Why Replacement is Important:

A properly functioning temperature sensor ensures accurate readings of engine or exhaust temperatures. If the sensor fails, the ECU may receive incorrect data, potentially causing poor combustion timing, increased emissions, reduced fuel efficiency, or unnecessary DPF/SCR regeneration cycles. Faulty temperature readings can also risk engine overheating and damage to aftertreatment systems. Timely replacement maintains optimal engine performance, protects critical components, ensures compliance with emissions regulations, and prevents costly downtime. Regular inspection and replacement are essential for heavy‑duty diesel engines to operate reliably and efficiently over the long term.
