03 Expy Air Bag Light

I have a 2003 Expedition. This past weekend the Air Bag Warning light began flashing the code 4 and 2. I read the post regarding disconnecting the battery for 5 minutes and I disconnected it for about 15 and it didn't correct the problem. I then checked the Impact Severity Sensor (after disconnecting the battery - just to be safe), and it appears that the pins for the sensor have become corroded and broken off inside the connector. The sensor costs about $70.00 Canadian, and it doesn't look hard to replace. The Ford Dealership wants about $200.00 just to diagnose the problem ("to be sure"). Is replacing the sensor something that I should attempt (I do the majority of my own car repairs), or should I leave this for the dealership?

Thanks.

You should be able to replace it yourself. I would disconnect the battery for a few minutes before you start to work on it. Just be sure to clean the mounting surfaces realluy good.

Hey, i got the seem problem, where is the sensor located?

The sensor is located at the base of the hood latch support brace (at the bottom of the rad).
