The Manifold Pressure Sensor (also known as the Manifold Absolute Pressure Sensor or the Manifold Differential Sensor) is a device that is used to calibrate the fuel delivery on most modern ECU Controlled (computerized) engines.
Used predominantly after the institution of the OBD-II (On-Board Diagnostics), it is used to calculate the difference between manifold pressure (measured in inches of Mercury) and ambient or atmospheric pressure. The computer uses this sensor to determine, based on the differential between the two, the conditions present requiring the fuel delivery to be adjusted.
At higher altitudes, the ambient pressure is lower, reducing the value when comparing the two readings. At lower altitudes, the atmospheric pressure is higher, generating a larger number. The larger the number, the less fuel is delivered, as decreased atmospheric pressure indicates (under normal conditions) a decrease in the density of the air and thereby a decrease in available oxygen, the second component required for efficient combustion.
Additionally, when the throttle plate is opened, the value generated by the Manifold Pressure Sensor (usually called the MAP) is reduced as the pressures equalize. This tells the computer that the operator is attempting to accelerate, adjusting timing, injector pulse width and other sub-systems to assure proper and efficient response.

It's the MAP sensor...Manifold Absolute Pressure.

Manifold Absolute Pressure Sensor ( MAP )
The MAP sensor is located on intake manifold.
The 2003 Mondeo does not have a IAT Sensor is has a Temperature and Manifold Absolute Pressure Sensor (TMAP) The TMAP sensor fits directly into the inlet manifold and accurately measures the vacuum from the engine. The TMAP sensor consists of a temperature sensor and a pressure transducer and therefore replaces the IAT and the MAP sensors. The TMAP sensor provides the powertrain control module with information relating to inlet manifold vacuum and barometric pressure along with the temperature of the air in the inlet manifold. With the ignition on but without the engine running the sensor reads barometric pressure and when the engine is running, the sensor reads inlet manifold vacuum.
A 1998 Jeep Cherokee does not have a mass airflow sensor. It uses a manifold pressure sensor, MAP, which is on the rear of the intake manifold.
Manifold Absolute pressure measures the change in manifold pressures. It is an input or data gathering sensor that the computer uses for management.

No map sensor is manifold absolute pressure sensor and tps throttle position sensor
The Manifold ?æAbsolute Pressure sensor is located on top of the manifold. It is just forward of the intake manifold and held in place with a bracket assembly.
This is the Manifold Absolute Pressure sensor. It is located on the top of the motor between the fire wall and the intake manifold case.
The oil pressure sensor is on the oil cooler, under the intake manifold.
The oil pressure sensor is under the intake manifold on a 3.6L.
It does not have a MAF, it uses a manifold absolute pressure (map) sensor. Which is bolted to the front of the throttle body.It does not have a MAF, it uses a manifold absolute pressure (map) sensor. Which is bolted to the front of the throttle body.
Manifold Absolute Pressure/Barometric Pressure Sensor
The MAP (manifold absolute pressure) sensor monitors the intake manifold pressure changes and adjusts the fuel delivery based on its reading
It does not use a MAF. It has a MAP sensor (manifold absolute pressure) on the front of the intake manifold.
The manifold absolute pressure (MAPO) sensor monitors the air pressure as an important input to the vehicle's EFI system. On this application the MAP is bolted to the intake manifold, from where it gets its pressure readings.
It does not have a MAF, it uses a MAP (manifold absolute pressure) sensor.
In that context, "MAP" stands for "Manifold Air Pressure". The sensor is detecting the pressure of the intake air and it's usually on the air cleaner, the manifold or the throttle body.
