Sensor Failure 2. ECU Faulty 1. ECU Faulty 2. Engine will not start. Checkpoints: 1. Check Battery Voltage Trouble Shooting Steps: Sr. No. Steps Specifications Step 1 Check the Battery voltage Check the battery voltage Step 2 Check the ECU Physical check and replace the ECU Circuit Description: ECM senses the accurate air pressure value though Manifold Air Pressure sensor. The data is used to calculate air density and determine the engine's air mass flow rate, which in turn determines the required fuel metering for optimum combustion. Circuit Schematic Diagram:
