(Absolute pressure values ) Manifold pressure raw Manifold pressure read by the sensor FE1E Verification condition: 1. Do several power latches. 2. Check the delta between atmospheric pressure and manifold pressure. 3. Run the vehicle in city and highway condition. Component Details: The sensor serves to measure the absolute intake-manifold pressure as well as the temperature of the intake air stream of internal-combustion engines. The piezo-resistive pressure sensor element and a suitable circuitry for signal amplification and temperature compensation are integrated on a silicon chip. The measured pressure operates from above to the active side of the silicon diaphragm. The temperature sensor element is an NTCresistor. The sensor is installed after turbocharger at inlet manifold of the engine. Circuit Schematic Diagram: Component Location and Image:
