Do you know the actual code number? If not, you can turn key on-off-on-off-on within 5 seconds and code should display on odometer.

This code is for knock sensor 2, almost always means the knock sensor has failed. Spark plugs shouldn't cause this code. Here are replacement instructions for sensor. Let me know if you have more questions. Thanks.-https://www.dropbox.com/s/y69dfs7xxua60im/knock1.pdf?dl=0-https://www.dropbox.com/s/62elxwktcprc25b/knock2.pdf?dl=0

How do you change it?
Expert:  Dan replied 8 months ago.
You need to remove the intake manifold as shown in 2nd link. It is a fairly big job, I'd consider paying a shop the 2 hours labor vs doing it yourself. Let me know if you have questions, thanks.
