(MAP) Manifold Absolute Pressure Sensor

Manifold Absolute Pressure Sensor or MAP sensor provides instantaneous manifold pressure information to the engine’s electronic control module (ECM). This data is used to calculate air density and determine the engine’s air mass flow rate, which in turn d

ABOUT YOUR VEHICLES’ MAP Sensor

What does a MAP Sensor do?
The MAP sensor converts engine vacuum/manifold pressure to an electrical signal so the computer knows how much load the engine is under. This data is the basis for fuel delivery and timing control.

Where is the MAP sensor located?
The MAP sensor is typically located in the air cleaner, fender wall, firewall, intake manifold, or under the dash.

Will a malfunctioning MAP Sensor illuminate the check engine light or affect vehicle operation?
Yes, a failing sensor can illuminate the MIL and may cause the engine to have a rich or lean fuel mixture condition.

What are the common causes of failure?
Typically these sensors fail due to the constant contact of the movable wiper arm over the sensor element and the exposure to the high underhood heat.

How to determine if the MAP Sensor is malfunctioning?
The Diagnostic Monitor tests for voltages outside of the normal range. The PCM also compares actual MAP output to calculated values to determine sensor performance deterioration. The calculated values are based on TP and various engine load factors.
