PRESSURE SENSORS

BAP SENSOR

The Barometric Air Pressure sensor
intake duct after the air filter, measures ambient air
pressure. The sensor reading is used to detect changes
in elevation and for turbo speed limiting for altitude.

BOOST PRESSURE SENSOR

The Boost Pressure Sensor
that is used for boost target control and for turbo speed
limiting. The temperature sensor will provide a fallback in
case the intake manifold temperature sensor (TMAP)
fails.
The TMAP sensor and the Boost Pressure Sensor may
be interchanged for testing purposes as the sensors are
the same.

FUEL PRESSURE SENSOR (EVAP
MODELS)
On EVAP models, the fuel pressure sensor
fuel pressure in the fuel supply line and sends pressure
data to the ECU. The ECU interprets the fuel pressure
data and raises or lowers fuel pressure based manifold
pressure.
The ECU also uses the fuel pressure sensor to prevent a
rich condition during a purge event.

TMAP SENSOR

The Temperature and Manifold Absolute Pressure
e
sensor (T-MAP) is located on the intake manifold after
the throttle body. The sensor is the primary control
sensor for the EFI system and it measures the pressure
of the air going into each cylinder.
The TMAP sensor and the Boost Pressure Sensor may
be interchanged for testing purposes as the sensors are
the same.
