I ended up replacing the oil pressure sending unit and that corrected everything.

So I was checking the oil level with the electronic level, and I notice that the oil pressure gauge fluctuates with the engine off, what's up with that, I just got through driving about 15 minutes earlier and when I turned the key the engine compartment fan went on, not sure if those details mean anything.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

5 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

  • Rennlist: 1 discussions

0 evidence records excluded for query context · 0 excluded by outcome qualification · 0 adjusted by outcome qualification.

0 acknowledgements have no verified action link; they do not establish a repair result.

POST 1 / ORIGINAL POSTEROriginal post

So I was checking the oil level with the electronic level, and I notice that the oil pressure gauge fluctuates with the engine off, what's up with that, I just got through driving about 15 minutes earlier and when I turned the key the engine compartment fan went on, not sure if those details mean anything. Is this normal? Need a new oil pressure sending unit? When the engine is running it all points to normal readings with slight fluctuation here and there.

POST 2Original post

Most likely a bad oil pressure sensor. A healthy one will read 0 when the engine is off and a not so good one will read something non-zero but it still reads the pressure correctly when engine is on.

POST 3Original post

My oil pressure gauge was doing that. Sometimes it would read 1 with the engine off. After a while it started to fail periodically while driving (Oil Failure messages and the gauge would plunge to zero). The oil level was fine. I ended up replacing the oil pressure sending unit and that corrected everything. It's an $80 part and a fairly easy DIY project.
