This is the procedure from the manual.

1. Monitor APS1 (Green/Red Pin 5) and APS2 (Green/White Pin 2) voltages.

2. Adjust sensor mounting angle so that APS1 output is 0.67v to 0.87v when accelerator is fully released and then tighten the sensor mounting bolt.

3. Under the condition of step 2, APS2 output is within 0.33v to 0.43v.

4. Make sure the accelerator fully depressed stroke is within specified range.

5. With the accelerator fully depressed make sure APS1 output is within 4.4v to 4.6v.

6. Double check accelerator released APS1 output is 0.67v to 0.87v.
