Colorado speedometer reads high according to GPS


Find one of those radar displays that sit on the roadside and tell you how fast you're going. Most likely your GPS is the one that's off, because it has to average and estimate your speed, wheras the vehicle's speedometer should be good from the factory.

Speedo and rev counter reading even when engine is off!


I have a similar problems on my 2005 9-3. It has developed a number of minor electical issues. including dial and false warning light triggers. I have fixed most of them by simply going round the car disconnecting the electical connectors and spraying "switch cleaner" (Maplin or Radio Shack).
The only problem I have left is the rev counter occasionally starts reading high, removing the fuse (end of dash panel - 4th fuse down) for about 30s with engine off normally resets everything back to normal.
Hope that helps.

Fast rev problem


Can you tell if the engine speed increased ?
Something in the transmission could be slipping, or the tach could be faulty.

Over sixty mph engine grabs and tach revs? took it to a tranny expert and he said it may be the coil pack?


Not a coil pack at 60 mph

If the tach revs at any speed, your not
locked to the crankshaft

Your tranny guy knows that

Your coming out of torque converter lock-up
or out off gear.

Bad brake switch or if it is only at 60 mph
I would look at speed sensor data,wiring etc.

Get a new guy that knows how to diagnose

Can 215/65/16 tires on a 1999 Caravan be swapped for 205/60/16 tires?


Yes, you'll be o.k. They don't recommend anything over 3% difference, and your at about 1.8%. Speedo will read 61 mph when actually doing 60 mph. Have a look.

1994 honda prelude vtec speedometer tach problem


Possible speed sensor. I know the speed sensors are a problem with hondas. A new speed sensor is about $200 and can be easily replaced. It bolts to the top of the transmission on the firewall side. Do NOT buy an e-bay one. They are only about $30 but are junk
