General Specifications

Purpose & Function

• Measure exhaust temperature
• Monitor DPF regeneration temperature
• Protect the turbo, DPF, and exhaust system from excessive heat
• Help the engine computer control emissions systems
• Detect abnormal temperatures and trigger warning/fault codes

Signs of a Pressure Sensing Tube

• Check Engine light or aftertreatment warning
• DPF regeneration problems — regeneration may not start, may stop, or happen too frequently
• Fault codes related to exhaust temperature or the EGT sensor
• Reduced engine power / derate
• Poor fuel economy
• Unrealistic temperature readings — for example, the computer sees extremely high or extremely low exhaust temperature
• Increased emissions or problems with the DPF system
