10 Best 7.3 Camshaft Position Sensor Options: Keep Your Powerstroke Running Strong!
If you own a Ford 7.3L Powerstroke diesel, you know it’s a legendary engine – reliable and powerful. But even the best engines have parts that need attention, and the camshaft position sensor (CPS) is definitely one of them. This tiny but mighty component plays a crucial role in your engine’s performance, and a faulty one can quickly turn your trusty truck into a driveway ornament.
The 7.3 camshaft position sensor tells your truck’s computer (PCM) exactly where the camshaft is, which is vital for precise fuel injection and ignition timing. When it goes bad, you might experience frustrating issues like intermittent stalling, rough idling, or even a complete no-start condition. Trust us, you don’t want to be stranded because of a $50 part!
To help you avoid those headaches, we’ve put together a comprehensive guide to the top 10 7.3 camshaft position sensor options available today. We’ll break down what makes each one stand out, so you can pick the perfect replacement for your Powerstroke.
Why a Reliable 7.3 Camshaft Position Sensor Matters
Your Powerstroke’s engine relies on precise timing. The 7.3 CPS acts like the engine’s internal clock, sending signals to the Engine Control Unit (ECU) that dictate when fuel is injected and how the engine fires. If this sensor sends inaccurate or no data, your engine simply won’t know what to do. This can lead to decreased fuel economy, a noticeable drop in power, the dreaded “check engine light,” and as mentioned, serious driveability issues. Investing in a quality 7.3 camshaft position sensor is key to maintaining your diesel engine’s optimal performance and longevity.

How to Choose the Right 7.3 Camshaft Position Sensor
Choosing the best 7.3 camshaft position sensor for your Powerstroke isn’t just about picking the cheapest one. Here’s what to consider:
-
OEM vs. Aftermarket:
- OEM (Original Equipment Manufacturer): Parts like the Ford Genuine or Motorcraft DU-87 are made by or for Ford. They’re typically the most reliable, guarantee a perfect fit, and often come with a Ford warranty. They can be more expensive.
- Aftermarket: Brands like YAOPEI, reilfastprts, SCHNECKE, SZKAIDAG, PREDATOR, and STETIG offer more affordable alternatives. Quality can vary, so look for those that claim to meet or exceed OEM standards, have strong positive reviews, and offer a good warranty.
-
Fitment and Compatibility: This is CRITICAL. Always double-check that the sensor is compatible with your specific truck’s year, make, model, and engine (7.3L Powerstroke). Use the Amazon Parts Finder or cross-reference OE part numbers. Some early 7.3L models might use different sensors.
-
“Black” vs. “Gray” Sensor Debate: Historically, there was a significant difference between the original “black” CPS and the updated “gray” CPS for the 7.3L. The gray sensor (Motorcraft DU-87) was often recommended as a more reliable upgrade. Most modern aftermarket and OEM replacements you buy today will be based on the improved gray sensor design, regardless of their actual color. Still, it’s a good piece of history to be aware of.
-
Warranty: A good warranty can provide peace of mind. Some aftermarket brands offer competitive warranties, as seen with STETIG’s three-year offering.
-
User Reviews: Always read what other 7.3L owners have to say. Real-world experience can highlight potential issues or confirm a product’s reliability.
Frequently Asked Questions (FAQ) About the 7.3 Camshaft Position Sensor
Q1: What does a 7.3 camshaft position sensor (CPS) do?
A: The 7.3 camshaft position sensor monitors the rotational speed and position of the engine’s camshaft. It sends this crucial data to the engine’s computer (PCM or ECU), which then uses it to precisely control fuel injection timing and ignition. Think of it as the engine’s conductor, ensuring everything happens at the right moment.
Q2: What are the common symptoms of a failing 7.3 CPS?
A: Symptoms of a bad 7.3 camshaft position sensor often include:
* Intermittent engine stalling (especially after warming up).
* Engine cranks but won’t start (a common symptom).
* Rough idling or hesitation during acceleration.
* Reduced engine power or poor fuel economy.
* Check Engine Light (CEL) illumination on your dashboard.
* Erratic tachometer readings.
Q3: Is it difficult to replace a 7.3 camshaft position sensor?
A: For many 7.3L Powerstroke owners, replacing the CPS is considered a relatively easy DIY task. It’s located at the front of the engine, usually near the crankshaft pulley or behind the water pump. It typically involves removing one bolt and unplugging a connector. However, always refer to your vehicle’s service manual or a reliable online tutorial for exact steps.
Q4: How often should I replace my 7.3 CPS?
A: There’s no fixed replacement interval for the 7.3 CPS. Many owners carry a spare as a preventative measure due to their known failure rates. It’s generally replaced only when symptoms of failure appear. However, given its critical role and relatively low cost, some prefer to replace it proactively after many years or high mileage.
Q5: Can a faulty 7.3 CPS damage my engine?
A: While a failing 7.3 camshaft position sensor typically won’t cause direct mechanical damage to your engine, it can definitely leave you stranded. The engine simply won’t run properly or at all without accurate camshaft position data. Prolonged driving with a faulty sensor could potentially lead to other issues if the engine isn’t running optimally (e.g., increased emissions or strain on other components), but immediate catastrophic failure is unlikely.
Q6: What’s the difference between the “black” and “gray” 7.3 CPS?
A: Historically, the original “black” 7.3 CPS was prone to failures. Ford later released an updated, more reliable version, which was often referred to as the “gray” sensor (Motorcraft DU-87). The gray sensor is generally considered superior and is the one you want. Most new OEM and reputable aftermarket sensors sold today are based on the improved “gray” design, regardless of their actual casing color.
Q7: Where is the 7.3 CPS located on the engine?
A: On the 7.3L Powerstroke engine, the camshaft position sensor is typically located on the front of the engine block, near the crankshaft pulley. You’ll usually find it mounted in the timing cover, just above or to the side of the crankshaft. It’s often accessible from underneath the front of the truck.
Conclusion
The 7.3 camshaft position sensor might be small, but it’s undoubtedly one of the most vital components keeping your Ford Powerstroke diesel truck roaring down the road. Whether you opt for the undeniable reliability of a genuine OEM part or choose a high-quality aftermarket alternative, making the right choice can save you from inconvenient breakdowns and expensive towing fees.
We hope this detailed guide has helped you understand the importance of this sensor and provided you with the confidence to choose the best replacement for your needs. Keeping a spare on hand is a smart move for any 7.3L owner – it’s a small investment that offers huge peace of mind. Drive on, Powerstroke loyalists!
