Digital Hall Effect and Optical Sensor Types
The second type of sensor found of crank and camshafts known as a Hall Effect (this includes optical sensors) sensor. This style of sensor has a transistor and some electronics built into the sensor itself and will generally require a power supply ...
Reluctor Sensor Types
Variable Reluctance Transducers (VRT or simply reluctor) – this kind of sensor produces a sine wave output. Generally a VRT sensor will have only 2 wires (a third wire may be present but its generally a shield wire to help protect the signal from ...
Trigger Wiring (Crank and Cam Angle Sensors)
The most critical sensor on the engine is the engine speed sensor, without this sensor the ECU would not know that the engine is moving and therefore it would never fire a spark nor inject any fuel. The ECU gets information from the crankshaft and ...
Throttle Position Sensor input
The throttle position sensor is mounted to the throttle butterfly shaft to measure its rotation. A TPS is common on many late model engines and the Haltech sensor should attach with little or no modification. The throttle shaft must protrude from the ...
Manifold Absolute Pressure Sensor
The MAP sensor is used to convert the manifold pressure into an electrical signal for the ECU to use. The sensor works in absolute pressures, thus its calibration is not affected by changes in barometric pressure. The vacuum - and in the case of ...
Knock Sensor (Optional)
Knock sensors detect engine knock and sends a voltage signal to the ECU. The Elite Series ECU uses the knock sensor signal to modify ignition timing if knocking occurs. Knock Sensors can be connected to the knock input connections on the ECU.
Internal MAP Sensor
The MAP sensor is used to convert the manifold pressure into an electrical signal for the ECU to use. The internal Manifold Absolute Pressure Sensor is a 3Bar sensor which is rated up to 200kPa of boost (2Bar / 29psi). Connect the sensor to the inlet ...
Inlet Air Temperature Sensor
The air temperature sensor is used to compensate for changes in air density due to air temperature. Cold air has a higher density than warm air and therefore requires a greater volume of fuel to maintain the same air/fuel ratio. This effect is most ...
Exhaust Gas Oxygen Sensors (Optional)
The optional exhaust gas oxygen sensor must be mounted in the exhaust pipe near the exhaust header or extractors, usually after the collector. The sensor uses the exhaust gas to detect if the engine is running lean or rich. Many late model engines ...
Coolant Temp Sensor
The coolant temperature sensor has a solid brass temperature sensing tip. The coolant sensor supplied is an industry standard component and some engines may already have provision for this type of sensor. The coolant temperature sensor is designed to ...
