My '09 Limited check engine light reveals that an oxygen sensor (bank 1, no. 1, before the catalytic converter) needs replacement.

The part from Ford is $190! A compatible part via the web is less than $50.

Has anyone replaced this part yourself? I haven't even been under the car to look around. I've done a fair amount of shadetree repairs, but not this one.

The Ford parts man said it will take a special socket that's available at AutoZone and the like.

I'll appreciate any light you can shed....

I have replace O2 sensors in other cars, it's not at all hard. You could probably borrow the socket from where you purchase the replacement sensor. It's just a deep socket with one side cut away for the wires to go.

Accessibility to the sensor in your Flex may or may not be an issue - take a look for yourself.

Some replacement sensors require you to assemble the connector yourself, so see if yours does. It's not hard, but it may intimidate some people. Just read and follow the directions.

Surprisingly, the "Engine" light that prompted the bad-sensor code readout only glowed 2 days. Before I did anything about it (other than get the code reading) it stopped glowing and has been all quiet since.

Good enough for me!

Midnight Rider - thanks for your response.
