Frequently Asked Questions about the 7.3 Crank Position Sensor
Getting answers to common questions can help you better understand and maintain your 7.3 Powerstroke.
Q1: What does a crank position sensor (CMP) do for a 7.3 Powerstroke?
A: For the 7.3L Powerstroke, what’s commonly referred to as the “crank position sensor” is actually the Camshaft Position Sensor (CMP). It monitors the rotation speed and precise position of the camshaft, sending this critical information to the Powertrain Control Module (PCM). The PCM then uses this data to accurately time the fuel injection and ignition, ensuring your engine runs smoothly and efficiently.
Q2: What are the common symptoms of a bad crank position sensor (CMP) on a 7.3?
A: A failing CMP on a 7.3 Powerstroke can cause various noticeable symptoms, including:
* Intermittent engine stalling, especially when hot.
* Engine misfires or rough idling.
* Difficulty starting, or a no-start condition.
* Reduced fuel economy.
* Check Engine Light (CEL) illumination.
* Sudden loss of power or hesitation during acceleration.
Q3: Can I replace a 7.3 crank position sensor (CMP) myself?
A: Yes, replacing the CMP on a 7.3L Powerstroke is generally considered a straightforward DIY task. It’s usually located on the front of the engine, below the water pump, making it relatively accessible. You’ll typically need a few basic tools like a wrench or socket set. There are many helpful videos and guides online that can walk you through the process step-by-step.
Q4: How often should I replace my 7.3 crank position sensor (CMP)?
A: There’s no fixed maintenance schedule for replacing the CMP. It’s usually replaced when it fails or starts exhibiting symptoms. However, some 7.3 owners choose to proactively replace an older, original sensor, especially before a long trip, as it’s a known failure point that can leave you stranded. Keep a spare in your glovebox for emergencies!
Q5: Is an OEM crank position sensor (CMP) better than aftermarket for a 7.3?
A: OEM (Original Equipment Manufacturer) sensors are designed to exact factory specifications and are often considered the most reliable choice, offering a perfect fit and proven performance. However, many high-quality aftermarket sensors can provide excellent performance and reliability at a more affordable price. Brands like Dorman or A-Premium are reputable. The “best” choice often depends on your budget, priorities, and how much confidence you have in a particular aftermarket brand.
Q6: What tools do I need to replace a 7.3 CMP?
A: You’ll typically need:
* A 10mm socket or wrench (for the retaining bolt).
* A flat-head screwdriver (to help pry the old sensor out if it’s stuck).
* Possibly a small pick or hook tool to clear debris.
* Gloves (to protect your hands from oil or grease).
Q7: What’s the difference between a crank and cam sensor on a 7.3?
A: While the main keyword “crank position sensor” is commonly searched, it’s important to clarify for the 7.3L Powerstroke. The 7.3L Diesel engine uses a Camshaft Position Sensor (CMP), not a separate crankshaft position sensor like some gasoline engines. The CMP fulfills the role of providing engine speed and position information to the PCM, which is typically what a “crank position sensor” does in other vehicles. So, for a 7.3, when someone says “crank sensor,” they almost always mean the CMP.
Wrapping Up
Choosing the best crank position sensor for a 7.3 is a critical decision for maintaining the performance and reliability of your beloved Powerstroke. Whether you opt for a genuine Ford OEM part for ultimate peace of mind or a high-quality aftermarket option that offers great value, replacing a faulty sensor promptly is key. With these top picks, you’re well-equipped to make an informed choice and get your 7.3 back to its powerful, reliable self on the road. Drive safe!
