Hi looks a good forum.
Focus 1.6 2003
Just started having problems starting from cold, turns will not fire, press throttle down, fires, bit lumpy then ok. After about 10 mins of driving fan comes on & air con fan. Car runs ok though.

I have been told this could be a problem with the E.C.U. & rather than may for a diagnostic, it may be worth changing the cylinder head temp unit.
I am quite happy to try that. Can anyone tell where it is? & are there any other thoughts on what the problem could be.
Thanks in advance.

I have been advised to change the C H T (Cylinder Head temp sender).
Can anyone tell where this is, I have been told it has 2 wires brown/white + white/violet.

I just cannot find it.

You have the right colours, the sensor is on the n/s/f of the cylinder head usually located in the outlet of the thermostat housing, If you remove it be prepared for coolant spillage and toppping up afterwards.

Hope this helps

Thanks for that,
Do you know what the sensor is thats at the back of the engine, (looking from the front of the car) that is in the middle, 2 wires brown & white. This is the sensor that the spares shop said they sell a lot of.
It hasnt completly got rid of the starting problem, but it has stopped the fans coming on.
Maybe I had 2 faulty sensors.
