1. Motorcraft CPS: Top Pick
The Motorcraft CPS is the OEM standard for the 7.3 Powerstroke. In our evaluation, this sensor delivers consistent signal output that matches factory specifications, reducing the risk of stalling or no-start conditions. Owner feedback across forums confirms that the black housing variant outlasts gray aftermarket units, with many reporting trouble-free operation for years. The included gasket ensures a proper seal against oil leaks.
However, this sensor commands a premium price compared to aftermarket alternatives. For those on a tight budget, the cost may be prohibitive. If you prioritize absolute reliability and are willing to pay more, this is the safest choice. But if you need a lower-cost option, consider the Dorman or Standard Motor Products picks below.
- OEM replacement with exact fitment for 7.3 Powerstroke
- Black housing proven more reliable than gray aftermarket
- Includes new gasket for proper sealing
Pros: Factory reliability and consistent signal; Easy plug-and-play installation
Cons: Higher cost than aftermarket options
2. Dorman CPS: Best Value
The Dorman CPS offers a cost-effective solution for 7.3 Powerstroke owners who want the black housing reliability without the OEM price tag. Based on our research, this sensor meets OE specifications and includes a gasket for a straightforward swap. Owner feedback indicates it works well for daily driving and moderate towing, with many reporting thousands of miles of trouble-free service.
However, we found that a small percentage of owners experienced early failure, particularly in high-heat or high-vibration environments. If you frequently push your truck hard with heavy towing or off-road use, you may want to invest in the Motorcraft or a premium aftermarket sensor. For standard use, this is a solid value pick.
- Affordable alternative to Motorcraft with black housing
- Includes gasket for easy installation
- Meets OE form, fit, and function
Pros: Budget-friendly without sacrificing black housing; Good owner reviews for daily driving
Cons: Some units reported early failure in severe conditions
3. Standard Motor Products CPS: Reliable Alternative
Standard Motor Products (SMP) is a well-regarded aftermarket brand, and their CPS for the 7.3 Powerstroke is a reliable alternative. Our evaluation of spec sheets shows it meets OE tolerances, and owner feedback generally praises its performance. The sensor comes with a gasket and is a direct fit, making installation simple.
However, this sensor uses a gray housing, which has historically been associated with higher failure rates in the 7.3 community compared to black housing sensors. While SMP’s quality control may mitigate this, it’s a consideration. If you want the peace of mind of a black housing, consider the Dorman or Motorcraft. This is a good option for those who trust SMP’s reputation.
- Known for consistent quality in aftermarket parts
- Includes gasket and hardware
- Direct fit replacement
Pros: Reliable brand with good track record; Competitive pricing
Cons: Gray housing may be less durable than black; Not as widely tested as Motorcraft
4. Riffraff Diesel CPS: Premium Upgrade
The Riffraff Diesel CPS is a premium aftermarket sensor designed for the 7.3 Powerstroke. Our research indicates it features a reinforced black housing and is built to withstand higher temperatures and vibrations, making it a favorite among truck owners who tow or drive in extreme conditions. Owner reviews consistently highlight its reliability and longevity.
However, this sensor comes at a premium price, often exceeding the Motorcraft cost. It may also be harder to find in stock. If you don’t push your truck hard, the extra cost may not be justified. But for those who demand maximum durability, this is a top contender.
- Reinforced black housing for durability
- Tested for high heat and vibration resistance
- Includes gasket and installation tips
Pros: Enhanced durability over stock; Positive feedback from diesel enthusiasts
Cons: Higher price than standard aftermarket; Limited availability
5. ACDelco CPS: OEM Quality
ACDelco is a reputable OEM supplier, and their CPS for the 7.3 Powerstroke offers similar quality to Motorcraft. Based on our comparison, this sensor uses a black housing and meets strict tolerances. Owner feedback is positive, with many reporting it as a reliable drop-in replacement. It includes a gasket and is easy to install.
However, availability can be an issue, and the price is comparable to Motorcraft. If you prefer ACDelco products or find a good deal, it’s a strong choice. But for most, the Motorcraft remains the standard due to its wider availability and proven track record.
- GM original equipment manufacturer quality
- Black housing for reliability
- Includes gasket
Pros: Trusted brand with rigorous testing; Good alternative to Motorcraft
Cons: May not be as widely available as Motorcraft; Slightly higher price than budget options
6. ATP Automotive CPS: Budget Pick
The ATP Automotive CPS is the most budget-friendly option in our lineup. It is a basic aftermarket sensor with a gray housing and includes a gasket. Our research shows that it can work for some owners, particularly as a stopgap measure to get the truck running. Owner reviews are mixed, with many reporting success for short periods.
However, the gray housing is a known weak point in the 7.3 community, and this sensor has a higher reported failure rate than black housing alternatives. We recommend this only as a temporary replacement or for those with extremely tight budgets. For long-term reliability, spend a bit more on a black housing sensor.
- Lowest cost option for emergency replacement
- Includes gasket
- Direct fit
Pros: Very affordable; Works as a temporary fix
Cons: Gray housing prone to failure; Inconsistent quality control
7. Cardone CPS: Remanufactured Option
The Cardone CPS is a remanufactured sensor that offers an eco-friendly and low-cost alternative. It is rebuilt to OE specifications and comes with a gasket. Our evaluation of owner feedback indicates that while some have had good experiences, others report early failures or intermittent issues. The gray housing is again a concern.
We suggest this only for those who are comfortable with remanufactured parts and have a very limited budget. For most, a new black housing sensor is a better long-term investment. If you choose this, inspect it carefully upon arrival and be prepared for potential replacement sooner than a new unit.
- Remanufactured to OE specs
- Includes gasket and hardware
- Environmentally friendly option
Pros: Low cost; Reduces waste
Cons: Remanufactured quality can vary; Gray housing reliability concerns
Frequently Asked Questions
What is a CPS on a 7.3 Powerstroke?
The CPS (Camshaft Position Sensor) on a 7.3 Powerstroke monitors camshaft position and sends signals to the PCM to control fuel injection timing. A failing CPS can cause stalling, no-start, or rough running.
How do I know if my 7.3 CPS is bad?
Common symptoms include intermittent stalling, hard starting, engine dying while driving, or a check engine light with codes related to camshaft position. Many owners report the truck stalls and then restarts after cooling down.
Should I buy a black or gray housing CPS?
Based on owner feedback and industry discussion, black housing CPS sensors are generally more reliable than gray housing sensors. Gray housings are prone to heat-related failure. We recommend black housing for long-term durability.
Can I replace the CPS myself?
Yes, replacing the CPS on a 7.3 Powerstroke is a straightforward DIY job. It is located on the front of the engine near the harmonic balancer. You’ll need a 10mm socket and possibly a small pry bar. Disconnect the battery, remove the old sensor, install the new one with the included gasket, and reconnect.
How long does a CPS last on a 7.3 Powerstroke?
Lifespan varies, but OEM black housing sensors often last 50,000 to 100,000 miles or more. Aftermarket gray housing sensors may fail sooner, sometimes within 10,000 to 30,000 miles. Heat and vibration are major factors.
Our Verdict
After researching and comparing, our top pick is the Motorcraft CPS for its OEM reliability and proven black housing. The runner-up is the Riffraff Diesel CPS for those seeking enhanced durability in extreme conditions. For budget-conscious buyers, the Dorman CPS offers the best value with a black housing at a lower price.
