Stalling Power Stroke

December 11th, 2009

Hello, my 2000 7.3L Power Stroke has begun intermittently stalling. This seems to occur more often when it is hot outside. It’s not throwing any codes. What could the problem be?

For some time now, Power Stroke owners have focused on the CPS (Cam Position Sensor) as a cause of stalling or not starting. A failing or failed CPS may or may not produce a trouble code.

Ford lists two different part numbers for the CPS, depending on model year range. However, the two are interchangeable with the only apparent difference being a different alloy used in the electrical pins. Some contend that matching the alloy of the connector pins with that of the sensor improves long-term electrical reliability, but those who have used both say there haven’t been any long-term problems when mixing pin alloys.

International refers to the CPS as a “Transmitter”, and lists part number 1825899C93 for about $104, and Ford part number F7TZ-12K073-A sells for about $200. Obviously, based solely on price, the otherwise identical International part has the greater appeal.

The CPS is located on the front of the engine above and slightly toward the driver’s side of the crankshaft harmonic damper, and is best accessed from beneath the truck. Once your stalling problem has been resolved, I’d recommend buying a spare CPS to carry with you at all times.
