P0325 Nissan -my 02 Nissan Altima 6 cylinder knocks

Question

My 2002 Nissan 6-cylinder Altima knocks when I use mid-grade fuel. Is there a way to adjust it to use low-grade?

Thanks!

Answer 1

P0325 Knock sensor 1 circuit malfunction (Bank 1 or single sensor)

You can use low grade, You just have a knock sensot that just does not work properly anymore

 The knock sensor on the left is worn knock sensor , this is common when it comes to age and use
