What It Helps Address

• Faulty exhaust temperature sensor readings
• Emission control warning lights related to EGT monitoring
• Incorrect sensor output affecting engine management strategy
• Replacement needs on high-mileage Nissan Armada, TITAN, TITAN XD, NV2500, and NV3500 models
• Service repairs where the original sensor has failed or drifted out of specification

Installation Notes

Confirm the vehicle year, model, and production cutoff before ordering, since several applications are limited by build date. Compare the original sensor connector and location to the existing unit, and verify the interchange reference 22630EZ30A when matching the part.

For best results, inspect the surrounding exhaust components for heat damage, corrosion, or wiring issues before installation. Use the vehicle service information for the correct removal and torque procedure.
