Electronic Control Unit (Ecu)

The ECU is located below the glove box near the fuse panel. It receives information from the various engine sensors to determine engine operating conditions at any particular moment. The ECU responds to these signals by sending a control signal to the fuel injector to determine the amount of time that the injector will be left open (injector "on" time). See Fig 1 .
