Yes I will solder the connection. Only reason I'm getting that is I can't find a Molex MX64 terminal.

Not exactly easy to find when the pressure is on. Trust me I completely understand

I’m sure it’ll work out though.

Ok so just finished chanthe terminal and boom I'm reading 5V. So now how I'm not reading no DTC codes but my CEL is still on. How do I clear the light?

Nevermind battery disconnected 2 times did the trick.

Trust me I almost gave up I was pissed and it almost beat me. But it's a good thread for anyone that gets the same code.

Now guys can know how to test the DSX flex fuel sensor because I sure didn't.

Recap:

1.Turn key on
2. Unplug sensor only
3. Test power on purple wire should be 12V
4. Test power on white wire should be 5V this wire is coming from pin 38
5. Test ground for continuity.
