CPS Sensor
I have learned through this site that the CPS is the most common sensor to give any problems. At what milage range do they tend to go and what are the symptoms if any. I have 55k on mine and have developed a slight miss from time to time at idle and around 1500 rpm. Fuel filter was changed 1000mi ago.

Mileage seems to have no effect on the cps. When mine went bad, the engine would die at idle but would immediately restart, or, if you were cruising along it would act like you turned the key off and on real quick. It will continue to get worse until it quits completely.

It's actually not called a CPS as most people call it, it's a CMP Sensor. It can go at any mileage. Symptoms are hesitation or stalling, eventually it won't start and the tach won't move. A bad CMP Sensor does not always throw a code either. If you have questions about part numbers or how to change it check out my contribution to the FAQ in the Super Duty forum.

I own a 96 F-250 PSD and replaced mine at approximatley 120k. Symptoms included a harsh hesitation/miss, usually while the engine was under load. I hummed and hawed about the possible cause with my mechanic for weeks until I convinced him to look at the info available on this site. Sure as ****, it was the CPS. I understand the best deal on CPSs is through an International dealer. I found that our after the installation, which could have resulted in a significant savings.
Good luck

Even though Ford calls it a CMP Sensor, it stands for CaMshaft Position sensor. International calls it a CAMP Sensor.
