Ford F-350 Engine Camshaft Position Sensor Guide (1999-2008)
If you own a 1999-2008 F-350, especially a 7.3L diesel, this is a sensor you need to know about.
- For 7.3L Power Stroke engines, this sensor is a notorious failure point with a history of recalls; carrying a spare is highly recommended.
- Symptoms of failure are severe, including sudden engine stalling, a no-start condition, or a rough idle.
- For this critical part, it is strongly advised to use an OEM Motorcraft sensor or a top-tier aftermarket brand to avoid premature failure.
- The replacement is simple for all engines in this year range, typically involving one bolt and one connector, making it an easy DIY job.
A Critical Sensor for Your F-350
For the 1999-2008 Ford F-350, the camshaft position sensor (CPS) is more than just another part; it's a known point of failure that can leave you stranded. This is especially true for the 7.3L Power Stroke diesel engine. Understanding the symptoms of a bad sensor and choosing the right replacement can save you a major headache.
The Notorious 7.3L Power Stroke CPS (1999-2003)
If you have an F-350 with the 7.3L diesel, the camshaft position sensor is your engine's most famous weak spot. These sensors were so prone to failing without warning that Ford issued a safety recall (NHTSA Recall 07S57) in 2007. The primary danger was that a failed sensor could cause the engine to stall suddenly while driving. The recall involved replacing the original black sensor with an improved gray version (Part No. F7TZ-12K073-B). Many long-time 7.3L owners make it a habit to keep a spare sensor and a 10mm wrench in their glovebox, as the part is easy to change on the side of the road.
Gasoline V8 & V10 Engines (5.4L, 6.8L)
The gas engines in this F-350 generation also have camshaft position sensors that can fail. While not as infamous as the 7.3L part, a bad sensor will still cause similar problems like a no-start condition, stalling, and a rough idle. On these engines, the sensor is typically located on the front of the driver's side cylinder head and is held in by a single 8mm or 5/16" bolt.
6.0L Power Stroke Diesel (2003.5-2008)
The 6.0L Power Stroke has its own list of common engine problems, but the camshaft position sensor is not typically at the top. However, like any electronic component, it can fail and will produce the same set of symptoms: hard starting, stalling, and rough running. If you have a 6.0L, it's important to properly diagnose the issue, as these symptoms can also be caused by other well-known 6.0L issues.
Pro Tip: OEM or Bust for Critical Sensors
While aftermarket parts can save money, the camshaft position sensor is not the place to cut corners on these trucks. Forum discussions among F-350 owners are filled with stories of cheap aftermarket sensors failing quickly or being dead out of the box. For a critical sensor that can shut your engine down, the strong consensus is to use a genuine Motorcraft part or a top-tier OEM supplier like International (for the 7.3L). Paying a little more for a quality part provides peace of mind and reliability.

Frequently Asked Questions
Was there a recall on the F-350 camshaft position sensor?
Yes, Ford issued Safety Recall 07S57 for certain 1997-2003 Ford F-Super Duty trucks with the 7.3L diesel engine. The recall was to replace the original sensor, which could fail and cause the engine to stall. If you own a 7.3L model, you should verify this recall was performed.
Why do 7.3L owners carry a spare CPS?
Because the failure is common, sudden, and can disable the truck completely. However, the replacement is very simple—it's one bolt and one electrical connector in an accessible location. Carrying a spare allows a driver to get the truck running again in minutes, avoiding a tow.
Is the sensor the same for the diesel and gas engines?
No, the sensors are different parts for the 7.3L diesel, 6.0L diesel, and the gasoline engines. They are not interchangeable. You must buy the correct sensor for your specific engine.
My check engine light is on for the CPS. Can I just replace the sensor?
A code like P0340 points to a problem in the sensor's circuit, not necessarily the sensor itself. While the sensor is the most common cause, the issue could also be damaged wiring, a corroded connector, or a problem with the engine computer. Always inspect the wiring and connector when replacing the sensor.
