for now

[aixelsyd]

Posting this incase my experience helps others. About 10 miles in after my break-in period oil change an oil pressure senor alert came up on my Bronco (2.7-liter V6 engine). I checked the oil and everything seemed fine. Restarted and the alert cleared and thought perhaps it was a bubble. About a week later it fired off again and this time I just had it towed to the dealer. I wasn't going to fool with it anymore. After the dealer checked it they determined it was the oil pressure sensor and replaced the sensor. The oil alert then fired off again about 20 miles after the replacement. Long story short on the next visit they found it was a bad O-ring.

Two weeks in now after the latest fix and I haven't had the oil pressure alert. I still am holding my breath on this but so far so good.

Which O-ring? Oil drain plug or oil filter canister?

Not that this is what happened to you. Just my two cents. There are a few o-rings on the filter that should be replaced during each oil change. It’s a step that some businesses and dealerships skip if they don’t look too bad. I always ask for the oil o-rings after mine is completed. Been doing it for years. Keeps people honest.

Dealer notes say oil filter housing O-ring broken.

This is the only real downside of a non-cartridge style oil filter housing. Loved the simplicity of removing the housing and swapping just the filter medium itself, but you have to ensure you change the housing o-ring on every change. Other OEM filter brands like Mann filter for BMW/MINI provide a housing o-ring with every filter.

Figured Motorcraft did the same -- feels like OP's change either didn't swap the o-ring or didn't properly oil them before reinstall?

The orings may have been changed but not seated properly. One could then have been cut when reassembled. Something to be mindful of.
