P0182 — Fuel Temperature Sensor A Circuit Range/Performance
Drive with caution — fix soon.
What P0182 means
This code means the fuel temperature sensor 'A' is sending a reading that falls outside the normal range or doesn't match what the computer expects under current conditions. It often points to a drifting or failing sensor, but can also come from wiring problems or a poor connection. Common fixes include replacing the sensor or repairing its wiring and connector.
Common symptoms
- Check engine light is on
- Slightly reduced fuel economy
- Occasional rough idle
- Minor hesitation under acceleration
- Possible hard starting in very hot or cold weather
Common causes
- Drifting or failing fuel temperature sensor
- High resistance in the sensor wiring
- Corroded or loose sensor connector
- Contaminated or degraded fuel affecting readings
- Faulty engine control module (rare)
Typical repair cost
$110 – $350
Varies by vehicle and root cause.
Frequently asked questions
Can I keep driving with a P0182 code?
Usually yes, especially if the engine runs normally. The sensor reading is just out of range, so it's not an emergency, but getting it diagnosed within a week or two helps avoid creeping fuel economy or emissions problems.
How much does it cost to fix a P0182 code?
Repairs typically cost between $110 and $350. Cleaning a connector or fixing wiring is cheaper, while replacing the fuel temperature sensor is the larger expense.
Is a P0182 code serious?
It's a moderate code. It rarely causes serious drivability issues on its own, but an inaccurate fuel temperature reading can hurt efficiency and emissions, so it's worth fixing.
What's the difference between range/performance and a circuit fault?
A range/performance code means the sensor is working but reporting a value that doesn't make sense, while a circuit fault usually means an electrical problem like an open or short. P0182 points to a plausible-but-wrong reading, often from a drifting sensor.
