ok i have 02 SD TD and while driving every once and a while the engine will start to choke up and sometimes it will shut off..while this is happening the engine light comes on...it doesnt happen often but if it does happen as soon as i restart the truck the light turns off and the truck runs perfectly normal...any thoughts????
To fix it, you are going to need a 10mm wrench (or socket with a short 3-inch extension). You will also need a flathead screwdriver and, of course, a replacement CPS.
Locate the CPS. It is on the passenger side of the engine block. It is accessible from under the truck and is located at about the 10 o'clock position behind the crankshaft front pulley. Reach up and unplug the wiring harness, remove the 10mm bolt, and GENTLY pry the old CPS out with the flathead screwdriver..
If your Super Duty has the dual alternator package, you may find the second alternator while looking for the CPS. With the dual alternator package, the CPS may not be as easy to see or reach but it is still in the same place.
