The repair for NOX Sensor #2 is identical to the replacement instructions for the Particulate Matter Sensor with the following amendments:
1. NOX2 is the forward of the two sensor bodies.
2. The sensor module for NOX2 is to the rear of the Fuel Filter (as opposed to the module for the Particulate Matter Sensor, which is forward of the Fuel Filter).
3. The original part number for NOX2 is 12641557. It has been replaced by an updated part - number 12662659.
