Where can i find the temperature sensor on a citroen c3?


Answers:
they're threaded into the bell-housing where the thermostat goes. just follow the upper radiator hose to where it enters the engine and find a copper bolt with wires coming out of the back. that's the temp sensor.
most sensors are on the top of the motor near the back passenger side of the motor .. follow the top radiator hose to the top of the motor and look right around there and you should see it with a wire coming from it
You generally find with most French cars, it is a small bobble type lump on the underside of the passenger door mirror (outside temp). Engine coolant temp sensor will be on the side of the engine block.

Not knowing exactly which temp sensor you mean.
