Drive with caution — fix soon.
This code means the fuel temperature sensor 'A' signal is dropping out intermittently rather than failing all the time. These faults are most often caused by a loose or corroded connector, a chafed or partially broken wire, or a sensor that's beginning to fail. Fixes usually involve finding and repairing the intermittent wiring or connector, or replacing the sensor.
$110 – $380
Varies by vehicle and root cause.
Usually yes, since the fault is intermittent and the engine often runs fine. But intermittent problems tend to get worse over time, so it's best to have it diagnosed within a week or two before it becomes a constant fault.
Repairs typically cost between $110 and $380. Tracking down an intermittent wiring fault can take extra diagnostic time, while a sensor replacement is a more predictable cost.
It's a moderate code. The intermittent nature usually means the engine still runs, but the inconsistency makes it worth fixing before the connection fully fails and causes more noticeable problems.
Because the fault only appears sometimes, a technician may not be able to reproduce it on demand. Diagnosing it often involves wiggle-testing connectors and wiring to find the loose or damaged spot causing the dropout.
