1.5L REVOTORQ ENGINE 189 SENSOR STANDALONE DIAGNOSIS Use multi-meter to check for signal voltage at pin1 and pin3. Supply Voltage: - 5V DC. Signal Voltage: 0.4 V at 10 kpa (absolute) 4.65 V at 115 kpa (absolute) Use TATA diagnostic tool to check for 'Intake manifold pressure and Air temperature' values. 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. 4. Check the resistance between the Sensor Temperature signal pin and EMS ECU, at Room temperature of 30 5. Degrees, it should be ~1080 Ohms. xvi. START STOP SWITCH Start Stop Switch also known as Push to Start Button. This is main component to trigger engine cranking and controls the completer vehicle power mode (OFF, ACC, IGN, & CRANK) for entire vehicle architecture. It is provided with multicolor LED to indicate different vehicle conditions to customer, OFF (No color) ACC ON (Amber) IGN ON (Green) CRANK ON (Green) Engine Run (Green) SWITCH LOCATION
