Thermal Manifold Absolute Pressure Sensor
WARNING: This page does not describe the selected car, but rather 32 other vehicles, including the 2002 Mercury Sable, 2002 Mercury Mountaineer, 2002 Mercury Grand Marquis, 2002 Mercury Cougar, and 2002 Lincoln Town Car. However, it is still accessible from the selected car via links, so may be relevant.
Thermal Manifold Absolute Pressure (TMAP) sensor consists of a Manifold Absolute Pressure (MAP) sensor and an integrated thermistor. Thermistor part of TMAP sensor is currently not being used. MAP part of TMAP sensor measures intake manifold air absolute pressure. PCM uses information from TMAP sensor, Throttle Position (TP) sensor, Mass Airflow (MAF) sensor, Engine Coolant Temperature (ECT) or Cylinder Head Temperature (CHT) sensor and Crankshaft Position (CKP) sensor to determine how much exhaust gas is introduced into intake manifold through EGR system.
