P0365 / p0366
New to the forums! 09 Astra XR
I got this code and I know itís the camshaft position sensor. I know it could either be dirty or damaged. My valve cover is leaking so maybe some oil got around in the sensor or itís actually time to change it.
I couldnít find any diagrams or pictures of the location of the sensor.
I know itís on the drivers side but thatís all.
Anyone got any pictures or diagrams of where to find it?

Re: P0365 / p0366
Did you buy that NH Opel?
Weeping valve cover gasket is a popular Astra problem due to failed PCV membrane on the Astra, which is part of the valve cover. As that may blow out the new valve cover gasket again quickly, you might address it.
- You could try cleaning the PCV membrane which might be stuck shut but at this point the rubber often rips. bmw-vanos sells the rubber membrane for about $27 shipped; but the plastic valve cover clips holding it in are delicate after years of heat. You can buy a new valve cover housing which has the PCV valve built into it. There are plenty of posts here with more info about other telltale signals of failed membrane and repair.
There are a few popular camshaft issues with the z18xer engine. They show a variety of codes and you will see p0365 is not so popular.
A few things to start with based on popular Astra failures:
1. Remove the orange oil filters from the camshaft position actuator solenoid valves (There is a technical service bulletin from GM and several posts here including)
This guy cleans his solenoid valves not sure if he added a bit of oil before reinstalling but I don't remember people here doing this.
Be very careful removing the wiring harness and the delicate actuator plastics as a few guys here have broken them.
p0365 code is typically for the exhaust actuator but can't be 100% sure; you can try cleaning and swapping.
2. Changing the oil can help
3. If the car has a "diesel sound" for a few seconds at start up or periodically or always, then that is an indication that camshaft gear adjusters are having issues. This is another popular Astra problem but requires removing timing belt and is a somewhat painful repair. If you do this replace the timing belt (and the related tensioner & idler pulley in the kit as the idler pullies tend to spit out grease). I think people typically do the change if there are codes, diesel noise is sustained for more than a few seconds, there is drivability issues, etc. There are lots of posts here.
Finally the engine is the z18xer. In the US, several recent Chevy models have very similar z18xer engines (Cruze, Aveo) and in Europe (Astra, Zafria, Vectra). That helps with search (the z18xe engine differs for these issues).

Re: P0365 / p0366
Thank you for the reply! I bought a Saturn Astra XR 1.8L (I live in Canada)
I will replace the valve cover gasket and clean the PCV valve as well. There is a lot of oil around the valve cover so I'm sure that should definitely help.
In regards to, P0365, I was reading that it is related to the Camshaft Position Sensor, and not the solenoid, and that sludged oil can get into the sensor and damage it (leaky valve cover = oil everywhere).
Where can I find the Camshaft Position Sensor? I'd like to inspect it and give it a clean just for the sake of mind.
Also, I will clean the Camshaft Position Solenoid as per the Youtube videos just to tick that off the list.
Thank you for pointing out the engine as that will surely help with search engines. I didn't know that Cruze & Aveo have same engine.
