Question about 1991 Chevrolet Lumina

Open Question

Speedometer problems also turn signal problems might be connected

My speedometer is way off it will say I'm going 90/100 when I'm maybe going 40. And you have to jimmy the turn signal thing to get it to turn on and usually hold it in place to make it stay on. What could the problem be?

SOURCE: Acually it's a 2004 Silverado Speedometer problem

Hi,

Sounds like your speed sensor (odometer sensor) is failing or failed. This sensor is found on the tranny. Best to consult your local dealership.

SOURCE: Both speedometer & tachometer not working, both reading wrong.

There was a recent class action law suit settled with GM for this exact problem. You can google gm speedometer lawsuit and get lots of information. Unforutunately for most people I think the warranty was limited to 7 years and 70,000 miles. Which isn't a lot of miles for most people.

If you car isn't covered by the warranty there is a way to "reset" the speedometer.

You can turn the ignition slowly like you are going to start the engine. There is a very small "dead" space where you will see your guage lights go off.

What you want to do is cycle the ignition switch from off to that dead space. Each time you do it your stuck speedometer will move towards zero about 10 mph. So if its stuck on 40 you will have to cycle it at least 4 times.

At first you will probably actually hit the ignition and the engine will try to start.....just release it and try it again.

I know this because I have a 04 avalanche with 80,0000 miles and it has this problem about twice a month.

Replace the speed sensor, but also make sure you clear any codes, even if none are showing up, disconnect the battery for about 1 hour. After that drive it easy for a while, so it can relearn.

There was not a recall, but there was a class action settlement where GM agreed to extend the warranty on certain vehicles for this problem. Check www.gmspeedometerrecall.com to see if you qualify.

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

Transmission speed sensor


You could have a faulty speedometer/odometer combination meter causing a false Vehicle Speed Sensor error.
My 1998 Sienna had the following symptoms:
- Speedometer and odometer failed intermittently
- The check engine light would come on and I would get a p0500 code in the OBDII.
- The cruise control would stop working at the same time the speedometer failed.
There is a speed sensor in each one of the tires and they feed the speed information to the ABS ECU. From the ABS ECU the speed signal goes to the speedometer/odometer combination meter, and from there it goes to the Engine Control Module and to the Cruise Control ECU. I could see a signal coming into the speedometer/odometer, but no signal going out. Replacing the speedometer/odometer combination meter fixed the problem.

Turn signals on 2001 Chrysler Town & Country cause dash lights to come on and speedometer & odometer quit working


I would say its probably a short or a ground problem at the turn switch or a wire in that area. you need a test light and probably a multi meater and some nohow a ground or wireing problem can even drive a master teck crasy.

2003 chevy avalanche 1500, speedometer and odometer not working at all


Being and electronic speedometer, it will surge a touch when engine first started or switch first turned on, that's normal, but the only reason it is not working while driving is most likely a faulty speed sensor. Code should tell you this with a reader.

1994 Volvo 940T Speedometer Works Intermittently


If the speedometer and odometer are not working the problem is usually lack of signal from the transmission speed sensor.
But if the cruise control works and the speedometer does not, my guess would be a problem inside the cluster.

Speedometer not working


Problems arise when there is trouble anywhere in the above mentioned functioning process. The most common ones are problems in the speed signal sensor, as a result of which the speedometer stops working. If you notice problems in gear transmission or find the 'check engine' light on, it is because of a faulty speed signal sensor. In case of your speedometer using the 'eddy current' technology, there could be a trouble with the connecting cable which causes this problem. Ticking noises are a sign of this problem. In either case, you will need to replace the cable or the speed sensors to solve your problem.

1993 toyota camry le 4cl speedometer wount work?


It can be faulty vehicle speed sensor .The sensor connects to the differential.The sensor in the transmission that tells the instrument panel how fast the transmission is turning. Sometimes that sensor breaks.
There is a speed sensor on the transmission that sends a signal to the
speedometer control on the back of the instrument cluster, and diagnosis is
pretty straightforward. The On-board Diagnostics Generation II (OBD II)
scan tools used by professional technicians should have the ability to read
the signal generated by the transmission speed sensor and therefore check
the function of the speed sensor. Even if the technician's scan tool does
not have this capability, the sensor can be checked with a volt meter at the
sensor itself.

If the sensor is putting out the proper signal, then the next step would be
to check the wiring between the speed sensor and the speedometer control by
checking the signal at the wire harness at the speedometer control. If the
signal is good, then the speedometer control is bad, and if the signal is
bad, then the wiring between the sensor and speedometer control is bad. The
most time confusing part of doing all these checks would be removing the
instrument cluster to get at the speedometer control, about a half-hour
total for all the checks.----------
If the needle moves you have a broken pinion or counter gear.If not, then I would replace both speedometer cables.---------------Thank you.

Speedometer and Blinkers don't work


Believe it or not but I think your hazzards are on a seperate fuse. If you had lost just your turn signals I would say probably a bad flasher but the speedometer is actually a little electric motor now, not a cable driven thing like years ago so it's probably just a fuse. Now, why did the fuse blow? Trailer wiring shorted? Corrosion near the tail lights? You been mudding it lately? Or maybe just a corroded tail light socket. Check all your lights afterwards. Hope this helps

Speedometer Stops


Most cars Speedometer cable connect to one of the front wheels, but you said your speedometer sometimes stop then your steering wheel will go stiff, I think you should fix or change your speedometer cable, maybe the cable broken inside. Fix it as soon as possible for your safety.

Speedometer cable has two parts, one is outside cable, mounted and connect to both speedometer and wheel.

The other one is an inside steel cable, outside cable protects the inside cable, because the inside cable turns as soon as you move the car. It is directly connect to the wheel gears and the speedometer inside.

If your car has speedometer cable, I think you need check it right away.

Your steering wheel sometimes stiff, you also need to check your power steering fluid level, sometimes cause this kind problem.

Hope this can help you and if you have more questions, please use whatever the Fixya allowed, contact me to discuss this matter and others. Thank you.
