XUD11BTE on 406 sensors

Post by briansib »

Hi,

someone please tell me what the two sensors in front of the diesel fuel filter housing are for, one seems blue and the other brown. Im redoing my loom and i cant find connectors that go onto them so i think its better i know what they are.

Regards.

If on the water outlet (thermostat housing) they are
Blue: sensor for temperature gauge
Brown: sensor for cooling fan control.

A Green one (used on earlier engines) fed coolant temp info to the Injection ECU.
