Volvo 240 2.0 1990 Fuel Sensor/Gauge
 

Hi there
have recently purchased this wonderful car and am so impressed. My only concern is that once the fuel gauge gets down to approx. quarter of a tank the gauge goes right down passed the red mark and stays there.

As this car is new to me lm really not sure how much fuel l have left in the tank, havent even had time to establish the total mileage for say £30 worth of fuel.

So my question, could someone please advise on how, where and approx. costs to have the fuel sensor replaced etc

Thanks in advance for your advice

Replacement fuel sensor comes complete with lifter pump and pipework £240 Plus Vat from memory. My 1993 240 gauge is not linear and does drop quite quickly below a quarter but it does not just fall to zero. There is a wiper arm type sweeped resistor track that produces the current for the gauge but to remove the whole tank insert to see if you can bend the arm a bit would be a nighmare, trust me. Ples you will probabley break the pipes off and need a new one anyway. First check the volage at the connector just inside the inspection cover when the tank is showing empty and tell me what voltage you have. And when you fill it right up does the gauge say FULL. Regards Peter

Hi Peter
Thanks for your response. The approx cost you mentioned is more than l paid for the car itself...lol

I am a complete novice in respect to the worknig of cars etc so checking the voltage as you mentioned isnt something l would do.

In respect to your question does the fule gauge go up when filling up...yes it does

I feel that it is something l will have to live with and just make sure that l have the petrol can in the boot.

Thanks again for your response, it certainly answered my question and has given me food for thought

If it goes to full then it is not a connection problem as this is the lwere resistance end of the pot. Either the track is worn out or the wiper is too light. Then are a fortune to change so just fill the tank up and press the mileometer and when you get to 220/240 fill up again. Regards Peter
