Hello. My name is ***** ***** I will be assisting you today. The knock sensors are located under the intake manifold. In order to access them, the manifold will need to be removed. Here I am supplying the location information for the sensors, inspection information, removal information for the intake manifold. There is no stand-alone information for removing the intake manifold and it is located inside the cylinder head removal process. This combined information should have you set.

If you require more information on this issue and/or are not satisfied, let me know, please, and I will attempt to assist you further on this. I hope this information points you in the right direction. If you have any further questions or concerns on this issue, feel free to ask. If you are satisfied, and have found this information helpful, a positive rating would be greatly appreciated. Thank you.

A positive rating does not close the session. We will still be able to communicate and I will continue to assist you with this issue as needed.
