Description and Purpose

Cat® Diesel Exhaust Fluid Sensor Head Unit(Part Number: 82196512) is an essential emissions control component designed to monitor and regulate DEF levels, temperature, and quality in diesel engines. This high-precision sensor ensures compliance with emission standards by providing accurate readings to the vehicle’s aftertreatment system. Engineered for compatibility with a wide range of Cat machines and the C4.4 engine, this sensor head assembly helps maintain optimal performance and efficiency.

Why Replacement is Important

A malfunctioning DEF sensor can lead to inaccurate fluid level readings, triggering warning lights and potentially reducing engine power due to emissions system faults. Replacing the sensor assembly ensures the proper functioning of the selective catalytic reduction (SCR) system, preventing costly downtime and maintaining compliance with environmental regulations.

Impact on Vehicle Performance

This DEF sensor head assembly integrates level, temperature, and concentration sensors for precise fluid monitoring. Equipped with an engine coolant-powered heater and a serviceable suction filter, it enhances cold-weather performance and extends the system’s lifespan. With a durable design and a harness length of 14.4 inches, this RoHS-compliant sensor is built to withstand demanding operating conditions, ensuring reliable emissions control and efficient engine operation.
