Why Replacement is Important:

A reliable pressure temperature sensor ensures the ECU receives accurate intake manifold data. Malfunctioning sensors can cause incorrect air-fuel mixture calculations, reduced combustion efficiency, poor fuel economy, higher emissions, rough idle, or power loss. In heavy-duty engines, this may trigger diagnostic codes, limp mode, or unnecessary DPF/SCR regenerations. Timely replacement maintains engine performance, improves fuel efficiency, ensures compliance with emissions regulations, and protects critical components from damage. Regular inspection and replacement help avoid costly downtime and preserve long-term reliability of the engine system.
