Ford recalling 1.2 million diesel trucks

NEW YORK (CNNMoney.com) -- Ford Motor company is recalling about 1.2 million diesel-powered heavy duty pickup trucks and vans because of a computer software problem that could cause their engines to stall.

The trucks being recalled are F-series Super Duty trucks, E-series vans and Excursion SUVs from model years 1997 through 2003 equipped with 7.3-liter diesel engines, according to a letter sent by Ford (Charts, Fortune 500) to the National Highway Traffic Safety Administration.

The issue involves a camshaft position sensor that can degrade over time. The sensor detects the position of the engine's camshaft which controls the opening and closing valves that let air and fuel in and out of the engine's cylinders.

While the engine can stall during driving, power assistance for steering and braking is maintained down to speeds as low as 30 miles per hour, according to Ford, and no deaths or injuries have been reported as a result of stalling.

A few minor accidents have been reported, Ford said.

Not all of the trucks and vans form those model years were equipped with the potentially faulty sensors, Ford said. Customers who believe their vehicles may be affected should call the company at 866-436-7332 or contact a local Ford dealer, the company said.

Letters will be mailed to vehicle owners beginning on Dec. 17, Ford said in its letter.

If necessary, Ford will replace the sensor at no cost.
