Speedometer reads 100mph at 0 to 1500 rpm and indicates 80mph above 1500 rpm. No other mph readings will indiate on the speedometer. Mileage indicator records miles driven and appears to be working correctly. Check engine light is not on. Code reading is 0. I suspect a speed sensor, but unsure where it is located and if, indeed, this is the problem. Your input is greatly appreciated.

Thank you and have a great weekend.
