Be the first to write a review
There are 2 types of temperature sender, Long and Short as shown in the pictures.
Please check yours prior to ordering.
Lotus original part number A117E6017S
The sensor is a thermistor which is a resistor that changes resistance value with temperature.
The ECT sensor is mounted horizontally and the water temperature gauge sensor s mounted in the same pipe vertically just below.
Normal running temperatures of 85 degrees will produce a resistance of 300 -400 ohms.
If the ECU receives a signal outside this range it will default to 60 degrees and the cooling fan will switch on
To replace the sensor disconnect the harness plug and position a container to catch coolant when the sensor is removed. Unscrew the sensor from the junction pipe.
Clean the threads of the pipe and apply Teflon tape to the thread before torqueing to just 6Nm.
Refit the plug and top up the lost coolant
This fits the following models:
- S2 K SERIES ELISE
