Would oil pressure sensor be easy to replace.
For me, yes. For you? I have no idea! For a professional mechanic, easy.
My daughters 2001 wasn’t typical. It was just behind power steering pump. If I remember correctly which isn’t often, there was some kind of bypass thing to it that made it suseptable to break something upon removal. With a hoist it would be considerably easier to access.
The last 300M was in 2004. Did you mean 2003 maybe?
