Hello Everyone.  Hope the weather isn't too harsh up there, S Cal is soaking and cold. Has anyone seen a message "radiator outlet thermistor Low voltage"  (code p1117) It is driving me crazy.  

Thank you for the quick response Craig, this model does not have an outlet temperature thermistor as do the later 4.4 BMW engines!

Sorry for the confusion, this is a Range Rover.   95-99 vehicles had separate sensors for the gauge and the ECU. The 99-02 vehicles had a dual sensor, temp sensor (for the gauge) and a thermistor for the ECU. 2003 models with the 4.4 used an electronic thermostat.  This system had the manifold thermistor (monitoring rad inlet temp, and a lower radiator thermistor (monitoring rad outlet temp)  the resultant opened or closed the electronic thermostat.  it is quite difficult to keep up with the constant "changes"  from BMW and then Ford!

Thank you for the response, on any standard obd car the generic code P1117 indicates a faulty sensor or a "stuck open" thermostat, this car has an additional switch at the bottom hose but no wiring for it anywhere in the harness.
