Why Replacement is Important:

A fully functioning pressure temperature sensor is crucial for engine performance. Malfunctioning sensors can cause inaccurate air-fuel mixture calculations, reduced combustion efficiency, poor fuel economy, increased emissions, rough idle, or loss of power. In heavy-duty engines, sensor failure may trigger diagnostic codes, limp mode, or unnecessary DPF/SCR regenerations. Timely replacement ensures the ECU receives precise data to maintain optimal engine performance, improve fuel efficiency, protect critical components, and comply with emissions standards. Regular inspection and replacement prevent costly downtime and extend the engine’s lifespan.
