I replaced the knock sensors with ACDELCO parts. The check engine light came back on a few days later with the same code.
Do you
have the same problem?

Hi,

The code is specific to bank 2. See pic 1 below. Did you replace the one on the passenger side of the engine compartment or were both replaced?

Next, when you tighten the new sensor, it is important that it is to specification. It should be tightened to 18 ft/lbs. Is that what was done?

Let me know.

I changed both. And can't recall if I torqued it or not. Probably not. This was over 2 months ago.

Hi,

If by any chance they came loose, it will cause issues. Do me a favor. Take a look through the description and the diagnostics below. Let me know if you feel comfortable performing them. Also, if you need any other info on how to do it, let me know.

Let me know.

Hi,

I'm not sure what you mean by Hz. Hz stands for hertz. It is a unit of frequency used to measure sound waves.

The torque specs for the sensors is 18 ft/lbs. Let me know.

Take care and feel free to let me know if I can help.

Take care,

Joe
