Can anyone tell me the location of the oil pressure sensor on a 2005 Impala LS (3.8L V6 VIN:K)? Or better yet, a diagram link that shows the location?

Also, should I drain the oil before replacing the sensor? I assume that oil might pour out of the sensor port during replacement.

thanks,

It is in the place that makes the most sense...within inches of the oil filter.

Item #431

Bookmark that website, they have tons of parts diagrams.


Oh...if you let the car sit a while, most of the oil will be in the pan with the exception of what's in the filter. I don't think you'll lose much oil if any when you pull the sensor out, but I haven't changed one yet so be prepared with a rag in case I'm wrong.

 

Thanks!

Swapped the sensor. Fingers crossed that it fixes the intermittent Low Oil Pressure light/alarm.

 

A lot easier than changing the pump. If you do that you will have to drain the oil and remove the pan to get to it.
