What does the T2 probe do?

What does the T2 probe do?

• A. Provides temp data to the FADEC to set engine parameters. The probe is electrically heated.
• B. Measures ambient air temperature only.
• C. Regulates hydraulic pressure to the engine.
• D. Sends oil pressure data to the EEC.

Answer: (A)

The T2 probe is the core inlet temperature sensor that feeds the FADEC with the engine’s core temperature, and the FADEC uses that temperature data to calculate fuel flow and other engine parameters for safe, efficient operation. It is electrically heated to prevent icing and to keep readings accurate and responsive in cold or humid conditions. This distinguishes it from ambient temperature sensors, hydraulic regulators, or oil-pressure data paths, which are unrelated to the T2 measurement.
