Okay, I have a question, my car has been getting too low of gas mileage on a full tank. Went into the menu where it shows that left tank number is much greater than than right tank about 21 to 6. Is that normal? My gas is about to be on E though.

Hello,

There are two level sensors in the tanks it sounds like one of them is going out. Here is a guide to help you see what you are in for when removing the fuel pumps so we can test the level sensor resistance. (Below) You will need to drain the tank before you begin this video will show you how.

And how to use a voltmeter to check the level sensors on Ohms. Test from the top of the swing to the bottom they should be the same.

Check out the diagrams (below). Please run this test and get back to us.

Cheers, Ken
