2007 Honda Odyssey starting issue. Solved, details below.

A note on the 2007 Honda Odyssey start system:

In the event you have a 2007 Honda Odyssey and your vehicle will not start, except it is not your starter or battery, it is likely a sensor on the gear selector.

If faulty, the vehicle will display a yellow “D3” and won’t make a noise while trying to start.

To test, while issue is happening, wiggle shift knob and try again. Vehicle should start as if no issue. This is because the sensor wont allow engine start until it detects you are in Park.

If this happens, replace sensor as soon as possible, because the sensor may completely go out and you will need a tow truck.

I hope this helps diagnose starter issues concerning the 2007 Honda Odyssey.
