Revotron 1.2T 155 Circuit Schematic Diagram : Connector Information : Con ID Wire ID Color Size Material Option 1 940 BR/Y 0.75 FLRYB (AD) 2 63702005160 3 939 R/G 0.50 FLRYB (AD) 461 Y/GY 0.75 FLRYB (AD) Connector View : Component Specification : Boost Pressure Sensor is used to measure the pressure of the Intake Air at Intake Manifold (After Turbo). The piezoresistive pressure sensor element and a suitable circuitry for signal amplification are integrated on a silicon chip. The measured pressure operates from above to the active side of the silicon diaphragm. Sensor Stand alone Diagnosis : 1. Give 5V Power Supply to the Sensor Supply pin and Ground to the Sensor Ground Pin 2. Keep the sensor in a pressurized environment of 50 bar. 3. Measure the Voltage between the Sensor pressure Signal Pin and Ground, it should be 2.1 Volts approx. Diagnosis: Use multimeter to check for signal voltage at pin1 and pin3. Supply voltage :- 5V DC. Signal Voltage : 0.4 V @ 10 kpa (absolute) 4.65 V @ 115 kpa (absolute)
