WUQ 273-10441 Exhaust Temperature Sensor

SKU CH-71AW-ZZ5ZH

Measures exhaust temperatures up to 900 °C to protect turbochargers, catalytic converters and particulate filters in diesel and gasoline engines

  • ProtocolBluetooth
  • Monitors turbo, catalyst, filter and NOx system temps
  • Protects diesel and gasoline engine components from overheating
  • Verifies exhaust system is functioning correctly
  • Measures up to 900 °C for accurate engine control
  • OE-grade metals and ceramics withstand heat and vibration

Vehicle Exhaust Monitoring

The Walker Products 273-10441 sensor measures exhaust gas temperatures up to 900 degrees Celsius. It monitors critical components including turbochargers, catalytic converters and particulate filters. The device supports both diesel and gasoline engine applications. Bluetooth protocol enables wireless data transmission for system diagnostics.

Sustained High-Temperature Operation

The sensor utilizes OE-grade high-temperature metals and ceramics for stable output. It maintains accuracy despite continuous exposure to extreme heat, vibration and contamination. The sensing element changes resistance reliably across the full operating range. This construction supports consistent particulate filter regeneration and selective catalytic reduction cycles.

Replaces Failed OE Sensors

This unit replaces a defective original equipment exhaust gas temperature sensor. The upgrade is worth it when the original sensor fails and triggers warning lights or regeneration faults. It restores proper engine computer control over turbo boost and exhaust gas recirculation. Buyers needing a different temperature range or thread specification cannot use this part.

Questions about this item

Does the 900 °C exhaust sensor heat up the cabin or add electrical load during long drives?

The sensor is passive and only reports temperature; it draws negligible power and adds no heat to the cabin.

What vehicle interface does the 273-10441 sensor need to communicate with the ECU?

It connects directly to the engine computer through the standard exhaust-gas-temperature sensor harness used by the vehicle.

Can the 273-10441 replace the original sensor on an older diesel particulate filter system?

Yes, it meets OE specifications for particulate-filter regeneration, SCR, EGR and turbo-boost monitoring on both diesel and gasoline engines.
