Good afternoon,

I attached the procedure and pictures of the location for you.

Why are you replacing this? Do you have a code? If, what is the code?

Installation

NOTE: Do not apply thread sealant to the sensor threads. The sensor is coated at the factory and applying additional sealant will affect the sensor's ability to detect detonation.
