Sensors - Edelbrock 3530 Owner's Manual

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
induction system and require no installation. The O
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.
