Why Replacement is Important:

Replacing a faulty DPF temperature sensor is critical for proper aftertreatment performance and emission compliance. Incorrect temperature readings can disrupt DPF regeneration, leading to soot accumulation, increased exhaust backpressure, reduced engine efficiency, and potential derate conditions. Prolonged sensor failure may cause excessive thermal stress or damage to the DPF and related components. Timely replacement restores accurate exhaust temperature monitoring, ensures effective regeneration cycles, maintains optimal fuel efficiency, and protects the exhaust aftertreatment system, helping extend service life in heavy-duty and industrial diesel applications.
