Drive with caution — fix soon.
This code means the computer has detected a general malfunction in the fuel temperature sensor 'A' circuit, which monitors the temperature of the fuel to help calibrate the mixture. The problem is usually a failed sensor, damaged wiring, or a poor connector. Typical fixes include repairing the wiring or connector, or replacing the fuel temperature sensor.
$110 – $350
Varies by vehicle and root cause.
Yes, in most cases you can drive normally since this fault rarely affects day-to-day performance. Still, it's a good idea to have it diagnosed within a couple of weeks so a minor issue doesn't get worse over time.
Most repairs fall between $110 and $350. A wiring or connector repair is cheaper, while replacing the fuel temperature sensor adds parts and labor depending on the vehicle.
It's generally a moderate-severity code. It won't leave you stranded, but the sensor helps the engine run efficiently, so fixing it keeps your fuel economy and emissions in check.
It measures the temperature of the fuel so the engine computer can fine-tune how much fuel to deliver. Colder fuel is denser, so the sensor helps keep the air-fuel mixture accurate across different conditions.
