Hello, That much of difference should be investigated using a digital scan tool. A little is acceptable, and even expected, but 17-20% is a bit much. The vehicle's output speed sensor should be tested with a digital scan tool, and confirmed to be operational. If the sensor is sending the correct information to the instrument cluster, the instrument cluster may have higher resistance than it should.
