This module will help prevent a Service Engine Soon / Check Engine Light from illuminating and will prevent the ECM from displaying DTC codes related to an EGR modification. This requires a functioning EGR motor and position sensor to work. Installation will require stripping wire insulation and soldering, or the use of other mechanical fasteners like wire nuts or splice connectors. Soldering is the most reliable. If you are going to purchase this kit please feel comfortable with doing the installation.
