Welcome to the site, check your wire connection to the knock sensor and the Evap purge valve.
I googled the codes and found several how to videos |
Just got this code po325 only which calls for the knock sensor has anyone replaced it? I cleared the code and start using 89 octane if the code comes back any tips on replacing it thanks

P0325 is related to the knock sensor and or the wiring to it.
Check the wire it could be loose , did you have the starter changed? The knock sensor lives just above it, beside the oil pressure switch. |
I had to replace my Oil Pressure switch a while back, and found it much easier to just drop the starter and replace the switch from underneath. You may want to consider dropping the starter as well, being the knock sensor is in the same area as the Oil Pressure switch.
(the starter comes out pretty easy) |
Here's a picture of the location https://www.chevyhhr.net/forums/atta...-4-1578476.jpg

If there is a knock you would hear/feel it.
Why would you think 89 Octane would fix a fault in the knock sensor? Which is basically a microphone. |
I think the bolt is just loose.
