I got my car a few months ago and it has had a small oil leak. I have found where the leak is coming from but I have no idea what it is so I’ve been unable to fix it. It’s coming from just above the oil filter and it has a blue wire running out of it. I’ve tried unplugging the wire but that didn’t do anything. Would anyone have an idea of what it could be?

 

Sounds like the oil pressure switch, fairly inexpensive at Repco

 

Hey! Thanks for the response. I managed to get a photo just to make sure I get the right part.

 

I'm not sure that looks like the oil pressure switch.

I would contact a Mazda dealer and get confirmation from them.

 

Okay I'll do that. Thank you for the help.

 

Hey Harley did you end up finding out what this part was? I’m having the same problem you are... Cheers

 

Hey there, I haven’t had managed to get it into Mazda yet as they were booked and works been busy, I did take it to a different mechanic and they said their best guess is a knock sensor so I ordered one and I’m going to try that when it comes
