If you’ve ever struggled to find the camshaft position sensor on your 6.7 Powerstroke, you’re not alone. I remember searching everywhere under the hood until I found it right where it should be—near the engine’s front, close to the valve cover. In this article, you’ll learn exactly where the 6.7 Powerstroke camshaft position sensor is located and how to spot it quickly.
Where to Look for the Sensor on the Engine
The camshaft position sensor on the 6.7 Powerstroke engine is usually found on the front side of the engine, near the top. It sits close to the valve cover on the passenger side of the truck. This sensor is mounted right next to the camshaft gear and is often held in place with a couple of bolts.
The sensor itself looks like a small plastic part with an electrical connector attached. It reads the position of the camshaft and sends this information to the engine control unit (ECU) so your engine can time the fuel injection and ignition perfectly. Since the 6.7 Powerstroke is a diesel engine, the camshaft position sensor plays a big role in making sure your truck runs smoothly.
Finding this sensor might seem tricky if you’re new to diesel engines, but it’s easier than you think. Open the hood and look on the front of the engine block, just above the fuel filter housing and near the valve cover. The sensor will be attached there, sticking out slightly with a wiring harness clipped to it.
Sometimes the sensor can be covered by dirt or engine grime, so you might want to clean the area before trying to locate it. Also, because the engine is packed tightly, using a flashlight can help you spot the sensor without removing other parts.

How to Identify the Sensor by Its Shape and Connector
The 6.7 Powerstroke camshaft position sensor has a distinctive look that makes it easier to identify once you know what to look for. It is a small, black plastic sensor shaped somewhat like a rectangle but with a rounded edge on one side. The sensor body is usually about 2 to 3 inches long.
Attached to the sensor is a wiring connector that plugs into the truck’s wiring harness. This connector is usually a square or rectangular plastic piece with two or three metal pins inside. The wiring harness itself is often wrapped in protective plastic or tape to shield it from heat and debris.
One way to recognize the camshaft position sensor is by the way it’s mounted. It will be bolted onto the engine block or near the camshaft gear with one or two small bolts. You’ll notice it positioned in line with the camshaft so it can detect its rotation.
The sensor will also have a small gap or airspace where it reads the camshaft’s metal gear or reluctor wheel as it spins. This gap is very narrow, sometimes just a few millimeters, so the sensor can pick up signals accurately.
If you’re unsure which part is the camshaft sensor, check your truck’s repair manual or look up pictures online showing the sensor’s exact shape and location. This can help you compare what you see under your hood with the correct part.
- Small black plastic sensor about 2-3 inches long
- Rounded edges and rectangular shape
- Wiring connector with 2 or 3 pins
- Mounted with 1 or 2 bolts near camshaft gear
- Positioned with a small gap to sense camshaft rotation
- Protective wiring harness attached
What to Do if the Sensor Is Hard to Find or Access
Sometimes, the camshaft position sensor on a 6.7 Powerstroke can be tough to reach because of tight engine compartments or extra parts in the way. If you can’t see the sensor clearly or your hands don’t fit, don’t panic—there are ways to get around this.
First, try removing any covers or shields that might be blocking your view. Some trucks have plastic engine covers or intake parts that can be unscrewed easily with a socket wrench.
If hoses or wires are in the way, gently move them aside but be careful not to pull or damage them. Using small zip tie cutters or pliers can help loosen clips holding wiring harnesses.
Sometimes, it’s helpful to raise the front of your truck using ramps or jack stands. This allows you to look up from underneath the engine to see the sensor from a different angle.
If the sensor is still impossible to reach, it might be best to get professional help. Mechanics have special tools and experience to access hard-to-reach parts without causing damage.
Remember, forcing tools or parts in tight spaces can break delicate wiring or connectors, leading to more costly repairs.

Signs That the Camshaft Position Sensor Needs Checking
The camshaft position sensor is a small part but very important for your 6.7 Powerstroke’s performance. When it starts to fail, your truck will give you some signs that it’s time to check or replace the sensor.
One of the first symptoms is rough engine running. You might notice the engine hesitating or stumbling during acceleration. This happens because the engine’s timing is off when the sensor sends wrong signals.
Another common sign is the check engine light coming on. The truck’s computer detects a problem with the sensor and stores a trouble code. If you have a code reader, you can plug it in and see if the camshaft position sensor is flagged.
Your truck might also have trouble starting or may stall soon after starting. This is because the ECU isn’t getting the right camshaft position information, making it hard to control fuel injection timing.
If you experience any of these problems, checking the sensor’s wiring for damage or loose connections is a good start. Cleaning the sensor or replacing it if necessary can fix the issues quickly.
- Engine runs rough or hesitates during acceleration
- Check engine light turns on
- Trouble starting or engine stalls after start
- Diagnostic trouble codes related to camshaft sensor
- Inspect wiring for damage or loose connectors
- Clean or replace sensor to restore engine timing
