Coolant temperature sensor for the engine block outlet
Fuel temperature sensor for the low-pressure fuel
Intake manifold temperature sensor
Oil temperature sensor
Sensor for the turbocharger compressor inlet temperature
Temperature sensor at the water pump outlet for the SCAC
Temperature sensor for the high-pressure fuel systemThe sensor signal for the passive sensors is routed to terminal 1 of each sensor connector. The sensor return for the passive sensors is routed from the ECM terminal 2 of each sensor connector.
