E-ECU Sensors
The D12C has a total of eight sensors. Three of these have dual functions. This gives a total of 11
functions.
The dual function sensors are:
2 Turbo boost pressure/air temperature in inlet manifold.
5 Air temperature before intercooler and pressure drop indicator. Located in the union pipe between the
air filter housing and the turbocharger inlet.
8 Oil pressure/temperature.
The other sensors are:
1 Fuel pressure sensor. Senses the pressure after the fuel filter.
3 Camshaft position sensor. Located in the upper timing mechanism cover.
4 Engine coolant level. Located in the expansion tank.
6 Engine coolant temperature. Located in the rear end of the cylinder head.
7 Engine speed sensor. Located in the fly wheel cover.
Apart from the sensors above, the system includes a sensor for Atmospheric Pressure, located inside the
EECU.
