My 2003 Focus (manual 1.6) has recently developed a problem whereby randomly the speedometer, rev counter and temperature indicator will all go to zero, the odometer will blank out, and the engine management light comes on. A while later, they all come back on and the engine light goes out.
From a search on here I saw lots of posts about a "Vehicle Speed
Sensor" but this only seemed to be people saying their speedometer went to zero; if the other dials are being lost too, does that still indicate the speed sensor or could it be something else?
I took it to a garage but they couldn't figure out what the problem was ... apparently they plugged their computer in and it didn't show any fault codes.
Any ideas?
