The powertrain control module has detected that the fuel temperature sensor is reporting a temperature higher than expected. This can occur if the sensor, its wiring, or the PCM's input circuit is faulty.
The sensor can fail and send a signal that is too high, triggering the code.
Chafed, broken, or corroded wiring or a loose connector can cause an incorrect high voltage signal.
An inadequate ground or voltage supply can raise the sensor signal above normal.
A problem inside the PCM's fuel temperature sensor input circuit can misinterpret the sensor signal.
No, in most cases the issue is a faulty sensor or wiring, not the computer.
No, the code relates to temperature sensor signal, not fuel pressure.
It may run, but the code can affect drivability and fuel efficiency, so it should be fixed.
It should be addressed promptly to prevent possible engine performance issues.
