Knock sensor. Please help!

Asked by Jun 22, 2017 at 02:29 PM about the 2010 Chevrolet Cobalt

Question type: Maintenance & Repair

hey guys was wondering if you can help me out, I have a
2010 cobalt LT and the check engine light came on
recently so I pulled the codes and p0327 came up and
said it might be the knock sensor, a knock in my engine or
low fuel pressure. I dont really hear a rattle coming from
the engine and after I pulled the codes the check engine
light turned off. Maybe it's a bad connection with the
sensor?? Any help is appreciated and thanks in advanced
guys

Maybe. A bad connection could show up as a failed sensor. Check the connection and drive it for a bit. Then scan for codes again. If it shows a failed sensor again, you might want to change the sensor. If it says low fuel pressure you might want to check your fuel pressure and correct it if it's low.
