8. MANIFOLD ABSOLUTE PRESSURE SENSOR (MAP)
The Manifold Absolute Pressure Sensor (MAP) is located on top of the throttle Body.
SPECIFICATION
Operating Temperature: -20°C to +80°C
Supply Voltage: 5 V
The MAP sensor monitors the manifold pressure at the intake end and provides data to the ECU on a real time basis.
This helps the ECU to calculate the air density and the air inflow rate anddetermines the fuel injector opening duration
to provide the required amount of vaporized fuel into the combustion chamber for optimum performance of the
motorcycle.
9. AMBIENT AIR (TA) SENSOR
The TA sensor is located on the rear side of the filter box assembly in Bullet EFI / Classic EFI models and on the outlet
pipe of the air filter housing in Continental GT models.
The ambient temperature input is provided to the ECU on a real time basis, based on which the ECU determines the
fuel injector operating time to provide the required amount of vaporized fuel into the combustion chamber for
optimum performance of the motorcycle.
SPECIFICATION
Operating Temperature: -30°C to +120°C
Supply Voltage: 5 V+0.5 V
