The new Delta P line routing that is used allows for water to drain away from the sensors which helps prevent the tube assemblies from clogging causing incorrect readings.
The tables below contain the part numbers that are needed for the different lines groups that are available. Ensure that the correct lines group is chosen for correct installation and operation. The Clean Emissions Module (CEM) part number must be used to identify the correct sensor group
Table 2 contains the effective serial numbers for this change.
