Compatibility / Fitment:

Fits Kenworth and Peterbilt trucks with Paccar and Cummins engines and a 21 or 31 gallon DEF tank, using the Paccar -003 through -007 series DEF quality sensor.

Hard fitment gate — Paccar part number suffix:

Paccar built this sensor in more than one revision. This kit replaces the -003, -004, -006 and -007 series — Q21-6170-003, Q21-6127-006, Q21-6170-004, Q21-6167-004, Q21-6127-007 and their variants. The earlier -001 series uses a different DuraWRX sensor.

Read the part number off the sensor you are removing and match the suffix before ordering.

Installation: snap the harness's Deutsch DT06-4S connector into the sensor's DT04-4P, then connect the AMP end to the vehicle harness.

What is not included: the AMP 1-1418390-1 mating connector is not supplied.

Common interchanges: Q21-6170-003, Q21-6127-006, Q21-6170-003K1T, Q21-6127-003, Q21-6095, Q21-6092, Q21-6170-004, Q21-6167-004, Q21-6127-007

Conclusion:

DuraWRX ASP62DS21-FG is the bayonet-mount DEF quality sensor kit for Kenworth and Peterbilt trucks with 21 or 31 gallon DEF tanks, replacing the Paccar -003 through -007 series under twelve part numbers. Match your Paccar suffix before ordering — the -001 series uses a different sensor.
