Question about 2005 Ford Five Hundred

1 Answer

Analog gauges drop to ''0'' shortly after start-up & return to norm

2005 Ford 500, limited. Shortly after start-up the analog gauges will drop to 0, after 2 to 3 seconds they will restore to normal. This does not happen with every start-up. After dark when the lights are on the dash lights will go out when this happens.

    My analog gauges drop to zero and vibrate at the zero mark for about 3 seconds and then just start working again. This does not effect the dash lights or the LED odometer. It doesn't happen everytime I drive, but when it does start, it seems to keep following this same pattern.

There was a write up in The Plain Dealer in Cleveland, Ohio back November 2007, which was a month after I purchased my '05 500. You will have to take it back to the Ford dealership (if purchased from Ford) and have them replace for the cluster panel. Since I had just purchased this piece of junk a few weeks earlier, I argued that I should not have to pay for this, and they finally agreed. I have had nothing but headaches from this car since I bought it. Right now, a year after I've had it, the starter has gone out on it, and, of course, my warranty just ran out. I would not recommend that anyone buy a Ford -- EVER!!!

2006 f-250 everything in dash go out then later come back on again later,speedo,tach,gauges,all drop to 0,is it a short,delayed fuse,or instrument cluster?

CHeck the earth returns on the instrument cluster. The behavior points to a loose electrical connection rather than a short or fuse.

P2285 code 6.0 litre ford deisel long cranking before starting after starts runs great but oil pressure gauge drops at idle

bad bearings on crank or worn oil pump. Pressure will be up when cold, but will drop when engine warms up. Check for knock in lower end. If so, bad crank bearings.

All your gauges are working. The gas gauge Is also working. When you fill it, you will fill over the limit the fuel level switch will go by a couple of gallons. So the gauge will not drop for a few miles. until you use up the excess fuel

2002 F150 Radio went dead, noticed voltage dropping almost completely. Turned off heat and lights. Shortly afterwards, voltage returns back to normal. Everything is operational. I let run for 15 min to...

The gauge in your truck reads the alternator output. Following are the possible causes:

1. Belt is slipping
2. Battery is shorted
3. Poor connection at battery or to frame
4. Alternator failing

The fact that it came back after turning off the heat and lights, I suspect the belt, and would start there.

2003 F-250 instrument cluster...

it sounds like you are getting a surge of voltage from your alternator/generator. Very strange.

the dealer can run a diagnostic test & pull fault codes or you can try this. If this helps, please report back & rate as fixya. Thanks. I am curious what you find as root cause. Good luck.

Instrument Cluster Self-Diagnostic Mode
To enter the instrument cluster self diagnostic mode with the engine off, depress and hold the odometer reset button. Turn the ignition switch to the RUN position and hold until the gauges sweep (within five to eight seconds). Depress the reset button once to advance to each stage of the self-test.
Turn the ignition to the OFF position to exit the instrument cluster self-diagnostic mode. If no DTCs related to the concern are retrieved, proceed to the Symptom Chart to continue diagnostics.

Instrument Cluster Self-Diagnostic Mode Odometer display Description GAGE Carries out gauge sweep of all gauges, then displays the present gauge values. Also carries out the check sum test on ROM and EEPROM. All segments illuminated. Illuminates all odometer segments. bulb Illuminates all micro-controlled lamps and LEDs. r #### Returns to normal operation of all micro-controlled lamps and LEDs and displays hexadecimal value for ROM level (used when requesting assistance from the hotline). nr#### Displays hexidecimal ROM level and type as stored in non-volatile memory (NVM). EE ## Displays hexadecimal value for EE level (used when requesting assistance from the hotline). dt #### Displays hexadecimal code for the final manufacturing date. ###C Gas engines display last temperature gauge input value from SCP, temperature gauge will indicate present temperature. Diesel engine displays present temperature analog/digital input in decimal as a ratio, temperature gauge will indicate present temperature. dtc #### Displays a 16 bit DTC in hexidecimal format. DTCs displayed are those detected in continuous operation not during self-test. EnG Displays English speed value being input, speedometer will indicate present speed. m Displays metric speed value being input, speedometer will indicate present speed. tAc Displays the tachometer value being input to the instrument cluster. Tachometer will indicate present rpm. FUEL Displays the present analog/digital fuel level being input to the instrument cluster as a ratio.

Gas gauge will drop to empty and then go back up. Happens every so often and I know car is full of gas

If you are lucky, it is only an intermittent connector between the sender and gauge.
It will take some wire chasing if you want to try this first.

Most of the level senders (sensors) are primitive wire-wound resistors on an arc-shaped insulator.
The level change is is detected by a change of resistance which in turn varies the current passing through either an analog meter or a sensing resistor whose voltage drop is measured and displayed digitally.

The resistor type is not very reliable since it would equate to turning a volume control back and forth on an analog radio continuously which would wear it out pretty quick.

A high resistance normally is interpreted as an empty tank; therefore, an intermittent contact in the sender or in a connector will be understood as an empty tank too.
If you can watch it without wrecking your car, you will probably see that the gauge (if analog) goes way under the 'E' whereby a truly empty tank would go only gently down.

Replacing the sender is not tough, but getting to it may be a pain.
