I got off freeway, and truck was idling erracticly and roughly with loss of power. The next day truck started up like normal. I test drove the truck, and same symtoms occurred. This time the check engine light came on. I changed the cam positioner sensor (cps), and reset the computer. I test drove the truck with no problems I had before.

Vehicle began having random stalling or not starting without cranking for a long duration. Finally vehicle stalled in traffic and would not restart. When vehicle stalled a loss of power brakes and power steering was noticed despite the vehicle being a manual transmission and in gear and being back driven as termed by ford motor company. Vehicle required a tow truck to deliver to dealership, where it was determined the cmp sensor was defective. Trouble code p1111 was found by technician. I was told this was a "problematic" part and I should carry a spare in case it happened away from the city. As a result I chose to purchase a spare part and keep it in the glove box for just such a repeat occurrence.

I was driving down the freeway towing a trailer and lost all power to the engine for about 10 seconds. The 1999 ford f350 sd 7.3 diesel engine regained power and surged forward. This happened several times during this trip and subsequent dates. I attached a obd2 reader, which gave me the code for the cam position sensor. I replaced the cps and the problem stopped. The dealer told me that this is a common problem and the parts worker had the part number memorized when he sold me a new one. I now carry a spare cps and a 10 mm wrench in the vehicle in case it happens again. This is a quality control issue or an engineering issue. Please let ford know that I will by a dodge or chevy next time.

The cam position sensor on my '99 ford f-350 w/ 7.3l power stroke is failing intermittently. These failures cause the engine to shut down instantly with no warning. When the engine shuts down there is a loss of power steering and brakes. This has occurred in traffic on interstate 283 in pa causing the vehicle to loss steering and brakes in rush hour traffic with no warning. On one other occasion this occurred in a parking lot causing loss of control of the vehicle while turning due to loss of steering and brakes when the vehicle stalled, causing a minor collision with a curb. No property personal injury occurred. This is a common problem with these vehicles and in my opinion is a very serious safety issue.
