SOURCE: PO481 code Chevy IMPALA 2003

Looked it up in Chilton's, confirmed in http://www.obd-codes.com/trouble_codes/

P0481 Cooling Fan 2 Control Circuit Malfunction

Each fan will throw a different code. See 3 fans listed for your model. Here's a link for the wiring schematic: http://www.chiltonlibrary.com/content/images/WD/GM/014/WD_GM_014788.pdf


Best of luck.

Chevy impala cuts off while driving


Check for any stored engine codes, this may give you an idea of any problems that may cause your complaint. Possible crank position sensor, cam position sensor or ignition module would cause a 'die in flight' situation.

I have a 2005 chevy impala with miles 147,000 and the check engine light came on


I would have the 2005 Chevy Impala's computer scanned for codes to see what is causing the check engine light to go on. It is not unusual for a 'miss' or an O2 sensor to go bad on such a high mileage vehicle.

Have it checked, though, in order to pinpoint the problem sooner.

Good luck on this repair.
