Description Manifold Absolute Pressure Sensor (MAPS) is a speed-density type sensor and is installed on the surge tank. It senses absolute pressure of the surge tank and transfers the analog signal proportional to the pressure to the ECM.
Circuit Diagram
Inspection 1. Ignition "OFF". 2. Disconnect evaporator temperature sensor. 3. Using the multi-tester, Measure resistance between terminal "1" and "2" of evaporator temperature sensor. Specification Evaporator coretemperature [°C(°F)]Resistance[KΩ]Voltage[V]-20(-4)70.
Replacement 1. Disconnect the negative (-) battery terminal. 2. Recover the refrigerant with a recovery/ recycling/ charging station. 3. When the engine is cool, drain the engine coolant from the radiator. 4. Remove the expansion valve cover (A).
