Engine overheat and boiled over

Hi and thanks no I've not changed the green sensor as I wasn't sure if it was this one or the blue one on the side off engine that is causing the fault I started the car after sitting off for 4 hrs and the warning comes up still so I take it one of these sensors are faulty how to test which one it is or bite the bullet and buy both but I'm still worried there isn't water in the radiator as top hose feels soft and no heat in either radiator pipes

Hi there ive not changed the sensor yet as this fault only happened after I bridged out the sensor do c3 electronics store and show faults as I think I've tripped the cpu by bridging the switch out or do I just change the sensor as when sensor wired up and I start the car cold the fault comes up then goes away and only the coolant light on thanks everyone for the help

There is no blue sensor on this model so it's the green one on the thermostat housing or if you triger faults do they need taken of with a fault analyser as I know have a engine overheat and a pollen filter fault as I disconnected the other green plug at sensor blocks the pollen filter and the gearbox lamp is now on the dash thanks again everyone

Gearbox lamp on a manual?

Are you sure it is a gearbox lamp?

Other green plug at the sensor block?

What is your VIN?

Hi sorry I checked its the engine light and the coolant light that are on in the dash and both with a fault that flash up when car is started and say engine overheat stop and pollen filter fault then writing goes away doesn't come back on while cars running but both lights on dash stay on thanks

On a 2007 1.4 petrol desire? Hmm I don't know what's going on here.

Hi there me again sorry but I have rectified the leaking coolant and bled system and car runs OK but I disconnected two green sensor jack plugs and bridged out the green thermostat lead and then put the back to how they where now when o start the car I have 3 beeps a few second after start and engine overheat and coolant light come on also the antipollution fault so engine light and coolant light on after the initial start up the two faults seem to go away but the lights stay on and car drives normally do these faults need cleared to get rid of them or should I just change the thermostat sensor thanks

Can you please take photos of the green connectors and the lights on your dash?

Hi I will take photos of the dash in various states and both sensors today and thanks for the help it's appreciated
