How to test the Jaguar coolant temperature sensor?
Use a bit of wire, paperclip, etc. and plug one end each into the harness connector sockets. Doing this “fools” the ECU into thinking the engine is hot, since there is now no (or minimal resistance) measured. The ECU will not add pulse width correction to the injectors…so no additional fueling is supplied.
Where is the engine coolant temperature sensor ( ECT )?
ECT is No3 in the pic below, update your profile to show which engine you have. thank you very much . but it has no wires ?!!!?!!! I Have Donated ! Grey plug with two wires plugs into the sensor, to the left of the inlet manifold, very easy to replace, literally 5 minutes.
Where is the CTS located on a Jaguar?
Prior to discussing failure of the CTS, or the harness wiring, we need to understand the function of the CTS…. The CTS is an important primary engine sensor, and is typically threaded into a port on the B bank thermostat housing…(for the V12 engine).
How is coolant temperature measured in an engine?
The CTS “measures” coolant temperature, as a heat resistance value, and transmits that value to the engine ECU, The value is measured in ohms resistance. The mapping table within the ECU interprets the resistance value as engine coolant temperature. A cold engine requires more fuel.
