My 91 940se speedo has 2 quirks, start driving the needle lays on the peg then jumps to 70 stays there until i increase speed then the needle pegs and stays there until iclose the ignition switch. Next drive cycle same thing. I replaced the speed sensor in the diff a yr. ago which solved a myriad of speedo problems until this started.A couple of days ago.

Try shifting the transmission to neutral and try starting the engine, if it starts, the gear position sensor is bad, which is very common on this car.
Or, the starter may be bad, not common, but possible!

if you can buy a different car do it. this volvo is old and it might start to have weird electrical problems that may be hard and expensive to fix. Has it been running ok now?

SOURCE: speedometer erratic/intermittent

I don't know what is causing this problem, but I know phil140701's answer is completely wrong on two counts. First, 740 Volvos starting at least in 1986 have electronic speedometers and no cable. There is an electronic sensor on the differential which sends a signal to the speedometer cluster. Second, if it were strictly mechanical with a cable then the voltage regulator could have no effect on it at all.

1991 Volvo 940SE Speedo Problem


The symptoms you describe point to a loose or cracked speedometer cable. The cable likely needs to be replaced.

I have 03 Yukon Denali XL. When I drive longer than an hour on highway all of sudden all the warnig lights comes on, goes off a minuite later after 2 seconds black out. Reapeats same problem every 3 to 5...


Sounds like possibly a faulty ignition switch, They will cause symptoms very similar to that. Another thing 2001-2003s were known for are bad instrument panel clusters (dash assembly) usually the speedo gets pegged at a certain speed and stays there.

Speedometer is pegged full scale with engine off and on.


free wiring diagram will take some digging if at all posible but I can tell you that the vehicle"speed sensor" gives the computer "data" and the computer tells the motorized electric speedo to move. dead battery and bad connections freak the computer out and sometimes peg the gauges. then they stay there after the connections are fixed. this doesnt mean the speedo or any thing is ruined--just need to reset it. I think on cavalier you can hold the trip reset button in and turn the key on and it will go into a self test mode bringing things back to normal.I THINK thats how that one works--try it. if not there is a funtion in the chevy handheld computer to do it. Hope I helped. Thanks

Speedometer reading fluctuates


IMHO, I think that the broken cable is what is causing the problems. It "confuses" the programing of the CPU or computer.

Speedo is pegged at 120 won't move?


some times the needle will jump when key is turned on or the cluster is defective, try to use a strong pen sized magnet to pull the needle back to 0 or remove the cluster and turn it over to see if the needle will fall back to 0, you could remove the lens and move it to 0 with your finger. if all that dont work i would test the cluster and repair it or replace it
