I have 2 codes: P1618 and P0722. I think both are related to an output shaft speed sensor. My speedometer and cruise control work fine. Any suggestions?

You need to check them. Check for corrosion or damage to the wiring that could cause the light to come on. However, the sensor itself could be bad and the speedo still work.
