731 gear ratio error 1st gear. If you replaced the sensors, check wiring and check for corrosion, damage...

PO500 is a speed sensor issue. As Raz mentioned, recheck the wiring, plug... to the speed sensor.

The problem is they work on what is called a hall effect. Basically, the sensor is a magnut which produces a current when a steel ring passes it.

Check the wiring for short and open circuit going back to the computer if okay could be the computer itself
