FUEL TEMPERATURE SENSOR VOLTAGE
PARAMETER
DEFINITIONThis parameter indicates the fuel temperature sensor voltage in volts.
NOTESSpecial notes:
Only perform these tests if the parameters do not correspond with the system
operation programming.
Conformity check with the engine stopped and the ignition on, or the engine running and the engine
coolant temperature > 80°C
