Intake Air Temperature Sensor

The air intake temperature sensor is built into the TMap sensor. Air temperature information is used in conjunction with intake manifold pressure information as supplied by the MAP enabling the EMS2000 to calculate the volume of air being consumed by the engine. The sensor is a NTC type, supplied 5 volts by the EMS2000.

• A high voltage reading indicates high sensor resistance, or low temperature.
• A Low voltage reading indicates low sensor resistance or high temperature.
