I have a 1998'Ford Explorer and half the dash lights are out and all pod a sudden my speedometer just quit. Need to know what fuses would go to these, so I can try that. Ty


Sorry but it's not a fuse problem . There is not a fuse just for the speedometer . The microprocessor inside the instrument cluster determines where the speedometer needle points , just like the fuel gauge , tachometer etc... Having the vehicle checked for DTC'S would be the proper step to take .
Vehicle Speed Signal
The vehicle speed signal is generated by the rear anti-lock brake sensor and sent to the 4-wheel anti-lock brake system (4WABS) module. The 4WABS module sends the vehicle speed signal via circuit 679 (GY/BK) to all systems which require a vehicle speed signal input.
Speedometer
The electronic speedometer receives a speed signal from the 4WABS module.

  • The Speedometer/Odometer Is Inoperative
  • Circuitry.
  • Speedometer.
  • GO to Pinpoint Test E .

No where in this factory diagnostic step does it say to check a fuse !

PINPOINT TEST E: THE SPEEDOMETER/ODOMETER IS INOPERATIVE CONDITIONS DETAILS/RESULTS/ACTIONS E1 CHECK THE VOLTAGE TO THE INSTRUMENT CLUSTER
Instrument Cluster
Measure the voltage between instrument cluster C288-7, circuit 1001 (WH/YE), and ground.
  • Is the voltage greater than 10 volts?
Yes GO to E2 .

No REPAIR circuit 1001 (WH/YE). TEST the system for normal operation.
E2 CHECK THE INSTRUMENT CLUSTER PRINTED CIRCUIT
Instrument Cluster
NOTE: Measurements must be made to the speedometer gauge pins that are inside the instrument cluster printed circuit clips.
    Measure the resistance between the speedometer pins (which can be seen in the middle of the instrument cluster printed circuit clips) and the corresponding instrument cluster terminal. Refer to the table for the pin and terminal assignments.
    Instrument Cluster Terminal Speedometer Gauge Pin C286-13 C287-1 S C287-2 G C288-7 BATT
    .

  • Are the resistances less than 1 ohm?
Yes GO to E3 .

No INSTALL a new instrument cluster printed circuit. REFER to Instrument Cluster Printed Circuit . TEST the system for normal operation.
Your best bet , take it to a qualified repair shop

Odometer,speed odometer,and trip not working.replace speed sensor.


Speedometer
The speedometer is an analog gauge that is located in the instrument cluster. The PCM/VCM receives an analog input from the vehicle speed sensor and converts it to a digital signal containing 4,000 pulses per mile (PPM) for the instrument cluster.
The PCM/VCM sends this digital output (4,000 PPM) to the instrument cluster on a designated circuit. These pulses can be measured in Hertz (Hz) using a digital multimeter (DMM) on the AC scale. The PCM/VCM calibration is matched to the final drive and tire size of each vehicle. If the final drive or tire size is changed for any reason, the PCM/VCM must be updated in order to match the new final drive or tire size. If not, the signal will not be accurate for proper speedometer/odometer operation. An incorrect signal can affect the antilock brakes and the cruise control systems.
The speedometer system consists of the instrument cluster, vehicle speed sensor (VSS), PCM/VCM and related wiring. The VSS is a permanent magnet signal generator that sends an analog signal proportional to the propeller shaft speed to the PCM/VCM. The VSS mounts to the transmission tailshaft extension housing on 2-wheel drive (2WD) models and the transfer case output shaft housing on 4-wheel drive (4WD) models.
Repairs to the instrument cluster can only be performed by an authorized instrument cluster service center.

Diagnostic Aids
• An intermittent in the vehicle speed sensor (VSS) circuit may cause an inaccurate speedometer. Refer to Testing for Intermittent Conditions and Poor Connections in Wiring Systems.
• Check for the following DTCs:
- DTC P0502 Vehicle Speed Sensor (VSS) Circuit Low Input and DTC P0503 Vehicle Speed Sensor (VSS) Circuit Intermittent in Automatic Transmission - 4L60-E
- DTC P0500 Vehicle Speed Sensor (VSS) Circuit in Engine Controls - 4.3L

Important: If the instrument cluster is completely inoperative, refer to Instrument Cluster Inoperative .
Install a scan tool.
Raise the vehicles drive wheels. Refer to Lifting and Jacking the Vehicle in General Information.
Start the engine.
Place the transmission into drive for automatic transmission and third gear for manual transmission.
Compare the displayed vehicle speed on the Instrument Cluster with the monitored speed on the scan tool.
Does the vehicles speedometer and the scan tool both display 0 km/h (0 mph)?

YES - Go to Step 4
NO - Go to Step 3

Go to Testing for Intermittent Conditions and Poor Connections in Wiring Systems
Go to Step 4

Turn OFF the ignition.
Disconnect the in line connector C101.
Turn ON the ignition.
Test the vehicle speed output (4K) circuit voltage from the in line connector C101 (female side of connector) to a good ground using the DMM J 39200 . Refer to Circuit Testing in Wiring Systems.
Does the DMM display a voltage greater than the specified value?
9.5V
YES - Go to Step 8
No - Go to Step 5

Turn OFF the ignition.
Remove the instrument cluster. Refer to Instrument Cluster Replacement
Test the continuity from the vehicle speed sensor signal (4K) circuit at the instrument cluster electrical connector to the in line connector C101. Refer to Testing for Continuity in Wiring Systems.
Does the DMM display continuity?
--
YES - Go to Step 6
NO - Go to Step 10

Test the instrument cluster harness connector for a poor connection to the instrument cluster. Refer to Testing for Intermittent Conditions and Poor Connections and Wiring Repairs in Wiring Systems.
Did you find and correct the condition?
--
YES - Go to Step 17
NO - Go to Step 16
8
Turn OFF the ignition.
Disconnect the PCM/VCM harness connector which contains the vehicle speed sensor signal circuit. Refer to Powertrain Control Module Replacement/Programming in Engine Controls - 2.2L or VCM Replacement/Programming in Engine Controls - 4.3L.
Test the continuity of the vehicle speed sensor signal (4K) circuit from the PCM/VCM harness connector to the in line connector C101 using the DMM J 39200 . Refer to Testing for Continuity in Wiring Systems.

YES - Go to Step 9
NO - Go to Step 12
have you ever used a diagnostic trouble flow test chart ? Let me know if you make it this far and then I will send the last 9 steps . It's either a wiring problem or instrument cluster or PCM is bad . And if the PCM is replaced it will need progamming . Dealer only .

2001 Buick Century Limited speedometer problem, Speedometer not working but odomitor ok. Is there a fuse?


if the odometer is working then the problem is with the speedometer head unit as the odometer gets its information from the same source as the speedometer. you can have the speedometer head checked and fixed if its fixable.

More info needed. Is this a hatch back, sedan, or CRX? Is the odometer mechanical [old style] or digital [LCD numbers] The vehicle speed sensor [located behind the speedometer in the instrument cluster] drives both the speedometer and the odometer [mileage meter]. It sounds like an electric problem in the instrument cluster. Remove the instrument cluster and take it to your local speedometer repair shop. Look in the yellow pages for them. Or simply buy and install a used instrument cluster from a junk yard.

Digital speedometer in my 1990 Taurus Lx sits at 0 and doesnt read but my rpms and gas meter still read.


either your instrument cluster is faulty and has a short or you need to replace your vehicle speed sensor.

ps not your trans speed sensor vehicle speed sensor


if it helps please give me a good rating

Speedometer stopped working.


The speed sensors will not fix it. This is something that these cars will do in hot weather. The instrument cluster need to be removed and the contacts from the printed circuit to the connector need to be cleaned. Over time they will lose contact and affect the fuel gauge or speedometer. You may have to replace the speedo cluster. Sometimes if you hit the dash just above the fuel gauge it will start working too. Been there done that, fixed mine as the printed circuit was coming apart at the harness connector.
