What does the wrench light mean when it comes on in a e 250 2005 van?

The wrench light in a 2005 E-250 van indicates that the vehicle's powertrain control module (PCM) has detected a problem. It's a general warning light, not specifying the exact issue. The problem could range from something minor (like a loose gas cap) to something more serious (like a transmission problem).

To find out the *specific* problem, you need to have the trouble codes read. You can do this in a few ways:

* OBD-II Scanner: Buy a relatively inexpensive OBD-II code reader from an auto parts store. Plug it into the OBD-II port (usually under the dashboard) and it will read the diagnostic trouble codes (DTCs). These codes will give you a much clearer indication of what's wrong.

* Auto Parts Store: Many auto parts stores will read the codes for free.

* Mechanic: A mechanic will be able to diagnose the problem and recommend repairs.

Ignoring the wrench light can lead to further damage and potentially expensive repairs down the line, so it's best to get it checked as soon as possible.
