Fuel Level Unit No Change Over Miles
NAME OF CODEFuel Level Unit No Change Over Miles
WHEN MONITORED
Ignition on
SET CONDITION
The low fuel sense circuit voltage at the PCM does not change a calibrated amount over a calculated number of miles.
THEORY OF OPERATION
The voltage at the low fuel sense circuit sends a variable voltage to the powertrain control module to indicate fuel level. The purpose of this feature is to prevent false setting of misfire and fuel systems monitor codes when the vehicle is operating at low fuel levels.
POSSIBLE CAUSES
- Open sensor signal circuit
- Fuel level sending unit failure
