It should be on the side of the middle of the block, held in place with a single bolt.
I could be wrong but I believe the sensor is circular

Knock sensor is located in the engine compartment, at the center rear of the engine below the intake manifold.

Thicker oil will not cure this. Try the oil recomended when new which is 5w 30 and an AC Delco oil filter. There is a difference in filters and can create this issue is inferior filters are used. Certain manufacturers actually have Technical Service Bullentins regarding this. It needs thinner when starting. Thicker oil will only remain thin when warm. If carbon is an issue then a good chemical flush and 2 oil changes may help. SeaFoam is highly recomended and productive. Knock, cam and crank sensors will not cause these issues. How does it run otherwise? Here are the values though;

Knock sensor
Testing


  1. Connect a digital multimeter to the KS signal circuit and to the KS low reference circuit at the KS.
  2. Set the multimeter to the 400 mv AC hertz scale and wait for the display to stabilize at 0 Hz.
  3. Tap on the engine block with a non-metallic object near the KS while observing the signal indicated on the multimeter.
    NOTE Do not tap on plastic engine components.
  4. The multimeter should display a fluctuating frequency while tapping on the engine block. If not, replace the sensor.

Just common hand tools, this would include a metric wrench set and a 3/8" drive complete metric socket set. Air tools would be nice as well to speed the job up.

My 2006 chevy hhr gave me a p0327


Code 327 is a problem with the knock sensor circuit.
Code 304 is for a cylinder miss on number 4.
The knock sensor circuit would need to be tested, and you would need to figure out what is missing on cylinder 4. Spark, fuel, or compression.
