Neon L4-2.0L SOHC (1995)
Fuel Gauge Sender: Description and Operation
Fuel Level Unit No Change Over Miles
NAME OF CODE:
Fuel Level Unit No Change Over Miles
WHEN MONITORED:
Ignition ON.
SET CONDITION:
The fuel level sensor signal circuit voltage at Powertrain Control Module (PCM) cavity 13 does not change a calibrated amount over a calculated
number of miles.
THEORY OF OPERATION:
The voltage at the fuel level sending unit 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
