My speedometer worked fine prior to my replacement of the crank position sensor, ignition control module and coil packs. My speedometer now indicates approximately 1 1/2 the normal speed. Is there a vehicle speed sensor that has failed or have I a bad connection?

There is a vss. You may need to remove passenger side front tire. Safely support the vehicle. Are there any applicable trouble codes? The vss is usually in the halfshaft housing.
