Data Parameters Engine Parameters
EXHAUST GAS TEMPERATURE
EXHAUST TEMPERATURE (TWC MODEL)
Range: ______________________________________________________ not available
Used on HFM, LH, ME10, ME27 and ME28 systems. These parameters are the ECU calculated
exhaust gas temperature based on multiple input signals, and shows exhaust gas temperature.
The measurement units can be changed from degrees Celsius (°C) to degrees Fahrenheit (°F).
EXHAUST TEMPERATURE LEFT
EXHAUST TEMPERATURE RIGHT
Range: ______________________________________________________ not available
Used on ME10 systems. These parameters are ECU-calculated exhaust gas temperatures for
the left and right cylinder banks based on multiple input signals, and shows exhaust temperature.
The measurement units can be changed from degrees Celsius (°C) to degrees Fahrenheit (°F).
The preset measurement is °C.
FAN CAPACITY REQUEST BY A/C
FAN CAPACITY REQUEST BY ENGINE
FAN CAPACITY, EFFECTIVE
Range: _________________________________________________________ 0 to 100%
Used on ME27, ME28, and SIM4 systems. These parameters indicate the amount of the fan
capacity used, as requested by the A/C system or the engine.
FRONT AXLE SPEED
Range: ___________________________________________________ 0 to vehicle max
Used on ME27 and ME28 systems. This parameter indicates the speed of the front axle based
on input signals to the ECU from the wheel speed sensors. The measurement units can be
changed from KPH to MPH.
FUEL CANISTER PRESSURE DIFF.
Range: ____________________________________________ –50 to 30 HPA or 0 to 5 V
Used on ME27, ME28 and SIM4 systems. This parameter indicates fuel canister pressure
difference. This pressure sensor is integral to the fuel level sender assembly. It detects pressure
in the fuel evaporative system. Pressure varies with the pulsed actuation of the purge control
valve. At sea level with the gas cap removed, normal voltage should be about 2.9 to 3.0 volts.
FUEL LEVEL
Range: _______________________________________________ 0 to full tank capacity
Used on SIM4 systems. This parameter displays the fuel level in liters.
FUEL PUMP
Range: __________________________________________________________ ON/OFF
Used on LH systems. This parameter indicates the state of the fuel pump. The display reads ON
when the fuel pump is energized and OFF when the pump is not running.
FUEL RACK TRAVEL
Range: __________________________________________________________ variable
Used on ERE/EVE/ASF (IFI Diesel)) diesel systems. The amount of travel is measured in
millimeters. With the engine warm at idle, the normal travel range is 7.5 to 9.5 mm. Cold engine
travel range is from 12 to 18 mm. With the engine fully warm, under load, fuel rack travel should
read more than 12 mm. The fuel rack integral to the main fuel injection pump controls the fuel
volume to the injectors, and works in conjunction with the fuel quantity actuator. The fuel rack
position sensor measures the amount of travel of the fuel quantity actuator control rod.
