CS8CT-381 sensor

Autocar DEF Level Sensor (Part #JKA05713)

Part #JKA05713 is an Autocar Diesel Exhaust Fluid (DEF) level sensor used in the aftertreatment system of Autocar terminal tractors and yard trucks. This sensor is mounted in or near the DEF tank header assembly and monitors the fluid level inside the DEF tank, sending accurate readings to the truck’s ECM and dashboard display. It helps ensure proper SCR (Selective Catalytic Reduction) operation by warning the operator when DEF levels are low and preventing emissions related shutdowns.

Key Features

• Helps maintain proper SCR emissions system performance

• Sends DEF level data to ECM and dash warning systems

• Prevents low-DEF derate conditions and emissions faults
