You should be able to measure some current flowing through the wire even when the bulb is dark. When the fuel is no longer high enough to bathe the sensor, the sensor becomes hot from the current flow, it conducts better, and then the bulb glows. If you don't see several mA flowing when the ignition is on, you have a broken connection. |
Re: Fuel warning light never come on
Thank you all for your replies.
The indicator used to come on when the fuel was low, now it does not come on even though I am below the red mark. I had planned to run it dry but the jackasses in Vancouver like to crank up the price of gas on weekends so I had to fill up or face a 12c/litter increase. The current test sounds logical. So where is the best place to measure the current ? At the bulb end ? Or simply look for a voltage drop across the bulb ? Is there a separate circuit going all the way to the tank just for the Low Fuel light ? Is this a normal way to do this ? Is the lamp test at ignition on supposed to illuminate the Low Fuel lamp ?

Re: Fuel warning light never come on
Several months ago I heard that Shell fuels were causing problems with
Chrysler products low fuel sensor system. I had only heard about this on newer vehicles and Shell had agreed to cover the cost of repairs. I don't know if any reshearch was done to see if this problem effect other vehicles and I don't know how Chrysler's low fuel warning system works. I guess this could effect older Hondas or other vehicles too. Just a thought and an opportunity to pont fingers at gas companies, especially when they up the cost of gas just before the weekend.

The first thing that I would do is run it until it is on the empty mark and pull into a gas station with a gas can. Leave it running until it starts running out of gas. The engine will run poorly for several seconds. Keep an eye on the light. When the engine starts to sputter--turn off the engine and pour the gas from can into tank. Pull up to the pump and fill it up. If the light does not come on, try changing the bulb before you do anything else. That bulb is over 8 years old. |
