C1 petrol gauge not moving - Cars & Trucks

Hi,it must be that the gauge or sender unit are faulty,check sender unit first.

Hi Singo the light and gauge are seperate systems that's why they are reading wrong. It's most likely the sensor in the tank of worst case an ECU fault. You will need someone to look at it for you because Renault electrical systems are very temperament and a wrong move could cause other more serious problems. Regards Jim...

located in the interior fuse box , most likely to have other components on the same fuse so check your owners hand book

Possible that the wires leading to your petrol gauge are loose on the fixings, if you can see where the gauge is on the side of the tank you may be able to see if this is true, i dont know this car sorry so thats all i can say!
Hope this helps,

The best idea is to change broken petrol gauge with a new one or in good condition one petrol gauge !

suspect it could be tank unit this is similar to a ball valve in a toilet .float arm moves up or down depending on fuel level sends reading to gauge situated in fuel tank sometimes part of the fuel pump

this is caused by the gas gauge sending unit in the gas tank being an open circuit, pull the tank and replace it.

do you know that petrol gauge is a sort of volt meter.there are five things requir to operate it.1st of all see to it that movement of gauge is working.give 1.5v of a battery directly to gauge for amoment if gauge doesn't move change the -ve to +ve even then it doesn't move it means gauge itself is faulty.if it moved look out for a wirewound resistor in fuel tank.if it is open then gauge will not work.if that is good look for voltage across resistor normally 12v are given.if 12 volts are there then look out for flot.connect a voltmeter to gauge,move the flot by hand very slowly and see if the varition in volt meter if it is not there then look out for connecting wires from gauge to fuel tank.i think you can do it now

Sounds like the Fuel sender unit in the fuel tank needs replacing however you may want to check that the electrical plugs are contacting properly,Check that the gauge is working by putting a piece of wire from the sender unit wire to the chassis,at the fuel tank sender unit plug,Turn ignition on while watching gauge if it moves toward fill turn ignition off and remove wire to chassis.If gauge moves it means from the fuel tank to fuel gauge is intact and not your problem.
