508 GT - P0656

Post by scotcruz »

Hi folks,

I have an intermittent P0656 Fault-fuel level showing up under ECU faults.

I have previously replaced the fuel filter so not sure why this has come back. Upon checking the Fuel Circuit Information, the only thing abnormal was the Voltage of Fuel Temperature Sensor showing as Value Invalid.

Could this be causing this? Please can someone advise this and also the location of the sensor?

Many thanks

I reckon it must have been fairly rare to get no responses. Thanks for telling us you've fixed it. Perhaps you could briefly tell us what you did?
