P0182 fault code: Fuel Temperature Sensor A Circuit Low

P0182 means “Fuel Temperature Sensor A Circuit Low” — a fuel and air metering fault in the powertrain.

Can I DIY?

Professional-only boundary. Garage only: a low A-circuit fuel-temperature voltage is not a home test.

What to tell the garage about P0182

Do not drive. Fuel temperature sensor A is stuck at a low electrical reading. The computer may treat the fuel as colder than it is, which can skew density compensation on the A input only.

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 P0182 mean?

P0182 is a generic (SAE standard) powertrain code reported by your car’s engine control unit. It sits in the P01xx block, which covers fuel and air metering. The stored description is “Fuel Temperature Sensor A Circuit Low”. The code itself tells you which circuit or system tripped the fault — not always the exact part that failed.

Will P0182 fail an MOT?

An illuminated engine management light is a Major defect at MOT (automatic fail) until the fault is repaired and the light stays off.

Is it safe to drive with P0182?

Do not drive. P0182 has no verified driving guidance. Do not drive until a garage traces the low A-circuit. A low reading is not proof the fuel is actually cold, and it is not sensor B.

Will P0182 fail my MOT?

An illuminated engine management light is a Major defect at MOT (automatic fail) until the fault is repaired and the light stays off.
