Why is the coolant temp on my ECT sensor low?
Why is the coolant temp on my ECT sensor low?
This DTC tells you that the PCM is seeing a coolant temperature of -46° F (-50° C). In technical terms, the PCM is seeing a very high voltage drop across the ECT sensor’s circuit, which it translates into an extremely low temperature. Coolant temp sensor’s wires have an ‘open-circuit’ problem (usually due to a cut wire).
What does the coolant temperature sensor on a Ford do?
In a nutshell, the coolant temperature sensor on your Ford vehicle is a thermistor. A thermistor is a resistor whose resistance changes with temperature. This changing resistance blocks some or a lot of the voltage flowing thru’ it.
What does it mean when your coolant sensor says p0118?
A code P0118 may mean that one or more of the following has happened: An open in the ground circuit between the ECT sensor and the PCM A short in the voltage feed between the sensor and the PCM A bad temperature sensor (shorted internally) First, if you have access to a scan tool, check the reading of the coolant sensor.
When does the coolant temperature warning light turn on?
The coolant temperature warning light turns on when your engine is sensed to be too hot and is at risk of damage from overheating. Is it safe to drive with the coolant temperature warning light on?

What kind of temperature sensors do Ford use?
Delphi temperature sensors are built with the latest OE technology; Delphi temperature sensors use durable, one-piece design; Delphi temperature sensors are impervious to electrical noise and interference. The only parts recommended by Ford Motor Company for Ford, Lincoln and Mercury vehicles.
How are coolant temperature sensors used in cars?
NTK’s Engine Coolant Temperature Sensors are manufactured to operational performance standards to meet or exceed OE fit, form and function to ensure proper engine operating temperature. Engine Coolant Temperature (ECT) Sensors measure the temperature of the coolant.
