Thread: Fuel Temp Switch

Hi All, my question is to do with the fuel temp sender switch in the fuel line of a 3,5 V8 D1. What is the effect on fuel consumption and the general running of the veh. if this switch is faulty or even disconnected.
Thanks Bob

This is what troubleshooting the 14CUX says.

Fuel Temperature Sensor (aka: "thermistor" or "thermally sensitive resistor") (see fuel rail photo above)

The Fuel Temperature Sensor is threaded into a boss on the fuel rail, forward of the plenum. (See the fuel rail photograph above.) Note: this sensor does NOT contact fuel, and thus it can be removed without gasoline leakage. The information provided by this sensor is mainly of interest when the engine is being started. If the fuel in the fuel rail is already hot, the ECU "knows" a hot engine is being re-started, and can adjust the mixture accordingly.

The Fuel Temperature Sensor on our example system is marked "Lucas", "Made in UK", and "73273D". It has two terminals.

If you PM your email address I can email the entire article to you and you will know more than you want to about 14CUX.

I do not know if that is the whole story as I seem to recall that the temp sensoralos has a role in trimming the mixture in a non cat car.
