What to tell the garage about P0095

Do not drive. Intake air temperature sensor 2 has a circuit fault, so the computer may not trust the second air-temp reading it uses when mixing fuel.

Take these reviewed, code-specific details with you. They help the garage confirm the fault without turning this page into a repair procedure.

What does P0095 mean?

P0095 is a generic (SAE standard) powertrain code reported by your car’s engine control unit. It sits in the P00xx block, which covers fuel and air metering. The stored description is “Intake Air Temperature Sensor 2 Circuit”. The code itself tells you which circuit or system tripped the fault — not always the exact part that failed.

Will P0095 fail an MOT?

An illuminated engine management light is a Major defect at MOT until repaired and the lamp stays off. P0095 is an intake-air temperature circuit flag, not a named MOT emissions reading.
