There are two speed sensors for every modern car. One is at the wheel (One of the tires), the other is at the transmission. The combination is used to calculate your fuel consumption, accurate speed, etc. and is sent to the O.B.D. Computer.

Usually this is a simple fix, that one of the sensors is loose, causing intermittent problems with the speedometer/RPM's display.

If the car is still under warranty, bring it into the dealer, and they will fix it for free. Just make sure to explain that you think one of the speed sensors is faulty or loose.

My temperature gauge,Tachometer,Speedo,Fuel Tank on my 2003 Opel Astra 1.6 16v Elegance doesn't work intermittantly


connection on the back of the dash needs cleaning if you push on the dash and it all works then this is the fault. sometimes hitting it works just fine for awhile but not to hard.

My speedo on my 1993 dodge cummins quit working, i use to be albe to get up to around 80km/hr and it would work again. also my overdrive doesn't work when i speedo isn't working. any ideas.


I am no expert on this but have the same problem. Here is where I am at. I bought the truck used, needed a new PCM which after installing one from a gas job and verifying that wiring was good, bought a reman from Chrysler. Speedo still did not work even though it did with the gas PCM but was fluctuating allover. Chrysler replaced PCM and speedo started to work intermittantly. Took truck into dealer and $600. later told mechanic thought it was faulty PCM. He called Chrysler and asked them to pull one from the shelf and test. They said needed a new crankshaft speed sensor.Mechanic took truck on the road, shifted into nuetral then turned ignition back on, speedo works. Replaced crankshaft speed sensor and situation didn't change. Total spent $1000. and no speedo and no overdrive. Speedo started working intermittantly, seemed like depending on transmission temperature. Friend that works on dodge said is instrument cluster. tried another cluster still the same. Replaced ignition switch, thinking that may be the problem. Still the same. Bought a new Neutral starting switch, which I have not replaced as of yet. If I place truck in neutral and start the truck speedometer is activated right away but does not stay. So right now am down to two scenarios. The neutral starting switch or,...... the temp sensor in the oil line. Feeling is it is the neutral starting switch. By the way had already replaced speed sensor in tranny and rear end. Going to replace neutral starting switch, cost is $25. for the part and see what happens. Please keep us posted, as others are having the same problem.

Speedo


Speedometer gearing damaged or speed sensor problem. It is electronic (no cable).
Since it works intermittantly, I would tend to lean toward the speedo. This may require a swap of the entire cluster.
