Walker Products 273-10306 OE Replacement Exhaust Gas Temperature EGT Sensor

The Walker Products 273-10306 is a direct-fit replacement Exhaust Gas Temperature (EGT) sensor — also known as an Exhaust Temperature Sensor (ETS) or Heat Temperature Sensor (HTS) — engineered to restore proper exhaust system monitoring to factory specifications. This sensor continuously measures exhaust gas temperatures and transmits real-time data to the engine control unit (ECU), enabling precise management of critical emission and engine functions.

The sensing element works by changing electrical resistance in response to temperature changes. The ECU reads this resistance and calculates the exhaust temperature, which it uses to regulate a range of engine processes including diesel particulate filter (DPF) regeneration, selective catalytic reduction (SCR), exhaust gas recirculation (EGR), turbocharger boost control, and overall combustion management.

Key Features:

• Meets or exceeds all OE specifications for form, fit, and function — 100% OEM-based sensor program
• Constructed with high-temperature metals and ceramics for stable, accurate output under extreme heat, vibration, and contamination
• Temperature measurement range up to 900°C — sensor accuracy of ±2.5°C from -40°C to 278°C and ±0.9% from 278°C to 900°C
• Industry-leading sensor response time: less than 11 seconds at 300°C (gas velocity of 11 m/s)
• Direct-fit plug-and-play connector — no universal wiring or modifications required
• 100% tested before leaving the factory for peak performance and reliable operation
• Manufactured by an ISO 9001/IATF16949 certified facility

Prompt replacement of a failed EGT sensor is important — a defective sensor can result in an obstructed particulate filter and potential engine damage. The Walker Products 273-10306 provides a quality, confidence-inspiring replacement backed by Walker's decades of engine management manufacturing expertise dating back to 1946.
