Re: outside temperature sensor. by GiveMeABreak » Mon Apr 05, 2021 10:23 am. Xsara Picasso Only: These sensors are available quite commonly - the original part number is: 6445F9 and costs £48.02 from Citroen - but you can google this part and pick them up quite cheaply. The screen says either "STOP: Engine Temperature Fault - Stop the vehicle" or just "Engine Fault - Repair needed". The temperature warning light is also on. Checked under the bonnet, and coolant was just under maximum - no apparent over-heating - didn't steam at all unscrewing the cap. Left it an hour to cool down completely and still got On the other hand, it could be due to a defective coolant temp sensor or a bad temperature gauge. Here is a more detailed list of the reasons why your car temperature gauge goes up and down: 1. Bad Thermostat. The thermostat is used to regulate the temperature of the coolant. If it starts to fail, it can act erratically, causing the gauge to Engine won't rev over 2000. Citroen C3 Heaters not blowing hot air. C3 Front Wiper Failure. Citroen C3 Heater Blower Failure. C3 Picasso Hub Nut Torque. 2016-2022 Citroen C3 lower fuse box layout. Easy EV home charger install (74kW) Hi there had a long trip .. 300km .. was doing 130-140km/h for about 3 hours. Then had a break for a 3 hours. Today, I was driving my mum's car, a Citroen C3 1.4 HDi from 2004, and I noticed that the coolant temperature was rising very slowly.Just as a reference, this is what the dashboard looked like (picture from different car, but for my purposes here this is not an issue; coolant temperature reading was exactly the same as in the picture below): . Hi again Peeps - our local independant Citroen garage knows of our problem with the engine overheat indicator and he is 100% convinced it is the water temp sensor which throws a wobbly every now and then. this one covers C3 2002-2009 1.4 8V (engine type TU3JP) - petrol, but if you have a different engine with 16 valves, this many not fit. The sensor for the temperature gauge is the one on the cylinder head, not far from the dipstick. How does the system that cools the engine of your C3 work? All engines have a cooling system, which works by taking the heat from the engine to the radiator. This system is quite simple, and it includes the following parts: Coolant; Radiator; Coolant pump; Temperature sensor; Thermostat; Electric fan; The engine cools thanks to the coolant, or To test this code, have a visual inspection of the location and wirings of the crank sensor. If the engine has a cam sensor, you might mistook it as the crank sensor (it is a good idea to contact ATS that can research this for you). Check the sensor wires for insulation making sure it is getting a voltage signal as shown in the wiring diagram. Hi, I ve recently got my hands on a 52 registration SX C3 1.4 petrol which is beginning to turn into a bit of a money hole. My latest problem with it is with the external temperature sensor. To cut a long story short, the aircon on the car was workin..
