Why is the odometer and Speedo not working?

Why is the odometer and Speedo not working?

Neither the Speedo, odometer, nor cruise controls are working. I changed out the inst. cluster and the vss. It does not have a mechanical speed sensor, electric magnetic. I originally thought it was the cluster so I changed that, no good. A few weeks later the service engine light came on, checked for codes and got 24. I than changed the vss.

Why does my Speedo reset to 0 / mph?

Speedo reset to 0/mph, it’s been stuck at 30/mph for months. I would’ve never thought it either, 3 clusters and hours of wire checking and it’s a brake fuse.

Where is the VSS sensor on a GM Truck?

To change the ratio on an 89 a reduction box was used on the speedometer cable at the trans or transfer case. I believe 1992 was the first year GM used a DRAC in the trucks. The 89 still used a speedo cable and the vss sensor was located in the speedo head.

Why is my Ford Mk1 Speedo not working?

My Mk1 had the exact same problem as yours. Only the speedo was affected, everything else worked. It had a new VSS and instrument cluster which failed to fix it. It was eventually traced to the VSS cable chafing on the gear linkage, so before you go shelling out £££s for new parts it’s worth checking that first.

What to do if your speedometer is not working?

If the speedometer on your automatic transmission Ford vehicle is not working, check the tail end of the transmission to see if the vehicle speed sensor (VSS) is securely attached. Another symptom of a bad speed sensor is sluggish automatic transmission shifting.

What happens if your speed sensor is bad?

Another symptom of a bad speed sensor is sluggish automatic transmission shifting. The vehicle’s computer also uses the speed sensor signal to control emissions and cruise control. Replacing the VSS in this 1992 Ford Ranger made quite a difference in its get up an go. Loading…

What happens when the speedometer on a Ford Falcon stops working?

One of the most inconvenient things that can happen to your Falcon is when the speedometer stops working. You don’t really realize how much you look at the thing until it’s just always sitting at 0 MPH while driving down the road.

How to check the odometer on a GM Truck?

OK, you need to check the signal first at the VSS, then at the PCM. The VSS is a pulse generator which produces an analog A/C signal. Use a volt meter set to A/C voltage. Unplug the sensor and hook up the meter to the 2 terminals on the sensor.

Is the speedo on my old cruiser working?

Yes this is your old cruiser. The car is a pleasure to drive so this speedo problem is a real pain as no MOT no Drive . There does not appear to be any gizmo on the gearbox. In fact (like SC) I think the bits I removed from behind the speedo were to convert KMH tp MPH.

What to do if your Speedo is not working?

Test across for continuity. Otherwise, try each of the fixing screws for continuity to your sender plug, only those on the PCB though as the others only work the cam belt light. They cannot fail the car if the speedo does not work. It has to be illegible, obviously damaged or not illuminated.

Why is my Speedo stuck at 30 mph?

If you have a trailer wiring or the brake switch goes bad (my case) the blown brake fuse will kill the brake light, cruise, brake unit, AND the speedo servos. I replaced the fuse hit the key and bam! Speedo reset to 0/mph, it’s been stuck at 30/mph for months.

Why is there no speedo on my 88-91 truck?

But on the 88-91 trucks the speedo is controlled by the “BRAKE” fuse!! I noticed people riding my tail lately and found no brake lights. Fuse was blown. If you have a trailer wiring or the brake switch goes bad (my case) the blown brake fuse will kill the brake light, cruise, brake unit, AND the speedo servos.

Why is my speedometer not working on my Silverado?

I bet they plugged in the speed sensor connectors to the wrong speed sensors. They easily reach each other, and can easily of been swapped, Been there done that, and got a t-shirt.. ^^^^There is the best answer you will find on this site.

How does the VSS work on the speedometer?

If the transmission is shifting okey and the cruise control works the VSS is most likely producing a signel. You can measure that that the connection plug with a DVM. The VSS signel is processed by the speedometer head in a lot of cases. The signel is amplified/ squared up with a Schmidt trigger flip flop; and drives the speedometer stepper motor.

Where is the speed sensor on a Speedo?

There are three wires attached to the back of the speedo which I assume are part of the after-market immobiliser. These wires run to a small black box and a further wire runs from this box to the loom. At the loom I found two wires had been cut, soldered together and joined to a fourth wire leading to this little black box.

What to do if your Toyota Hilux speedometer is not working?

If your Toyota Hilux’s speedometer is not working, the first place to go would be to check the service engine soon light (if applicable). Now, take it out and see if the cruise control still works. If it does, that’s a pretty good indication that the vehicle speed sensor is just fine. If it doesn’t, it’s time to take a look at it.

What should I do if my speedometer is not working?

(d) Check that there is voltage change from approx. 0 V to 11 V or more between terminal 3 and 2. of the speed sensor shaft. If operation is not as specified, replace the sensor.

How to check the odometer on a Speedo?

1, check to see if the odometer works while the speedo doesn’t. I found mine after the needle stopped for bore than the usual 400 yards and saw the counters turning. Test across the tracks on the PCB. 2, Run your test wires to the test plug you made up and have that fitted to the vehicle while you go for a spin and see if you get the same pulses.

Why is the speedometer not working on my Kia Rio?

You don’t really realize how much you look at the thing until it’s just always sitting at 0 MPH while driving down the road. If your Kia Rio’s speedometer is not working, it’s usually going to be caused by an issue with the VSS (vehicle speed sensor), or a bad ECU. The VSS is usually not very expensive, and they are not that difficult to replace.

Can a speedometer be used as an indicator?

OR: * If neither a voltmeter nor frequency counter is available, vehicle speed control may be used as a good indicator. If it works normally, then the speedometer module is at least receiving a speed input signal and the wiring and sensor & tone ring can be assumed to be good.

How does the speedometer work on a Ram 1500?

They are electronic components that read a series of electronic pulses that have been converted via the vehicle’s computer into readable data such as the speed. The pulses are delivered through a rotation sensor in the transmission that calculates the driveshaft’s average rotational speed.

How does the speedometer work on a Ford F250?

The VSS is one part of a system of sensors that helps keep you safe (traction control, ABS, cruise control). A modern vehicle’s speedometer takes the input from the Vehicle Speed Sensor and sends that data to the ECU. The ECU is programmed with your F250’s gear ratios and stock tire height.

Is the odometer on my 91 Chevy working?

What do you do when your instrument cluster doesn’t work?

Also when you drive the car, the speedometer and the rpm gauge doesn’t move. Everything light wise works. Everything works except the rpm, speedometer, temperature and gas gauge. All fuses and relays are good. I’ve even changed the instrument cluster and the BCM. Still none of the gauges work.

What does an instrument cluster on a car do?

An instrument clusteris the collection of gauges, dials and lights right above the steering wheel that tell you what’s going on in your vehicle. Generally, your car’s instrument clusterwill last the lifetime of the car and you’ll never have a problem with any of them.

What happens to the odometer when you turn off the gas?

The car’s odometer cluster, including fuel guage, speedometer, rpm meter, temperature etc becomes dead sometime (while driving or when I begin driving) and when this is dead the car starts loosing accelerations beyond certain speed. If I push the gas pedal hard, nothing happens, it seems like the car has been turned off.
