Where is the ECT Sensor located?

Hi,

The BT50 isn't offered in the US, but I will try my best to help. I need confirmation on the engine size. Is it a 4-cylinder or a 3.0L V6? Also, is it a diesel?

I will try cross-referencing it with the Ford Ranger to see if anything helps.

Take care,

Joe

Hello,

The temperature gauge on instrument cluster receives its information from the ECM
(Engine Control Module) via CAN network
I would suggest first checking live data for the ECT (Engine Coolant Temperature) sensor in the ECM using a suitable diagnostic tool. This is to check that the ECM is receiving a plausible signal from the ECT sensor.

With ignition on and engine cold, stood over night, the ECT data should display ambient temperature.

Pin out from ECT sensor to ECM connector A

Pin 1, blue/orange wire to ECM pin A67
Pin 2, brown/yellow wire to ECM pin A56

I have looked in all my disposable technical information regarding the location of the ECT sensor.
None list the location. Below, in image 2, is where I believe the sensor to be at, near the outlet pipe to the radiator.

Input / Output Check Mode for instrument cluster
See image 1 below for related codes
†This function allows checking the input and output circuits of the instrument cluster. It
can be activated in the following way:
1. Press and hold the odometer/tripmeter switch, and turn the ignition switch to the ON
position.
2. Continue holding the odometer/tripmeter switch for approx. 5 s. until test is
displayed on the LCD.
3. Release the odometer/tripmeter switch within 3 s after test is displayed.
4. When the odometer/tripmeter indicates check code 00, push the odometer/tripmeter
switch to select a check code.
5. Inspect the check codes according to the W/M.

This technical information covers the WL-C 2.5 16V engine but as the 3.0 engine is just a larger version so the information will be relevant

I hope this helps.

Cheers, Boris

Boris, thank you as well from me. It's great to know you are there to help with these.

Take care,
