Rated Fuel Limit - This term indicates the maximum allowable fuel position (longest injection pulse). This position will produce rated power for this engine configuration.Reference Voltage - Reference voltage is a regulated voltage and a steady voltage that is supplied by the ECM to a sensor. The reference voltage is used by the sensor to generate a signal voltage.Sensor - A sensor is a device that is used to detect a change in pressure, temperature, or mechanical movement. The information that is detected is converted into an electrical signal.Short Circuit - A short circuit is a condition that has an electrical circuit that is inadvertently connected to an undesirable point. An example of a short circuit is a wire which rubs against a vehicle frame and this rubbing eventually wears off the wire insulation. Electrical contact with the frame is made and a short circuit results.Signal - The signal is a voltage or a waveform that is used to transmit information typically from a sensor to the ECM.Starting Aid Switch - The starting aid switch is used for injection of ether in cold weather.Supply Voltage - The supply voltage is a constant voltage that is supplied to a component in order to provide electrical power that is required for the component to operate. The power may be generated by the ECM or the power may be battery voltage that is supplied by the vehicle wiring.System Configuration Parameters - System configuration parameters are parameters that affect emissions and/or operating characteristics of the engine.Throttle Backup Switch - This switch is used to adjust the engine speed when there is a problem with the throttle signal.Throttle Position - The throttle position is the interpretation by the ECM of the signal from the throttle position sensor or the throttle switch.Throttle Position Sensor - The throttle position sensor is an electronic sensor that is connected to an accelerator pedal or a hand lever. This sensor sends a PWM signal to the ECM that is used to calculate desired engine speed.Throttle Switch - The throttle switch sends a signal to the ECM that is used to calculate desired engine speed.Timing Calibration (TC) - Timing calibration is the adjustment of an electrical signal as a means of correcting the timing error between the crankshaft and the engine speed/timing sensor.Timing Calibration Probe - The Timing Calibration probe is a magnetic transducer that is used to sense the crankshaft position for the purpose of calibrating the engine speed/timing sensor.Top Center - Top center refers to the crankshaft position when the engine piston position is at the highest point of travel. The engine must be turned in the normal direction of rotation in order to reach this point.Total Tattletale - The total tattletale is the total number of changes to all the parameters that are stored in the ECM.Turbocharger Inlet Pressure Sensor - This analog sensor measures the pressure of the inlet air to the turbocharger compressor.Turbocharger Outlet Pressure Sensor - This analog sensor measures the pressure
