Full model list at the end of this description.

⚙️ Key Features

• Designed for SCR and aftertreatment monitoring
• High-temperature probe and sealed electrical connection
• Provides input to the engine and emissions control system
• Engine type: Turbocharged diesel with SCR exhaust aftertreatment

🔌 Function

Measures exhaust temperature and sends the value to the engine-control system for emissions management and component protection.

⚠️ Common Signs of Failure

• SCR or aftertreatment warning message
• Implausible exhaust-temperature reading
• Engine derate or reduced power
• Increased emissions or failed regeneration strategy
• Open-circuit, short-circuit or sensor-range diagnostic code

🛠️ Service Notes

• Check the replacement is the sensor specified for your engine and instrumentation — sensors sharing a thread can have quite different characteristics, and a mismatch gives plausible but wrong readings
• Let the engine cool and depressurise the system before removing a sensor from a coolant or oil passage, and be ready for the fluid that will come out
• Clean the threads and sealing face in the housing, fit a new sealing washer or O-ring where one is used, and do not pack the threads with sealant on a sensor that earths through its body
• Tighten to the figure in the workshop manual with a spanner on the hexagon only — these bodies crack easily and the thread in an alloy housing is easily stripped
• Reconnect the plug or terminal clean and secure, route the lead clear of hot and moving parts, then top up, bleed and run the engine and check the reading is sensible and steady while watching the joint for weeps
