SENSORS
The Edelbrock Pro-Flo system interprets overall engine operating conditions and fuel/spark requirements based on readings from
sensors that measure specific engine conditions.
The Pro-Flo system includes five sensors:
1) Manifold Absolute Pressure
2) Manifold Air Temperature
3) Coolant Temperature
4) Throttle Position
5) Exhaust Oxygen (O
2
)
These sensors, with the exception of the O
2
and MAT (Manifold Air Temperature) sensors are designed as an integral part of the
induction system and require no installation. The O
2
sensor must be installed on the exhaust pipe near the engine with a welded
fitting, and the MAT sensor must be installed into the air cleaner base.
MANIFOLD ABSOLUTE PRESSURE SENSOR
The Manifold Absolute Pressure sensor, mounted on the air valve with a
bracket, converts air pressure (load) in the manifold, to an analog signal sent
to the ECU. For more information on Manifold Absolute Pressure, refer to the
section on Speed Density Electronic Engine Management. This sensor is
connected to the Main System Harness.
MANIFOLD AIR TEMPERATURE SENSOR
The Manifold Air Temperature sensor, is a
t h e r m i s t o r d e v i c e w h i c h m e a s u r e s a i r
temperature. This sensor must be installed
into the air cleaner base. Punch a 3/4” hole
in air cleaner base, debur any sharp edges,
