Large 15oz Diesel Tech Mug - Every Road Leads to the DEF Sensor

Every road leads to the DEF sensor. A big mug for the shop coffee pot. The wrap shows all eight highways curving in from the edges and meeting at the small sensor in its red destination ring, plus the code reader with the warning triangle and same-again arrow.

Fill it before the first truck rolls into the bay and refill it when the same warning comes back. It is a fun gift for diesel technicians, shop foremen and fleet managers.
