Como trocar sensor de temperatura externa do Citroen C3.Problema com sensor de temperatura marcando temperatura alta ou baixa The temperature gauge bars cover a wide range of temperature. 2 bars would light at 70°C, 3 bars at 80°C to over 96°C - it would not go over this when tested due to the fan cutting in. Keep an eye on the coolant level since it may take a few days for all the air to come out. Replace if necessary. Check that the coolant temperature (ECT) sensor type is correct. Replace if necessary. Citroen C3 2nd gen. - ALL MODELS FROM 09/2006. Issue - Irregular sound from the gear belt space. Cause - Water entering the gear belt covers causes corrosion.

Easy EV home charger install (74kW) Hello forum members, hope that this message finds you all in good health during these days of pandemic. Attention shifted to engine control. A mechanic tried a new inlet manifold air pressure (MAP) sensor. This seemed to make some difference to the warm-up and cut-out problems, but the mid-range choking persisted. And I now think the improvement was coincidence. I kept trying: cleaning and checking sensor plugs and sockets, wiring, the ECU plugs. Hi Guru, Thanks for your response. Point 1: Unfortunately my vehicle is in South Africa so the reg no wont work. I did look at the site and it refers to 2 different square connection 2 pin green coolant sensors and a third option of a rectangular blue 3 pin sensor. Good morning to all I tinkered with the C3 this weekend regarding the temp problem and the fan. I removed the sensor in the expansion tank for the coolant and got the red light flashing on the temp indication on the dash , checked the connection on the temp sensor looked OK but still the all the lights come on after a few seconds of starting P2033 is an OBD-II generic code for the exhaust gas temperature sensor circuit high bank 1 sensor 2 to the engine control module (ECM). This means the sensor signal voltage is shorted high on bank 1 sensor 2, indicating the temperature sensor is out of specified temperature range for a normal exhaust after the particulate filter on diesel engines.
