YIKES! Speedometer went out

akm3 · 12-24-2002, 07:28 AM

Hey tonight while driving I noticed my speedometer reads zero. All the time. I also noticed my odometer isn't spinning. A couple hours later (I am a delivery driver so I had to keep driving) I got a check engine light.

What now?! Is this sounding expensive or really really cheap?
Any ideas smart Gods of the Cars?

Maybe you could tell us what you're driving....

My wife's Jetta had a bad speedo, fairly common with that year. Required replacing the instrument cluster. $$$

Probably a bad vehicle speed sensor which is located on the transmission. It is an input to the ECU so when it fails you get a CEL. First thing to try would be unplugging the connector and then reconnecting. If reseating the connector doesn't get it working the sensor will most likely have to be replaced. It shouldn't be that expensive, depending on how much the sensor costs. The labor involved is minimal.

Check your altenator to see if it's going on the caput

I second the alternator check, the speedo and odo are the first to go when juice is running low.

Symptoms of bad altenator - Speedo/Tach/Temp gauges go out, then CEL's & ABS lights, then lighting fails with the engine stuttering as well.

I think it's definitely the speed sensor....see if you have a RPM limiter around 4200...thats another symptom of a bad speed sensor.

The part is like $40 and labor is VERY easy. The sensor is located on the passanger side of the transmission and has a wire coming out of it.

Update???

I know it's been a while, but my speedo just died yesterday...and now I can't go past 4000 RPM!

so please.... any updates?

according to what people posted in this thread, I'd say your speed sensor went out. Get another one and replace it and your problems will go away.

The speed sensor is prett easy to replace too. If you have ever done a coolant sensor it will look familiar
