Question about 2005 Chevrolet Impala
My speedometer acts up randomly, but usually when I've been driving for an hour out of town is when it happens.
All of a sudden, it goes haywire, and I'm going 120, 90, 100, but always about 20-40 mph higher than I'm actually going.
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.

Should have mentioned, check engine light is not on, and there are no codes stored in the PCM.
do you think i should be looking at replacing the speedometer guage itself, or start with the vehicle speed sensor? also, are the sensors on the front wheels for the ABS, and the vehicle speed sensor is on the back of the transmission? does this sound correct?
