Common Uses

• Restoring exhaust temperature sensor readings on diesel trucks
• Addressing DPF-related sensor faults on Silverado HD and Sierra HD models
• Replacing a failed OE base sensor in exhaust monitoring systems
• Correcting exhaust gas temperature signal issues that affect emissions diagnostics
• Servicing after-DPF or before-DPF sensor locations listed in the fitment data

Installation Notes

Verify the sensor location before installation, since fitment includes after-DPF, before-DPF, and DPF-related positions depending on year and model. Match the connector shape, terminal style, and thread diameter to the original sensor, and confirm the application against the vehicle’s emissions system layout before replacement.
